413f05269c omxvideoenc: Add GST_OMX_HACK_HEIGHT_MULTIPLE_16 for Rpi 
The Raspberry Pi encoder produces corrupt output unless
the input height is a multiple of 16. Add a hack that adds
zero padding when needed.

05b137a256 Add a signals-premature-eos hack for egl_render 
egl_render seems to have a bug and signals EOS before it has finished
pushing out all data; this hack simply makes acquire_buffer() wait
a bit more before signalling EOS, in case egl_render decides to spit
out some more data.

a78756c63f omx: #define OMX_SKIP64BIT on the RPi as required by their API 
Also add generic support for OMX_SKIP64BIT to gst-omx, in case other
implementations also #define that for whatever reason.

4e20116bc6 omx: Add a hack for not disabling the output port after set_format until the output format is known 
Needed on some OMX implementations, e.g. the one from Atmel. It does
not send the settings-changed event on the output port if it is
disabled.

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.

9e4cddee7e omxvideodec: Add hack for Ducati components not returning from drain 
This happens on the Galaxy Nexus, and causes the pipeline to hang waiting
endlessly for a drain. The hack replaces the wait with a wait + 500ms timeout.
