The global header is not explicitly required for playback, and
omitting it allows for simple concatenation.

mjpegdec: apply flipping after decoding, not before
This is simpler and removes a silly restriction on edges being present.

hevc: fix decoding of one PU wide files
For those the block size may be larger than the source linesize (if the
edges are not allocated).

vp9: drop support for real (non-emulated) edges
They are not measurably faster on x86, they might be somewhat faster on
other platforms due to missing emu edge SIMD, but the gain is not large
enough to justify the added complexity.
