0a62889c7a155f8ed971860d68870dc9c46bb004 jit: Use std::mutex instead of pthread_mutex_t
This allows JIT to be built with a different thread model from posix
where pthread isn't available
By renaming the acquire_mutex () and release_mutex () member functions
to lock() and unlock() we make the playback::context type meet the C++
Lockable requirements. This allows it to be used with a scoped lock
(i.e. RAII) type as std::lock_guard. This automatically releases the
mutex when leaving the scope.
