Redo the dynarr code, add greater checks.
Rename the `len', `largest' and `max' members to `len_',
`largest_' and `max_' to try and catch existing places that might
directly modify these values. Make new accessors Dynarr_largest()
and Dynarr_max() and make them and existing Dynarr_length() be
non-lvalues by adding '+ 0' to them; fix a couple of places in the
redisplay code that tried to modify the length directly by setting
Dynarr_length(). Use the accessors whenever possible even in the
dynarr code itself. The accessors also verify that 0 <= len <=
largest <= max. Rename settor function Dynarr_set_size() to
Dynarr_set_length() and use it more consistently; also create
lower-level Dynarr_set_length_1(). This latter function should be
the only function that directly modifies the `len_' member of a
Dynarr, and in the process makes sure that the `largest' value is
kept correct.
Consistently use ERROR_CHECK_STRUCTURES instead of
ERROR_CHECK_TYPES for error-checking code. Reintroduce the
temporarily disabled verification code on the positions of
Dynarr_at(), Dynarr_atp() and Dynarr_atp_past_end().
Also create Dynarr_resize_if() in place of a repeated
code fragment. Clean up all the functions that modify Dynarrs to
use the new macros and functions and verify the correctness of the
Dynarr both before and after the change.
Note that there are two kinds of verification -- one for accessing
and one for modifying. The difference is that the modify
verification additionally checks to make sure that the Dynarr
isn't locked. (This is used in redisplay to check for problems
with reentrancy.)
* lrecord.h: Move XD_DYNARR_DESC to lisp.h, grouping with the dynarr code.

| 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. | |
| 78 | |
| 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). | |
| 89 | |

| 851 | 1321 We provide MALLOC_OR_ALLOCA() below for places where it's likely that |
| 1322 large amounts will be allocated; it mallocs the block if it's too big. | |
| 1323 Unfortunately, that requires a call to unbind_to() at the end of the | |
| 1324 function, and it's not feasible to rewrite all calls to alloca() this | |
| 1325 way. | |
| 1326 | |
| 1327 Instead, we use the portable C alloca() substitute in alloca.c above a | |
| 1328 certain size. This actually uses malloc(), but checks the current stack | |
| 1329 pointer to see if data from previous alloca() calls needs to be freed. | |
| 1330 However, this can lead to large heap sizes -- especially since cleanup | |
| 1331 can only happen in a parent function, and will never happen if (as will | |
| 1332 often be the case) it's the same function in the same place in the code | |
| 1333 that keeps tripping the alloca() limit. | |
| 1334 | |
| 1335 So we set up a system to periodically force cleanup. Currently we | |
| 1336 do cleanup: | |
| 1337 | |
| 1338 -- Only when there's C alloca() data, and then | |
| 1339 -- Every stack alloca() or allocation of Lisp data, every call to | |
| 1340 next_event_internal() [typically near the top of the stack], | |
| 1341 or every 10th funcall | |
| 1342 | |
| 1343 This should not be a big penalty because | |
| 1344 | |
| 1345 (a) If there are few C alloca() chunks, checking them will be fast | |
| 1346 (b) If not, we've allocated a huge amount of heap space (remember, each | |
| 1347 chunk represents > 256K of heap), and we really want them gone | |

