Refactor jemalloc.c into multiple source files. 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)).

Add the --enable-swap configure option. Add malloc_swap_enable(). Add the O/o JEMALLOC_OPTIONS flags, which control memory overcommit. Fix mapped memory stats reporting for arenas.

extern size_t opt_lg_chunk;
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.

Port to Mac OS X. Add Mac OS X support, based in large part on the OS X support in Mozilla's version of jemalloc.

Omit chunk header in arena chunk map. Omit the first map_bias elements of the map in arena_chunk_t. This avoids barely spilling over into an extra chunk header page for common chunk sizes.
