EXTERNAL_TO_C_STRING returns its argument instead of storing it
in a parameter, and is renamed to EXTERNAL_TO_ITEXT. Similar
things happen to related macros. See entry in src/ChangeLog.
More Mule-izing of postgresql.c. Extract out common code
between `pq-connectdb' and `pq-connect-start'. Fix places
that signal an error string using a formatted string to instead
follow the standard and have a fixed reason followed by the
particular error message stored as one of the frobs.

Changes involving external/internal format conversion,
mostly code cleanup and renaming.
1. Eliminate the previous macros like LISP_STRING_TO_EXTERNAL
that stored its result in a parameter. The new version of
LISP_STRING_TO_EXTERNAL returns its result through the
return value, same as the previous NEW_LISP_STRING_TO_EXTERNAL.
Use the new-style macros throughout the code.
2. Rename C_STRING_TO_EXTERNAL and friends to ITEXT_TO_EXTERNAL,
in keeping with overall naming rationalization involving
Itext and related types.
Macros involved in previous two:
EXTERNAL_TO_C_STRING -> EXTERNAL_TO_ITEXT
EXTERNAL_TO_C_STRING_MALLOC -> EXTERNAL_TO_ITEXT_MALLOC
SIZED_EXTERNAL_TO_C_STRING -> SIZED_EXTERNAL_TO_ITEXT
SIZED_EXTERNAL_TO_C_STRING_MALLOC -> SIZED_EXTERNAL_TO_ITEXT_MALLOC
C_STRING_TO_EXTERNAL -> ITEXT_TO_EXTERNAL
C_STRING_TO_EXTERNAL_MALLOC -> ITEXT_TO_EXTERNAL_MALLOC
LISP_STRING_TO_EXTERNAL
LISP_STRING_TO_EXTERNAL_MALLOC
LISP_STRING_TO_TSTR
C_STRING_TO_TSTR -> ITEXT_TO_TSTR
TSTR_TO_C_STRING -> TSTR_TO_ITEXT
The following four still return their values through parameters,
since they have more than one value to return:
C_STRING_TO_SIZED_EXTERNAL -> ITEXT_TO_SIZED_EXTERNAL
LISP_STRING_TO_SIZED_EXTERNAL
C_STRING_TO_SIZED_EXTERNAL_MALLOC -> ITEXT_TO_SIZED_EXTERNAL_MALLOC
LISP_STRING_TO_SIZED_EXTERNAL_MALLOC
Sometimes additional casts had to be inserted, since the old
macros played strange games and completely defeated the type system
of the store params.
3. Rewrite many places where direct calls to TO_EXTERNAL_FORMAT
occurred with calls to one of the convenience macros listed above,
or to make_extstring().
4. Eliminate SIZED_C_STRING macros (they were hardly used, anyway)
and use a direct call to TO_EXTERNAL_FORMAT or TO_INTERNAL_FORMAT.
4. Use LISP_PATHNAME_CONVERT_OUT in many places instead of something
like LISP_STRING_TO_EXTERNAL(..., Qfile_name).
5. Eliminate some temporary variables that are no longer necessary
now that we return a value rather than storing it into a variable.
6. Some Mule-izing in database.c.
7. Error functions:
-- A bit of code cleanup in maybe_signal_error_1.
-- Eliminate report_file_type_error; it's just an alias for
signal_error_2 with params in a different order.
-- Fix some places in the hostname-handling code that directly
inserted externally-retrieved error strings into the
supposed ASCII "reason" param instead of doing the right thing
and sticking text descriptive of what was going on in "reason"
and putting the external message in a frob.
8. Use Ascbyte instead of CIbyte in process-unix.c and maybe one
or two other places.
9. Some code cleanup in copy_in_passwd() in sysdep.c.
10. Fix a real bug due to accidental variable shadowing in
tstr_to_local_file_format() in win32.c.

| 27 Based on code from pre-release FSF 19, c. 1991. | |
| 28 Various changes by Jamie Zawinski 1991-1994: | |
| 29 converting to ANSI C, splitting out function prototypes to a separate | |
| 30 file (later moved back for unknown reasons by Steve Baur?), debug-gcpro | |
| 31 stuff (now moribund). | |
| 32 ANSI-fication of DEFUN macros by Felix Lee, c. 1992? | |
| 33 NOT_REACHED, DOESNT_RETURN, PRINTF_ARGS by Richard Mlynarik, c. 1994. | |
| 34 Many changes over the years corresponding to Lisp_Object definition | |
| 35 changes, esp. by Richard Mlynarik (c. 1993) and Kyle Jones (c. 1998). | |
| 36 See alloc.c for more details. | |
| 37 Overhauled and reordered by Ben Wing, 1995-1996, and many things added: | |
| 38 Dynarrs, REALLOC macros, asserts, typedefs, inline header code, | |
| 39 first LIST_LOOP macros, CONCHECK_*, all error-checking code | |
| 40 (e.g. error-checking versions of XFOO macros), structure read syntax, | |
| 41 weak lists, lcrecord lists, reworking of quit handling, object hashing, | |
| 42 nested GCPRO, character objects and Ebola checking, memory usage stats, | |
| 43 others. | |
| 44 LOADHIST changes from Steve Baur, c. 1997? | |
| 45 Various macro-related changes by Martin Buchholz, 1998-1999: | |
| 46 LIST_LOOP macros greatly expanded and tortoise-hared; | |
| 47 RETURN_SANS_WARNINGS; reworked DEFUN macros; EXFUN macros (???). | |
| 1743 | 48 Various macro-related changes by Jerry James, 2003: |
| 49 MODULE_API introduced; | |
| 50 Compiler-specific definitions modernized and moved to compiler.h. | |

