Conflicts:

Only libtwolame changes, as the forcing of a sample rate was not merged for the native mp2 encoder

If 384k is too high for the samplerate, choose the closest
possible

Idea to increase the bitrate from: 46439e15Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

The default should be not to resample.

ffurl_seek() will not work even when it should be a no-op, so do not
call it on crypto protocol.

Also replace use of ffurl_size() for the same reason.

This causes us to favor RGB8 over PAL8 when FF_LOSS_COLORQUANT is used

It probably makes sense to reinvestigate the exact scoring of pal8 when
our pal8 support improves to be supperior to rgb8
