/*
* Cruft for supporting old API levels. Pre-L we didn't have
* pthread_mutex_timedlock, instead we had pthread_mutex_lock_timeout_np. NDK
* users targeting pre-L still need this, but anyone targeting L or newer (or
* LP64 code) should just use pthread_mutex_timedlock.
* Cruft for supporting old API levels. Pre-L we didn't have the proper POSIX
* APIs for things, but instead had some locally grown, artisan equivalents.
* Keep exposing the old prototypes on old API levels so we don't regress
* functionality.
