kaitoast: fix deadlock caused by grabbing the gfx lock while other locks...
[3D] Support switching to 3D resolutions

Include matching 3D flags (SBS/TAB) in the score of a resolution to switch to, to enable switching to 3d modes.
Also remove the old code that treated 3D modes differently when assigning a score.

I've also added a small weight to higher multiples of the desired framerate, so if display supports 30, 60 and 120Hz
and the video is 30fps then 30 will now be chosen rather than 120. This reduces the overhead of rendering the gui.
[confluence] Use animated gif as a cheaper working spinner
[rbp/omxplayer] Do we need discontinuity handling?

So far I've not seen what this is needed for and it does cause problems for some files.
h264_parser: Initialize the h264dsp context in the parser as well

Each AVStream struct for an H.264 elementary stream actually has two
copies of the H264DSPContext struct (and in fact all the other members
of H264Context as well):

((H264Context *) ((AVStream *)st)->codec->priv_data)->h264dsp
((H264Context *) ((AVStream *)st)->parser->priv_data)->h264dsp

but only the first of these was actually being initialised. This
prevented the addition of platform-specific implementations of
parser-related functions.

h264dsp: Factorize code into a new function, h264_find_start_code_candidate

This performs the start code search which was previously part of
h264_find_frame_end() - the most CPU intensive part of the function.

By itself, this results in a performance regression:
              Before          After
              Mean   StdDev   Mean   StdDev  Change
Overall time  2925.6 26.2     3068.5 31.7    -4.7%

but this can more than be made up for by platform-optimised
implementations of the function.

In combination with the preceding patch:

[rbp/omxplayer] Avoid clipping with amplification
[rbp/omxplayer] Fix stall on seek with deinterlace

Need to flush image_fx input port when seeking - this got lost in #3397
[rbp/omxplayer] Add high level locking to OMXVideo

Finally tracked down the long term bug where channel changes sometimes just produce a black screen.
When changing channel we get a couple of open/close cycles as parameters in the hints get updated (e.g. video profile/level)
These are interleaved with decoding of frames from a different thread.
If the components are shut down while a packet is being submitted, we naturally get an OMX error, and playback stalls until another channel change.

OMXAudio already uses a critical section lock. OMXVideo should also do too.
