	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.
