a42f27547d omx: Implement new approach for locking that should solve all deadlocks on RPi 
No mutex is locked while calling any OpenMAX functions anymore
and everything from the OpenMAX callbacks is inserted into a message
queue and handled from outside the callbacks.

Also there's only a single mutex and condition variable per component
now for handling anything from OpenMAX callbacks and a single mutex
for keeping our component/port state sane.

e026926951 omx: Fix another race condition in the recursive mutex 
Between lock() and begin_recursion() it was possible for another thread to
try to do a recursive_lock(). This would block because the mutex was already
locked(), but not ready for recursive locking yet. unlock() would never
happen in the original thread because it was waiting for the other thread
to finish first.

Happened on the Raspberry Pi.

158775f497 Implement a new custom recursive mutex type and fix locking in callbacks so that in-context calls are allowed. 
According to the OMX specification, implementations are allowed to call
callbacks in the context of their function calls. However, our callbacks
take locks and this causes deadlocks if the unerlying OMX implementation
uses this kind of in-context calls.

A solution to the problem would be a recursive mutex. However, a normal
recursive mutex does not fix the problem because it is not guaranteed
that the callbacks are called from the same thread. What we see in Broadcom's
implementation for example is:

- OMX_Foo is called
- OMX_Foo waits on a condition
- A callback is executed in a different thread
- When the callback returns, its calling function
  signals the condition that OMX_Foo waits on
- OMX_Foo wakes up and returns

The solution I came up with here is to take a second lock inside the callback,
but only if recursion is expected to happen. Therefore, all calls to OMX
functions are guarded by calls to gst_omx_rec_mutex_begin_recursion() / _end_recursion(),
which effectively tells the mutex that at this point we want to allow calls
to _recursive_lock() to succeed, although we are still holding the master lock.

036cd16756 omx: Fix deadlock between ending a flush and the event handler 
gst_omx_port_set_flushing() calls OMX_FillThisBuffer at the end of a flush
without releasing the port lock, and this can cause a deadlock with the
EventHandler. This patches fixes this by dropping the lock for the duration of
the fill buffer call.

766dc7c541 Enable building with Android's buildsystem 
This change adds prelimary buildsystem hooks to
build gst-omx with the Android buildsystem. Like
the rest of GStreamer's Android hooks, the process
relies on the availability of androgenizer. A tool
developed by Collabora to automatically generate
Android.mk files from within the auto* setup.

Androgenizer is currently available at:

f1bbb0f8a4 basevideodecoder: fix weird event list handling 
Get rid of weird code that copies a list manually, taking
ownership of the elements and then frees the old list. Instead,
just take over the old list entirely. (If the intent was to
reverse the list, one could use g_list_reverse() instead).

Then, push events in the list out from last to first (since they
were prepended as they came in) instead of just pushing out the
last in the list and leaking the others.
