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.