| 62 "Mule-izing" is the process of going through a file and eliminating | |
| 63 assumptions that the internal format (Ibyte * text) is the same as the | |
| 64 external format used by library routines. Mule-ization should also | |
| 65 include replacing *ALL* raw references to `char' or `unsigned char' with | |
| 66 one of the self-documenting types created below. How exactly to do the | |
| 67 conversion, and how to write correctly Mule-ized code, is described in | |
| 68 the internals manual. Files that say "This file is Mule-ized" have | |
| 69 been reviewed at some point; that's not to say that incorrect code hasn't | |
| 70 crept in, though. | |
| 71 | |
| 72 "Unicode-splitting" is the process of fixing a file so that it will | |
| 73 handle external text in Unicode under Microsoft Windows, as appropriate. | |
| 74 ("splitting" because it needs to handle either Unicode or variable-width | |
| 75 multibyte depending on the OS -- NT or 9x). See intl-win32.c. | |
| 76 | |
| 77 #### is a way of marking problems of any sort. | |

| 79 !!#### marks places that are not properly Mule-ized. | |
| 80 | |
| 81 &&#### marks places that need to be fixed in order for the "8-bit mule" | |
| 82 conversion to work correctly, i.e. in order to support multiple different | |
| 83 buffer formats under Mule, including a fixed 8-bit format. | |
| 84 | |
| 85 ^^#### marks places that need to be fixed in order to eliminate the | |
| 86 assumption that Ibyte * text is composed of 1-byte units (e.g. UTF-16 | |
| 87 is composed of 2-byte units and might be a possible format to consider | |
| 88 for Ibyte * text). | |

| 851 | 1322 We provide MALLOC_OR_ALLOCA() below for places where it's likely that |
| 1323 large amounts will be allocated; it mallocs the block if it's too big. | |
| 1324 Unfortunately, that requires a call to unbind_to() at the end of the | |
| 1325 function, and it's not feasible to rewrite all calls to alloca() this | |
| 1326 way. | |
| 1327 | |
| 1328 Instead, we use the portable C alloca() substitute in alloca.c above a | |
| 1329 certain size. This actually uses malloc(), but checks the current stack | |
| 1330 pointer to see if data from previous alloca() calls needs to be freed. | |
| 1331 However, this can lead to large heap sizes -- especially since cleanup | |
| 1332 can only happen in a parent function, and will never happen if (as will | |
| 1333 often be the case) it's the same function in the same place in the code | |
| 1334 that keeps tripping the alloca() limit. | |
| 1335 | |
| 1336 So we set up a system to periodically force cleanup. Currently we | |
| 1337 do cleanup: | |
| 1338 | |
| 1339 -- Only when there's C alloca() data, and then | |
| 1340 -- Every stack alloca() or allocation of Lisp data, every call to | |
| 1341 next_event_internal() [typically near the top of the stack], | |
| 1342 or every 10th funcall | |
| 1343 | |
| 1344 This should not be a big penalty because | |
| 1345 | |
| 1346 (a) If there are few C alloca() chunks, checking them will be fast | |
| 1347 (b) If not, we've allocated a huge amount of heap space (remember, each | |

