lavfi: name anonymous structs
filtfmts: remove unused lavf include
utils: add yvyu422 to avcodec_align_dimensions2
h264: codec reinit: remove statements without effect

avctx->coded_{height,width} will always equal h->{height,width} since
init_dimensions() does that explicitly, Size changes are detected by
changes in mb_{height,width} earlier and propagated through the
needs_reinit variable.

fate: add tests for SGI RLE and MVC1&2 decoders
mvc: Specify the pixel format for the mv-mvc* tests

Also set the RGBA pixel format correctly as the native endian format,
which is what it returns.

This fixes the tests on big endian.

display transformation api

Add AV_PKT_DATA_DISPLAYMATRIX and AV_FRAME_DATA_DISPLAYMATRIX as stream and
frame side data (respectively) to describe a display transformation matrix
for linear transformation operations on the decoded video.

Add APIs to easily access values such as rotation angle, and to convert rotation
angles to matrix.
mov: save the display matrix to extract transformation operations
h264: parse display orientation SEI message
wip: new things api rot
h264 wip
hevc: parse display orientation SEI message
vf_showinfo: print display transformation values
lavf: group dump functions together
lavf: dump side data when probing
