If a custom small_size2bin table was required due to non-default size class settings, memory allocation prior to initializing chunk parameters would cause a crash due to division by 0. The fix re-orders the various *_boot() function calls. Bootstrapping is simpler now than it was before the base allocator started just using the chunk allocator directly. This allows arena_boot[01]() to be combined. Add error detection for pthread_atfork() and atexit() function calls.
