Why on earth the hardware returns garbage for the first sample of
a decoded picture is anyone's guess. The simplest reasonable way
to patch it up is to copy the first sample of the second line. This
should result in the correct chroma values (because the data was
original 4:2:0 upsampled to 4:2:2) even if the luma is isn't.
This avoids potential rounding errors and guarantees the source aspect
ratio is preserved.
Keep writing pixel values when Stereo 3D Mode is enabled and for WebM,
as the format doesn't support anything else.
This fixes ticket #5743, implementing the suggestion from ticket #5903.

If there are no index entries, e_old = st->index_entries is only one
byte large, since it was created by av_realloc called with size 0.
Thus accessing e_old[0].timestamp causes a heap buffer overflow.

Merged as-at libav 398f015, and therefore includes outstanding
skipped merges 04b17ff and 130e1f1.
All features not in libav are preserved, and no options change.
pkg-config(1) expects uninstalled pc files to follow the
blah-uninstalled.pc naming convention and the behavior
of the program is impacted by it. Without this fix
overriding PKGP_CONFIG_LIBDIR is required to ensure
uninstalled files are preferred (overkill), instead of
just adding pc-uninstalled/ to the utility's search path
by setting PKG_CONFIG_PATH accordingly.
