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.

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.

766f5bd161 omxaudioenc: Don't forward EOS events immediately but let all other events be handled by the base class

05e4b48855 omxaudioenc: Improve EOS handling 
If downstream return UNEXPECTED we should still signal the
drain cond because nothing will trigger this again later.

b45197c0d7 omxaudioenc: Release the audio encoder stream lock before acquiring an input buffer

no buffers ever become available again.

17d0751887 omxaudioenc: 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.
