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.
