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.

Add arena-specific and selective dss allocation. Add the "arenas.extend" mallctl, so that it is possible to create new arenas that are outside the set that jemalloc automatically multiplexes threads onto. Add the ALLOCM_ARENA() flag for {,r,d}allocm(), so that it is possible to explicitly allocate from a particular arena. Add the "opt.dss" mallctl, which controls the default precedence of dss allocation relative to mmap allocation. Add the "arena.<i>.dss" mallctl, which makes it possible to set the default dss precedence on a per arena or global basis. Add the "arena.<i>.purge" mallctl, which obsoletes "arenas.purge". Add the "stats.arenas.<i>.dss" mallctl.

Refactor tests. Refactor tests to use explicit testing assertions, rather than diff'ing test output. This makes the test code a bit shorter, more explicitly encodes testing intent, and makes test failure diagnosis more straightforward.

#ifdef JEMALLOC_H_EXTERNS
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.
