Get rid of the VALGRIND_INTERNAL_PRINTF_BACKTRACE request -- it's no longer
used.

And move VALGRIND_INTERNAL_PRINTF() out of core.h into vg_replace_malloc.c,
which is the only place it's used now.  Also made it print it's message with
Vg_DebugMsg rather than Vg_UserMsg, which makes more sense, since it's used
for --trace-malloc which is debugging-style info.

Improved some comments about this stuff too.