| 442 | 2283 /*---------------------- list traversal macros -------------------------*/ |
| 2284 | |
| 2285 /* Note: These macros are for traversing through a list in some format, | |
| 2286 and executing code that you specify on each member of the list. | |
| 2287 | |
| 2288 There are two kinds of macros, those requiring surrounding braces, and | |
| 2289 those not requiring this. Which type of macro will be indicated. | |
| 2290 The general format for using a brace-requiring macro is | |
| 2291 | |
| 2292 { | |
| 2293 LIST_LOOP_3 (elt, list, tail) | |
| 2294 execute_code_here; | |
| 2295 } | |
| 2296 | |
| 2297 or | |
| 2298 | |
| 2299 { | |
| 2300 LIST_LOOP_3 (elt, list, tail) | |
| 2301 { | |
| 2302 execute_code_here; | |
| 2303 } | |
| 2304 } | |
| 2305 | |
| 2306 You can put variable declarations between the brace and beginning of | |
| 2307 macro, but NOTHING ELSE. | |
| 2308 | |
| 2309 The brace-requiring macros typically declare themselves any arguments | |
| 2310 that are initialized and iterated by the macros. If for some reason | |
| 2311 you need to declare these arguments yourself (e.g. to do something on | |
| 2312 them before the iteration starts, use the _NO_DECLARE versions of the | |
| 2313 macros.) | |
| 2314 */ | |
| 2315 | |
| 2316 /* There are two basic kinds of macros: those that handle "internal" lists | |
| 2317 that are known to be correctly structured (i.e. first element is a cons | |
| 2318 or nil, and the car of each cons is also a cons or nil, and there are | |
| 2319 no circularities), and those that handle "external" lists, where the | |
| 2320 list may have any sort of invalid formation. This is reflected in | |
| 2321 the names: those with "EXTERNAL_" work with external lists, and those | |
| 2322 without this prefix work with internal lists. The internal-list | |
| 2323 macros will hit an assertion failure if the structure is ill-formed; | |
| 2324 the external-list macros will signal an error in this case, either a | |
| 2325 malformed-list error or a circular-list error. | |
| 2326 */ | |
| 2327 | |
| 2367 | 2328 /* LIST_LOOP is a simple, old-fashioned macro. It doesn't require brace |
| 2329 surrounding, and iterates through a list, which may or may not known to | |
| 2330 be syntactically correct. It accepts two args, TAIL (set progressively | |
| 2331 to each cons starting with the first), and LIST, the list to iterate | |
| 2332 over. TAIL needs to be defined by the caller. | |
| 442 | 2333 |

| 2347 LIST_LOOP_2 and EXTERNAL_LIST_LOOP_2 are the standard, most-often used | |
| 2348 macros. They take two arguments, an element variable ELT and the list | |
| 2349 LIST. ELT is automatically declared, and set to each element in turn | |
| 2350 from LIST. | |
| 2351 | |
| 2352 LIST_LOOP_3 and EXTERNAL_LIST_LOOP_3 are the same, but they have a third | |
| 2353 argument TAIL, another automatically-declared variable. At each iteration, | |
| 2354 this one points to the cons cell for which ELT is the car. | |
| 2355 | |
| 2356 EXTERNAL_LIST_LOOP_4 is like EXTERNAL_LIST_LOOP_3 but takes an additional | |
| 2357 LEN argument, again automatically declared, which counts the number of | |
| 2358 iterations gone by. It is 0 during the first iteration. | |
| 2359 | |

| 2362 them yourself. (ELT and TAIL are Lisp_Objects, and LEN is an EMACS_INT.) | |

| 771 | 3886 /* When support for message translation exists, GETTEXT() translates a |
| 3887 string from English into the language defined by | |
| 3888 `current-language-environment'. This is done by looking the string | |
| 3889 up in a large predefined table; if no translation is found, the | |
| 3890 original string is returned, and the failure is possibly logged so | |
| 3891 that the translation can later be entered into the table. | |
| 3892 | |
| 3893 In addition to this, there is a mechanism to snarf message strings | |
| 3894 out of the source code so that they can be entered into the tables. | |
| 3895 This is what make-msgfile.lex does. | |
| 3896 | |
| 3897 Handling `format' strings is more difficult: The format string | |
| 3898 should get translated, but not under all circumstances. When the | |
| 3899 format string is a Lisp string, what should happen is that | |
| 3900 Fformat() should format the untranslated args[0] and return that, | |
| 3901 and also call Fgettext() on args[0] and, if that is different, | |
| 3902 format it and store it in the `string-translatable' property of the | |
| 3903 returned string. See Fgettext(). | |

| 4023 | |
| 4024 The C++ code below catches GCPRO without UNGCPRO or vice-versa. | |
| 4025 Catching cases where there's no GCPRO or UNGCPRO but should be, however, | |
| 4026 is much harder, but could be done: | |
| 4027 | |
| 4028 1. Lisp_Object becomes a real object. Its creator and destructor need to | |
| 4029 figure out whether the object is on the stack (by looking at the range | |
| 4030 that `this' is within), and if so, add the pointer to a list of all | |
| 4031 stack-based Lisp_Objects. | |
| 4032 | |
| 4033 2. The assignment method needs to do reference-counting on actual Lisp | |
| 4034 objects -- in particular, we need to know if there are any references | |
| 4035 to a Lisp object that are *NOT* from stack-based Lisp_Objects. | |
| 4036 | |
| 4037 3. When we get to a point in the code where we might garbage collect -- | |
| 4038 i.e. Ffuncall(), Feval(), or Fgarbage_collect() is called -- we look | |
| 4039 at our list of stack-based Lisp_Objects, and if there are any that | |
| 4040 point to Lisp objects with no non-stack references, see if there are | |
| 4041 any gcpros pointing to the object, and if not, set a flag indicating | |
| 4042 that the object is "destroyed". (Don't abort yet because the function | |
| 4043 might not use the object any more.) | |
| 4044 | |
| 4045 4. When we detag a pointer using XFOO(), abort if its "destroyed" flag | |
| 4046 is set. | |
