* libcsupport/Makefile.am, libcsupport/preinstall.am, libcsupport/src/malloc.c, libcsupport/src/mallocinfo.c, libmisc/Makefile.am, libmisc/shell/main_mallocinfo.c, libmisc/shell/shellconfig.h: Split malloc.c into multiple files with one function per file. Also split out statistics into a separate file which can be plugged in dynamically. Right now, it is always in. I suspect that splitting the file removed more code than leaving statistics in. I tinkered with malloc information command in the shell. I resurrected the malloc arena code as malloc boundary. This code is now compiled all the time even though it does not appear to work. * libcsupport/include/rtems/malloc.h, libcsupport/src/_calloc_r.c, libcsupport/src/_free_r.c, libcsupport/src/_malloc_r.c, libcsupport/src/_realloc_r.c, libcsupport/src/calloc.c, libcsupport/src/free.c, libcsupport/src/malloc_boundary.c, libcsupport/src/malloc_get_statistics.c, libcsupport/src/malloc_initialize.c, libcsupport/src/malloc_p.h, libcsupport/src/malloc_report_statistics.c, libcsupport/src/malloc_report_statistics_plugin.c, libcsupport/src/malloc_statistics_helpers.c, libcsupport/src/malloc_walk.c, libcsupport/src/realloc.c, libmisc/shell/main_perioduse.c: New files.
