d3068c3f46 _pt_thread_death_internal(), which is part of Linux's nptl pthreads
implementation, calls free() after calling TSD destructors.  This was causing a
crash during thread exit, since the magazine rack was no longer valid for the
thread.  Fix this by using a special mag_rack value to indicate that
deallocation should bypass the magazine machinery.

cc00a15770 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.

b7924f50c0 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.