| 2284 /* Note: These macros are for traversing through a list in some format, | |
| 2285 and executing code that you specify on each member of the list. | |
| 2286 | |
| 2287 There are two kinds of macros, those requiring surrounding braces, and | |
| 2288 those not requiring this. Which type of macro will be indicated. | |
| 2289 The general format for using a brace-requiring macro is | |
| 2290 | |
| 2291 { | |
| 2292 LIST_LOOP_3 (elt, list, tail) | |
| 2293 execute_code_here; | |
| 2294 } | |
| 2295 | |
| 2296 or | |
| 2297 | |
| 2298 { | |
| 2299 LIST_LOOP_3 (elt, list, tail) | |
| 2300 { | |
| 2301 execute_code_here; | |
| 2302 } | |
| 2303 } | |
| 2304 | |
| 2305 You can put variable declarations between the brace and beginning of | |
| 2306 macro, but NOTHING ELSE. | |
| 2307 | |
| 2308 The brace-requiring macros typically declare themselves any arguments | |
| 2309 that are initialized and iterated by the macros. If for some reason | |
| 2310 you need to declare these arguments yourself (e.g. to do something on | |
| 2311 them before the iteration starts, use the _NO_DECLARE versions of the | |
| 2312 macros.) | |
| 2313 */ | |
| 2314 | |
| 2315 /* There are two basic kinds of macros: those that handle "internal" lists | |
| 2316 that are known to be correctly structured (i.e. first element is a cons | |
| 2317 or nil, and the car of each cons is also a cons or nil, and there are | |
| 2318 no circularities), and those that handle "external" lists, where the | |
| 2319 list may have any sort of invalid formation. This is reflected in | |
| 2320 the names: those with "EXTERNAL_" work with external lists, and those | |
| 2321 without this prefix work with internal lists. The internal-list | |
| 2322 macros will hit an assertion failure if the structure is ill-formed; | |
| 2323 the external-list macros will signal an error in this case, either a | |
| 2324 malformed-list error or a circular-list error. | |
| 2325 */ | |
| 2326 | |
| 2367 | 2327 /* LIST_LOOP is a simple, old-fashioned macro. It doesn't require brace |
| 2328 surrounding, and iterates through a list, which may or may not known to | |
| 2329 be syntactically correct. It accepts two args, TAIL (set progressively | |
| 2330 to each cons starting with the first), and LIST, the list to iterate | |
| 2331 over. TAIL needs to be defined by the caller. | |
| 442 | 2332 |
| 2333 In each iteration, you can retrieve the current list item using XCAR | |
| 2334 (tail), or destructively modify the list using XSETCAR (tail, | |
| 2335 ...). */ | |

| 2345 | |
| 2346 LIST_LOOP_2 and EXTERNAL_LIST_LOOP_2 are the standard, most-often used | |
| 2347 macros. They take two arguments, an element variable ELT and the list | |
| 2348 LIST. ELT is automatically declared, and set to each element in turn | |
| 2349 from LIST. | |
| 2350 | |
| 2351 LIST_LOOP_3 and EXTERNAL_LIST_LOOP_3 are the same, but they have a third | |
| 2352 argument TAIL, another automatically-declared variable. At each iteration, | |
| 2353 this one points to the cons cell for which ELT is the car. | |
| 2354 | |
| 2355 EXTERNAL_LIST_LOOP_4 is like EXTERNAL_LIST_LOOP_3 but takes an additional | |
| 2356 LEN argument, again automatically declared, which counts the number of | |
| 2357 iterations gone by. It is 0 during the first iteration. | |
| 2358 | |
| 2359 EXTERNAL_LIST_LOOP_4_NO_DECLARE is like EXTERNAL_LIST_LOOP_4 but none | |
| 2360 of the variables are automatically declared, and so you need to declare | |
| 2361 them yourself. (ELT and TAIL are Lisp_Objects, and LEN is an EMACS_INT.) | |

| 4022 | |
| 4023 The C++ code below catches GCPRO without UNGCPRO or vice-versa. | |
| 4024 Catching cases where there's no GCPRO or UNGCPRO but should be, however, | |
| 4025 is much harder, but could be done: | |
| 4026 | |
| 4027 1. Lisp_Object becomes a real object. Its creator and destructor need to | |
| 4028 figure out whether the object is on the stack (by looking at the range | |
| 4029 that `this' is within), and if so, add the pointer to a list of all | |
| 4030 stack-based Lisp_Objects. | |
| 4031 | |
| 4032 2. The assignment method needs to do reference-counting on actual Lisp | |
| 4033 objects -- in particular, we need to know if there are any references | |
| 4034 to a Lisp object that are *NOT* from stack-based Lisp_Objects. | |
| 4035 | |
| 4036 3. When we get to a point in the code where we might garbage collect -- | |
| 4037 i.e. Ffuncall(), Feval(), or Fgarbage_collect() is called -- we look | |
| 4038 at our list of stack-based Lisp_Objects, and if there are any that | |
| 4039 point to Lisp objects with no non-stack references, see if there are | |
| 4040 any gcpros pointing to the object, and if not, set a flag indicating | |
| 4041 that the object is "destroyed". (Don't abort yet because the function | |
| 4042 might not use the object any more.) | |
| 4043 | |
| 4044 4. When we detag a pointer using XFOO(), abort if its "destroyed" flag | |
