d8f565f239 Remove tcache bin sorting during flush.
This feature caused significant performance degradation, and the
fragmentation reduction benefits were difficult to quantify.

c66aaf1476 Statistics fixes and cleanup.
Fix a type mismatch for "arenas.nlruns" mallctl access.  This bug caused
a crash during statistics printing on 64-bit systems.

Fix the "stats.active" mallctl to include active memory in huge objects.

Report active bytes for the whole application, as well as per arena.

Remove several unused variables.

3c2343518c Implement mallctl{nametomib,bymib}().
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.

279e09d1ff Enhance the H/h MALLOC_OPTIONS flags to control the number of tcache bin slots,
rather than just enabling/disabling the tcache.

03c2237af3 Make malloc_stats_print() a public symbol, and make it repeatedly callable.
Incrementally merge tcache stats, so that malloc_stats_print() always reports
at least most events that have occurred thus far.

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.
