Since the av_malloc() may fail and return NULL pointer,
it is needed that the 's->edge_emu_buffer' should be checked
whether the new allocation is success.

Clear anything that av_hwframe_map() might have done to the destination
frame, but leave caller-provided fields unchanged.

Reduce some asserts by default.

Makes an auto-growing FIFO and performs a sequence of randomly-sized
writes/peeks/reads.

When the fifo is grown by exactly the current write offset, it would end
up with offset_w = nb_elems. If av_fifo_write_from_cb() is called in
such a state, the user callback would get callled with *nb_elems=0,
which will then cause the write to return without writing anything.

Current code will loop forever if MFXVideoVPP_Init() fails.
Also, simplify the code.

It was only used by XvMC.

It is no longer used for anything.

XvMC was last relevant over 10 years ago, if ever. There is no reason to
use it today.

The ID3v2.4.0 standard defines TIT1 as the "Content group description"
tag [1]. This frame is usually referred to as the "Grouping" tag and in
de-facto use under that name by Vorbis and APEv2 [2].

This commit introduces a mapping from "TIT1" to "grouping" in the
id3v2.4 metadata conversion table. This will enable software to access
it using that name. In particular, MPD will now read this tag correctly
when using the ffmpeg decoder plugin.
