Remove all functionality related to tracing. This functionality was
useful for understanding memory fragmentation during early algorithmic
design of jemalloc, but it had little utility for non-trivial
applications, due to the sheer volume of data written to disk.
Replace chunk stats code that was missing locking; this fixes a race
condition that could corrupt chunk statistics.
Converting malloc_stats_print() to use mallctl*().
Add a missing semicolon in th DSS code.
Convert malloc_tcache_flush() to a mallctl.
Convert malloc_swap_enable() to a set of mallctl's.
Fix a stats bug in large object curruns accounting.
Replace tcache_bin_fill() with arena_tcache_fill(), and fix a bug in an OOM
error path.
Fix API name mangling to coexist with __attribute__((malloc)).
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.
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.
