base: genlock: Properly destroy handle resources

The resources allocated for a handle were not being freed on device
release.  This included releasing the lock.  Unfortunately, the
lock release had a fput() too many which was screwing up the
reference counting on the file descriptors.  When attaching a lock,
we only need the file pointer for a short time so fput() it back
immediately.  That way, only there will only be one reference to
the lock per process, and the process will be responsible for
closing the fd directly and the fput() in genlock_release_lock
is no longer needed.

base: genlock: Avoid a race condition when releasing locks

Avoid a race condition if a lock gets released by all owners
but a process fails to close a lock file descriptor and tries
to reuse it.  Clearing the pointers to the data will ensure
that attaching a dead lock will return an error.

base: genlock: Check for instances where handle is NULL

Check for the possibility of NULL handles passed into the
in-kernel API functions and return error where appropriate.
There is a non-zero chance that the private_data will be
cleared while the FD is still active, so check in the ioctl()
function as well.

base: genlock: Remove genlock_release_lock and associated ioctl

Allowing a lock to be asynchronously released while a handle
was still active turned out to be too dangerous to use in a
multi-threaded environment and it served no pratical
purpose anyway.  Handles now hold an attached lock until they
are destroyed.

base: genlock: Use a signed long for the result from wait_timeout

interruptible_wait_timeout returns a signed long, so make sure that
we use a signed long to hold the result. Using an unsigned value would
horribly misinterpet an error such as -ERESTARTSYS.

base: genlock: allow synchronization with a single gralloc handle

In order to support synchronization in a process with a single
gralloc handle we require the ability to write lock a buffer
while it is already read locked by the same handle. This change
extends the concept of an exclusive write lock or recursive read
locks to a genlock handle (rather than the genlock lock).
Genlock cannot provide deadlock protection because the same
handle can be used simultaneously by a producer and consumer.
In practice an error will still be generated when the timeout
expires.
