difference that the initialization function has an additional void* argument,
so that it is suitable for initializing stuff in objects.

* Split locks.cpp into mutex.cpp, recursive_lock.cpp, and rw_lock.cpp (new
subdirectory locks/).
* runtime_loader no longer includes the rw_lock, allowing removal of the TLS
dependency again.

as a mutex, but allocates its semaphore lazily. This comes at the cost of an
additional atomic_add() when the semaphore has actually to be acquired, but
saves the semaphore creation completely in single-threaded programs and in
any program when there's no lock contention.

libroot. The mutex is a simple benaphore, the rw_lock is pretty much the same
as the one from libkernelland_emu but uses a mutex per lock instead of emulating
a global thread lock. Also added MutexLocking and RWLock{Read|Write}Locking and
AutoLockers based on them. It's cased with __cplusplus so the locks are also
usable from C. Everything's currently exposed in shared/private/locks.h but I
think we should make these locking primitves public.
