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)).

Resolve bootstrapping issues when embedded in FreeBSD libc. b2c0d6322d2307458ae2b28545f8a5c9903d7ef5 (Add witness, a simple online locking validator.) caused a broad propagation of tsd throughout the internal API, but tsd_fetch() was designed to fail prior to tsd bootstrapping. Fix this by splitting tsd_t into non-nullable tsd_t and nullable tsdn_t, and modifying all internal APIs that do not critically rely on tsd to take nullable pointers. Furthermore, add the tsd_booted_get() function so that tsdn_fetch() can probe whether tsd bootstrapping is complete and return NULL if not. All dangerous conversions of nullable pointers are tsdn_tsd() calls that assert-fail on invalid conversion.

size_t alignment, bool zero);
Use rtree-based chunk lookups rather than pointer bit twiddling. Look up chunk metadata via the radix tree, rather than using CHUNK_ADDR2BASE(). Propagate pointer's containing extent. Minimize extent lookups by doing a single lookup (e.g. in free()) and propagating the pointer's extent into nearly all the functions that may need it.
