Christopher Faylor c7e2187a60 * Makefile.in: Add support for new malloc.o and renamed malloc_wrapper.o. Use
-fomit-frame-pointer for malloc.o compilation.
* malloc_wrapper.cc: New file.  Rename from malloc.cc.  Add support for more
malloc functions.  Eliminate export_* calls.  Just use straight malloc names.
Remove unused argument from malloc lock functions.
* cygwin.din: Just export straight malloc names.  Add malloc_stats,
malloc_trim, malloc_usable_size, mallopt, memalign, valloc.
* dcrt0.cc (__cygwin_user): Eliminate export_* malloc entries.
* fork.cc (fork_parent): Remove unused argument from malloc_lock argument.
* malloc.cc: New file.  Doug Lea's malloc v2.7.1.
* cygmalloc.h: New file.
* include/cygwin/version.h: Bump API_MINOR.
* sync.h (muto::acquire): Use appropriate number for regparm attribute.
(muto::reset): Ditto.
(muto::release): Ditto.
