08bebeb1be Revert "all: Don't set AVClass.item_name to its default value"
Some callers assume that item_name is always set, so this may be
considered an API break.

This reverts commit 0c6203c97a99f69dbaa6e4011d48c331e1111f5e.

0c6203c97a all: Don't set AVClass.item_name to its default value
Unnecessary since acf63d5350adeae551d412db699f8ca03f7e76b9;
also avoids relocations.

ffc1208266 lavf/prompeg: prompeg_write() must report data all was written
Previously, prompeg_write() would only report to caller that bytes we
written when a FEC packet was actually created.  Not all RTP packets are
expected to generate a FEC packet however, so this behavior was causing
avio to retry writing the RTP packet, eventually forcing the FEC state
machine to send a FEC packet erroneously (and so breaking out of the
retry loop).

This was resulting in incorrect FEC data being generated, and far too
many FEC packets to be sent (~100% FEC overhead).

fix #7863
