Redo memory-usage mechanism, make it general; add way of dynamically
initializing Lisp object types -- OBJECT_HAS_METHOD(), similar to
CONSOLE_HAS_METHOD().
(1) Create OBJECT_HAS_METHOD(), OBJECT_HAS_PROPERTY() etc. for
specifying that a Lisp object type has a particular method or
property. Call such methods with OBJECT_METH, MAYBE_OBJECT_METH,
OBJECT_METH_OR_GIVEN; retrieve properties with OBJECT_PROPERTY.
Methods that formerly required a DEFINE_*GENERAL_LISP_OBJECT() to
specify them (getprop, putprop, remprop, plist, disksave) now
instead use the dynamic-method mechanism. The main benefit of
this is that new methods or properties can be added without
requiring that the declaration statements of all existing methods
be modified. We have to make the `struct lrecord_implementation'
non-const, but I don't think this should have any effect on speed --
the only possible method that's really speed-critical is the
mark method, and we already extract those out into a separate
(non-const) array for increased cache locality.
Object methods need to be reinitialized after pdump, so we put
them in separate functions such as face_objects_create(),
extent_objects_create() and call them appropriately from emacs.c
The only current object property (`memusage_stats_list') that
objects can specify is a Lisp object and gets staticpro()ed so it
only needs to be set during dump time, but because it references
symbols that might not exist in a syms_of_() function, we
initialize it in vars_of_(). There is also an object property
(`num_extra_memusage_stats') that is automatically initialized based
on `memusage_stats_list'; we do that in reinit_vars_of_alloc(),
which is called after all vars_of_() functions are called.
`disksaver' method was renamed `disksave' to correspond with the
name normally given to the function (e.g. disksave_lstream()).
(2) Generalize the memory-usage mechanism in `buffer-memory-usage',
`window-memory-usage', `charset-memory-usage' into an object-type-
specific mechanism called by a single function
`object-memory-usage'. (Former function `object-memory-usage'
renamed to `total-object-memory-usage'). Generalize the mechanism
of different "slices" so that we can have different "classes" of
memory described and different "slices" onto each class; `t'
separates classes, `nil' separates slices. Currently we have
three classes defined: the memory of an object itself,
non-Lisp-object memory associated with the object (e.g. arrays or
dynarrs stored as fields in the object), and Lisp-object memory
associated with the object (other internal Lisp objects stored in
the object). This isn't completely finished yet and we might need
to further separate the "other internal Lisp objects" class into
two classes.
The memory-usage mechanism uses a `struct usage_stats' (renamed
from `struct overhead_stats') to describe a malloc-view onto a set
of allocated memory (listing how much was requested and various
types of overhead) and a more general `struct generic_usage_stats'
(with a `struct usage_stats' in it) to hold all statistics about
object memory. `struct generic_usage_stats' contains an array of
32 Bytecounts, which are statistics of unspecified semantics. The
intention is that individual types declare a corresponding struct
(e.g. `struct window_stats') with the same structure but with
specific fields in place of the array, corresponding to specific
statistics. The number of such statistics is an object property
computed from the list of tags (Lisp symbols describing the
statistics) stored in `memusage_stats_list'. The idea here is to
allow particular object types to customize the number and
semantics of the statistics where completely avoiding consing.
This doesn't matter so much yet, but the intention is to have the
memory usage of all objects computed at the end of GC, at the same
time as other statistics are currently computed. The values for
all statistics for a single type would be added up to compute
aggregate values for all objects of a specific type. To make this
efficient, we can't allow any memory allocation at all.
(3) Create some additional functions for creating lists that
specify the elements directly as args rather than indirectly through
an array: listn() (number of args given), listu() (list terminated
by Qunbound).
(4) Delete a bit of remaining unused C window_config stuff, also
unused lrecord_type_popup_data.

| 32 /* All windows in use are arranged into a tree, with pointers up and down. | |
| 33 | |
| 34 Windows that are leaves of the tree are actually displayed | |
| 35 and show the contents of buffers. Windows that are not leaves | |
| 36 are used for representing the way groups of leaf windows are | |
| 37 arranged on the frame. Leaf windows never become non-leaves. | |
| 38 They are deleted only by calling delete-window on them (but | |
| 39 this can be done implicitly). Combination windows can be created | |
| 40 and deleted at any time. | |
| 41 | |
| 42 A leaf window has a non-nil buffer field, and also | |
| 43 has markers in its start and pointm fields. Non-leaf windows | |
| 44 have nil in these fields. | |
| 45 | |
| 46 Non-leaf windows are either vertical or horizontal combinations. | |
| 47 | |
| 48 A vertical combination window has children that are arranged on the frame | |
| 49 one above the next. Its vchild field points to the uppermost child. | |
| 50 The parent field of each of the children points to the vertical | |
| 51 combination window. The next field of each child points to the | |
| 52 child below it, or is nil for the lowest child. The prev field | |
| 53 of each child points to the child above it, or is nil for the | |
| 54 highest child. | |
| 55 | |
| 56 A horizontal combination window has children that are side by side. | |
| 57 Its hchild field points to the leftmost child. In each child | |
| 58 the next field points to the child to the right and the prev field | |
| 59 points to the child to the left. | |
| 60 | |
| 61 The children of a vertical combination window may be leaf windows | |
| 62 or horizontal combination windows. The children of a horizontal | |
| 63 combination window may be leaf windows or vertical combination windows. | |
| 64 | |
| 65 At the top of the tree are two windows which have nil as parent. | |
| 66 The second of these is minibuf_window. The first one manages all | |
| 67 the frame area that is not minibuffer, and is called the root window. | |
| 68 Different windows can be the root at different times; | |
| 69 initially the root window is a leaf window, but if more windows | |
| 70 are created then that leaf window ceases to be root and a newly | |
| 71 made combination window becomes root instead. | |
| 72 | |
| 73 In any case, on screens which have an ordinary window and a | |
| 74 minibuffer, prev of the minibuf window is the root window and next of | |
| 75 the root window is the minibuf window. On minibufferless screens or | |
| 76 minibuffer-only screens, the root window and the minibuffer window are | |
| 77 one and the same, so its prev and next members are nil. | |
| 78 | |
| 79 A dead window has the `dead' flag set on it. Note that unlike other | |
| 80 dead objects, dead windows can be made live again through restoring a | |
| 81 window configuration. This means that the values in a dead window | |
| 82 need to be preserved, except for those that are reconstructed by from | |
| 83 the window configuration. */ | |
