[util] Import my malloc wrapper that prints simple statistics

To build, do:

	make malloc-stats.so

inside util/, and to use, run:

	LD_PRELOAD=malloc-stats.so some-program

For binaries managed by libtool, eg, cairo-perf, do:

	../libtool --mode=execute /bin/true ./cairo-perf
	LD_PRELOAD="../util/malloc-stats.so" .libs/lt-cairo-perf

The code also includes Jeff Muizelaar's libbacktracesymbols that
is a much better implementation of backtrace_symbols() than what
is provided by glibc.  That can be built by:

	make backtrace-symbols.so
