- Reimplemented mutex to use the _kern_mutex*() syscalls.
- The initializer functions cannot fail anymore -- changed their return type
to void.
- Changed the initializer function semantics to not copy the name by default
anymore (as in the kernel). Also added *_etc() versions of them that take an
additional flags.
- Added static initializer macros.
- Made the mutex (and thus recursive_lock) lock functions non-interruptable.
- Got rid of the "lazy" version. They are no longer needed, since the
initialization of the standard types can be done statically and cannot fail.
* Adjusted libroot, runtime loader, and other code using the private libroot
locking primitives to the new semantics.
* pthreads mutexes and condition variables:
- Reimplemented using the _kern_mutex*() syscalls.
- Consistently use POSIX error codes.
- Fixed some not quite POSIX compliant behavior.
