This reverts commit 7d3c30f9.

As specified in the MSDN documentation
It will warn, though

This is way cleaner and should help supporting deinterlacing without
memcpying full images (hopefully)

This patch makes volume more consistent with the rest of vlc :
 - volume is now advertised on a 0-400% range instead of a misleading
   0-100% range. This fixes the discrepancy between volume displayed
   within the skins and volume displayed via OSD
 - "qt-volume-complete" and "volume-step" are now taken into account,
   which makes skins2 more consistent with qt4

Also, remove leftover _intel parts here and there.

This is equivalent and better supported on Mingw
And, remove an outdated comment
