addongui: fix fallback method if addon does not provide a skin file for current skin
[WinEvents] Move win32 only code into win32 file.
[dvdplayer] fix deadlock when trying to go to disc menu
[WIN32] fixed: jenkins doesn't like the rxvt shell so use sh instead. Since sh still crashes often when compiling attended we keep using rxvt there.

fixed: addoninstaller unguarded null pointer after #2475
Only add to preDeps when it's not in there.
depends: fix sed in libgcrypt which wants to change the optimisation but also might change other stuff we don't want (e.x. XBMC-OSX to XBMC-O1SX :p)

[rbp/omxplayer] sync up with dvdplayer master changes
[rbp] Check free memory, and if plenty use full size buffers for reading files

omxplayer has used a quarter sized video buffer and a half sized audio buffer for the file reading message queue, compared to dvdplayer.
This is required on 256M boards, but is unneccessary on 512M board. So we query the free memory and use full size buffers if there is plenty.
Revert "[rbp] Always use the aspect ratio from file."

This reverts commit 7f5d3ede514f30552e42464c29227d570b38ed8a.
[rbp] Set mediatime on GPU after a seek.

Currently after a seek, the mediatime doesn't update until an audio and video packet have been fetched from demuxer, and been decoded. For HD content this can take a second or two.
This has a couple of undesirable effects:
The seek time that pops up after a seek initially shows the before seek time, and the file progress bar is laggy.
If you seek a second time, before the time has updated, it will use the before seek time, and the second seek has no effect.
This limits a sequence of seeks to a maximum of about 1 every second or two.

The fix udpates the GPU mediatime immediately after the seek, so the mediatime is correct immediately which fixes the undesirable behaviour.
Add reporting of fifo fullness for use with hdmi_status_show
that stops the stray message entering the Q, which causes it to
immediately try and go normal speed when it should be buffering.

Strictly this is not quite right, it then results in some Put() calls
to the Q befores its init'd, but its those messages that caused the
initial (wrong) set speed etc... Really it needs fixing properly, but
this at least brings omxplayer into line with the other players.
Expose GetAudioRenderingLatency
Add OMXLateCount to query if packets have arrived late
Add more debug logging
