I have changed how `make-mutex' works. Now it accepts an optional
argument; if the argument is non nil then a recursive mutex is created,
by default it is nil. By default a normal mutex (non recursive) is
created.
I have also changed mutex-unlock on a recursive mutex to match the
number of times it was mutex-lock'ed. To release a recursive mutex it
must be unlocked as many times as it was locked.
I have added a mutexp function that I forgot to add before.
