Implement configuration system.
Implement minimal Makefile. Make compile-time-optional jemalloc features controllable via configure options (debug, stats, tiny, mag, balance, dss). Conditionally exclude most of the opt_* run-time options, based on configure options (fill, xmalloc, sysv). Implement optional --enable-dynamic-page-shift. Implement optional --enable-lazy-lock. Re-order malloc_init_hard() and use the malloc_initializer variable to support recursive allocation in malloc_ncpus(). Add mag_rack_tsd in order to receive notifications of thread termination. Add jemalloc.h.
