Define public GC_[p]valloc() and redirect to them in leak_detector.h
Issue #495 (bdwgc).
* doc/README.macros (GC_NO_VALLOC): Document.
* doc/leak.md: Mention GNU valloc and pvalloc functions.
* include/gc/gc.h (GC_memalign): Remove comment that it is not tested;
add comment describing the functionality and a note.
* include/gc/gc.h [!GC_NO_VALLOC] (GC_valloc, GC_pvalloc): Declare
new API function.
* include/gc/leak_detector.h [!GC_NO_VALLOC] (valloc, pvalloc):
Redefine to the corresponding GC_ function.
* include/private/gc_priv.h (GC_page_size): Add comment.
* include/private/gc_priv.h (GC_real_page_size): Declare new variable
(or as a macro).
* include/private/gcconfig.h [NACL] (GETPAGESIZE): Add TODO item.
* mallocx.c (GC_memalign): Likewise.
* tests/gctest.c (run_one_test): Likewise.
* include/private/gcconfig.h [CYGWIN32 && (MPROTECT_VDB || USE_MUNMAP)
|| !MSWIN32 && !MSWINCE && !CYGWIN32 && (GC_DISABLE_INCREMENTAL
|| DEFAULT_VDB) && !USE_MMAP] (ALT_PAGESIZE_USED): Define macro.
* include/private/gcconfig.h [CYGWIN32 && (MPROTECT_VDB || USE_MUNMAP)
|| !MSWIN32 && !MSWINCE && !CYGWIN32 && (GC_DISABLE_INCREMENTAL
|| DEFAULT_VDB) && !USE_MMAP && !GC_NO_VALLOC] (REAL_PAGESIZE_NEEDED):
Likewise.
* mallocx.c (GC_strdup): Reformat comment.
* mallocx.c [!GC_NO_VALLOC] (GC_valloc, GC_pvalloc): Implement.
* os_dep.c [REAL_PAGESIZE_NEEDED] (GC_real_page_size): Define variable.
* os_dep.c [MSWIN32 || MSWINCE || CYGWIN32] (GC_setpagesize): Replace
CYGWIN32&&(MPROTECT_VDB||USE_MUNMAP) to ALT_PAGESIZE_USED; remove
comment that a separate variable could be added; reformat comment;
assert about GC_pagesize only if REAL_PAGESIZE_NEEDED.
* os_dep.c [ALT_PAGESIZE_USED && REAL_PAGESIZE_NEEDED]
(GC_setpagesize): Set GC_real_page_size.
* os_dep.c [!MSWIN32 && !MSWINCE && !CYGWIN32] (GC_setpagesize):
Replace MPROTECT_VDB||PROC_VDB||SOFT_VDB||USE_MMAP to
!ALT_PAGESIZE_USED.
* tests/gctest.c [!GC_NO_VALLOC] (run_one_test): Call GC_valloc() and
GC_pvalloc().
