[rbp/omxplayer] Remove unused state from OMXClock

m_has_audio/m_has_video are always set before OMXReset is called, so just make them local parameters.
m_video_start and m_audio_start are unused, so remove them.

This commit should have no functional change

[rbp/omxplayer] Remove unused state from OMXClock
[WIN32] fixed: if we don't found - for whatever reason - a suitable monitor, abort early and write the reason into the log file.
[WIN32] fixed: use .empty() instead of .size() < 1 (grr)
[rbp/omxplayer] Support ff/rew

Big missing feature added for Pi.
It works by increasing the clock and discarding audio when at 2x and 4x.
For rewind and 8x and higher, it uses a different scheme. It pauses video, and single steps.

For both schemes it uses the normal dvd player mechanism of seeking when the clock has diverged by too much.

Notes:
dvdplayer still decodes (then discards) audio when ff/rew.
I'm skipping the decode step (too much cpu at 4x realtime).

I've made GetTime return m_clock.GetClock() when ff/rew. (m_State.time is too jumpy).
