Reimplement malloc/free debugging that includes the offending file:line
info. This turned out to be rather useful on ia64 for tracking down
malloc/free problems.
Detect duplicate free()'s - otherwise these show up as a guard1 failure
and it looks like corruption instead of something simple like a second
free() where there shouldn't be.
Deal with libz using libc headers and not seeing the malloc/free stuff that
we provide in libstand. Do similar nastiness to what is done for bzlib.
Tested on: i386, ia64 (compile, run)
