	lib/libc/stdlib: malloc.3 malloc.c 

Log message:
by popular demand, malloc guard pages.  insert an unreadable/unwriteable
page after each page size allocation to detect overrun.  this is
somewhat electric fence like, while attempting to be mostly usable in
production.  also, use tdeval's chunk randomization code.
enabled with the G option.
