recode_subtitle() is called implicitly by avformat_find_stream_info().
As such, clients which disable ICONV always crash if a file contains
subtitles; even if they don't care about them.

The original code left-shifts negative values, which is undefined
in the C99 specification (the one used during normal FFmpeg compilation).
This change multiplies by (1 << shift), which is functionally equivalent,
but has defined behavior.
With this change, fate-idct8x8 compiled with --fsanitize=undefined works.

avpacket: fix copying side data in av_packet_copy_props()

this prevents the creation of a packet even though no single sample has ever
been input, which some confusion in the timestamp generation

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 functions to easily extract a rotation angle from a matrix and
conversely to setup a matrix for a given rotation angle.

Side data count is incremented by by calling av_packet_new_side_data()
in the following loop, setting it explicitly results in the resulting
value being twice what it should be.

By default, macro EPEL_FILTER loads the coefficients inconditionally
into m14/m15. This forces an unneeded higher register count.
Reduce that count by making them parameters of EPEL_FILTER.
