This patch makes it so jemalloc is not included in firefox. Not accepted by
the upstream community.
Put jemalloc inside libxul. Then need firefox to depend on libxul
and build jemalloc library.
Remove lines - do not include memory for every program
Need to create/add our own versions of the functions malloc_usable, jemalloc_stats, etc.
Remove mozalloc library
Check if we have jemalloc; if not, skip it.
Build libxul and use flags -Wl,-z,interpose, needed to build the library.
