Fix bogosity in implementation of ACQUIRE_LOCK/RELEASE_LOCK on Win32.
These functions were essentially doing nothing, due to a missing
dereference on the argument.

I've rewritten them as inlines (to catch type errors) and added some
checking of the return values, which should help catch errors like
this in the future.
