  Modified files:
    lib/libc/stdlib      malloc.3 malloc.c 
  Log:
  Bring in a bunch of malloc features from OpenBSD and fundamentally change
  the core allocation code to use mmap() instead of brk/sbrk().  Most of the
  new options are off by default, see the new manual page for more information.
  
  * guard pages and chunk randomization
  * free page protection
  * malloc stats(dump)
  * pointer guard
  * no longer uses brk/sbrk
  * updated man page
