72fa93956b omx: Remove QCOM hack to reset nOffset in EmptyBufferDone 
This is now done in a generic way that does not require any
hacks because it will work without any side effects on any
OMX implementation.

2750a8869b omx: Reset nOffset to 0 in EmptyBufferDone if nFilledLen is 0 
Some OMX implementations don't reset nOffset when the complete
buffer is emptied but instead only reset nFilledLen. We reset
nOffset to 0 if nFilledLen == 0, which is safe to do because
the offset *must* be 0 if the buffer is not filled at all.

Seen in QCOM's OMX implementation.

f0fe1148b7 omx: Wait until the Executing state is reached before calling OMX_FillThisBuffer()

FTB after setting the new state and before reaching it.

9eb39ceef2 omxvideoenc: Release basevideocodec stream lock while waiting for a buffer 
This prevents deadlocks if no empty input buffers are available and
releasing input buffers requires the loop function to handle some
output buffers first.

b673e37546 basevideoencoder: Proxy the width/height/framerate/PAR constraints of downstream caps to upstream 
This allows to specify constraints on the compressed downstream caps
by muxers or capsfilters, which will then be forwarded to upstream
and allows video converters to fulfill the constraints.

Code based on Mark Nauwelaerts audio encoder base class.
