mutex: add __fio_mutex_remove()
We have to remember to free the condvar, so add a __fio_mutex_remove()
for cases that init a mutex inside an smalloc'ed region with
__fio_mutex_init().

Rework lockfile= file lock handling
Get rid of the hand rolled rw semaphores, just use pthread
rwlocks instead. Kill the batching too, it was broken by
default, so nobody could have been using it.

Switch mutex to using anonymous mmap
We don't need an fd backing for this, saves on file descriptors
in use.

Revamp file locking
Get rid of the semaphore implementation, no need to carry both.
Add different locking modes (exclusive and readwrite) to enable
a wider range of testing. Also combine lockfile and lockfile_batch,
the latter is now a postfix option to the former.
So to enable readers-excluding-writers locking mode with a lock batch
count of 4, you would write:
lockfile=readwrite:4
instead.

Shrink the semaphores a little
The downside is that they hold the fd open, so it steals one
possible file open per-file. Will fix that in the next commit.

Add a real semaphore implemtation
I've seen races where job N+1 got started before N, this breaks
for dependent jobs. So give up and implement a real semaphore
in mmap'ed shared storage.
