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.

Clean up the manpage and conditionalize various portions according to how jemalloc is configured. Modify arena_malloc() API to avoid unnecessary choose_arena() calls. Remove unnecessary code from choose_arena(). Enable lazy-lock by default, now that choose_arena() is both faster and out of the critical path. Implement objdir support in the build system.
