clean up, rearrange allocation statistics code
-------------------- ChangeLog entries follow: --------------------
src/ChangeLog addition:
2010-03-21 Ben Wing <ben@xemacs.org>
* alloc.c:
* alloc.c (assert_proper_sizing):
* alloc.c (c_readonly):
* alloc.c (malloced_storage_size):
* alloc.c (fixed_type_block_overhead):
* alloc.c (lisp_object_storage_size):
* alloc.c (inc_lrecord_stats):
* alloc.c (dec_lrecord_stats):
* alloc.c (pluralize_word):
* alloc.c (object_memory_usage_stats):
* alloc.c (Fobject_memory_usage):
* alloc.c (compute_memusage_stats_length):
* alloc.c (disksave_object_finalization_1):
* alloc.c (Fgarbage_collect):
* mc-alloc.c:
* mc-alloc.c (mc_alloced_storage_size):
* mc-alloc.h:
No functionality change here. Collect the allocations-statistics
code that was scattered throughout alloc.c into one place. Add
remaining section headings so that all sections have headings
clearly identifying the start of the section and its purpose.
Expose mc_alloced_storage_size() even when not MEMORY_USAGE_STATS;
this fixes build problems and is related to the export of
lisp_object_storage_size() and malloced_storage_size() when
non-MEMORY_USAGE_STATS in the previous change set.

| 73 8 DLU per button plus 4 DLU per character. | |
| 74 max (32, 6 * text_length). The factor of six is rather empirical, but it | |
| 75 works better than 8 which comes from the definition of a DLU. Buttons are | |
| 76 spaced with 6 DLU gap. Minimum distance from the button to the left or right | |
| 77 dialog edges is 6 DLU, and the distance between the dialog bottom edge and | |
| 78 buttons is 7 DLU. | |

| 93 plus 8 DLU per each line of text. Distance between the bottom edge of the | |

| 95 is 100 DLU, thus giving minimum dialog weight of 112 DLU. Maximum width is | |

| 113 Layout algorithm | |
| 114 ---------------- | |
| 115 First we calculate the minimum width of the button row, excluding "from | |
| 116 edge" distances. Note that the static control text can be narrower than | |
| 117 X_AVE_TEXT only if both text and button row are narrower than that (so, | |
| 118 even if text *can* be wrapped into 2 rows narrower than ave width, it is not | |
| 119 done). Let WBR denote the width of the button row. | |
| 120 | |
| 121 Next, the width of the static field is determined. | |
| 122 First, if all lines of text fit into max (WBR, X_MAX_TEXT), the width of the | |
| 123 control is the same as the width of the longest line. | |
| 124 Second, if all lines of text are narrower than X_MIN_TEXT, then width of | |
| 125 the control is set to X_MIN_TEXT. | |
| 126 Otherwise, width is set to max(WBR, X_AVE_TEXT). In this case, line wrapping will | |
| 127 happen. | |
| 128 | |
| 129 If width of the text control is larger than that of the button row, then the | |
| 130 latter is centered across the dialog, by giving it extra edge | |
| 131 margins. Otherwise, minimal margins are given to the button row. | |
