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.

781e61d569 omxvideoenc: Drop EOS events in ::finish() 
The event will be forwarded downstream from the srcpad
loop function after the last buffer was generated by the
component. Forwarding it after ::finish() will use the
sinkpad streaming thread and does not guarantee that
the encoder is completely drained.

879349ba11 omxvideoenc: Set force_keyframe to FALSE after handling it 
There's no reason why the base class should forward the event
further downstream if we already handled it and will insert a
keyframe.

or to handle some frames differently than the default behaviour.

fb5d700ec9 omxvideoenc: Release the video codec stream lock before acquiring an input buffer 
Otherwise the srcpad task might block on this lock and
no buffers ever become available again.

2d6239678f omxvideoenc: Don't try to drain the component after EOS 
And don't send EOS twice in any case. This most likely
will cause the component to not output it again and
is not necessary anyway.
