This reverts commit 32ce763b.

This forces Lua RC to exit cleanly in all cases.

When calling vlc_va_Get() failed inside ffmpeg_GetFrameBuf(), then
the error messages says "vaGrabSurface failed" however it should
say "vlc_va_Get failed". Since hw accelerators are called through a
vlc abstraction defined in va.h. It originated from libva (VAAPI),
but it includes VDPAU and DXVA2 now.

Keep atleast 3 * seglen amount of segments in playlist if possible.
This will cause playlist to increase sometimes over i_numseg, but it
follows the draft better.

livehttp: try to comply draft 11 section 6.2.2 for how long to keep segments around in sliding window

This seems buggy in libavcodec

So far rawvideo assumed that the full pitch was part of the picture.

The target thread has no defined cancellation points, so simply remove
the vlc_cancel() call. (Adding vlc_savecancel() would work to the same
effects, but with extra code.)

The cancellation-safe section was protected instead of the
cancellation-unsafe section.

This fixes the corner where the username or the password contains @
(although encoding would probably be a better idea).

VLC main() initializes the values too late for interfaces and playlist.

This should fix ISDB-S tuning.
