If the framebuffer hardware doesn't support double buffering in hardware, then do this in software. It will increase vout memory consumption by at least one output picture size, but will guarantee smooth subpictures in the video output.

- disable frame.pts only mp4v (seems to be bug concerning only that
  codec)
- initialize p_sys->i_hq to FF_MB_DECISION_RD if else ain't specified
  (seems like it's used uninitialised otherwise)
- set mb_lmin/mb_lmax and lmin/lmax also with qmin (ffmpeg documentation
  says lmax = qmax * FF_QP2LAMBDA) seems to help rate-control.

Qt4 - Remove QFontDialog Dependency... We don't have some CONFIG_ITEM_FONT yet... Do we have complete fontconfig support btw ?

Qt4 - Windows registry manipulation. Create the good HKEY where there should be, even if the installer didn't do it.

Fix RC compilation, and OSD from C++ code in the process.
