libc - Fix livelock in nmalloc
* free() -> _slabfree() was turning around and calling _slaballoc()
with the depot lock held, which could lead to a livelock. Fix by
unlocking the depot lock around the call.
* Clean up and document other unrelated bits of nmalloc(). In particular,
clean up magazine_alloc().
