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.
