mux: fix chunked interleaver

The code did not account properly for packets that where added to
the end of the packet list. Also flags for such packets where not
set correctly leading to incorrect chunked interleaving.

mux/chunked interleaver: better align duration chunks.

This code causes the chunking to tend toward more optimal
alignment between streams.
The first chunks can still be less optimal aligned
Make the latm decoder less verbose on initialisation.

Only skip MLP header in mpeg files if the codec actually is MLP.

theora: Skip zero-sized headers

This fixes a regression since d9cf5f51 with theora over RTP
(possibly with other variants of theora as well).

In theora over RTP, the second of the 3 headers turns out to be
0 bytes long, which prior to d9cf5f51 worked just fine. After
d9cf5f51, reading from the bitstream reader fails (since the reader
wasn't initialized but returned an error if initialized with 0 bits).

Add a new function av_codec_get_tag2().

av_codec_get_tag() may return 0 both in case a codec_tag was
found and if no codec_tag was found.
The new function does not have this ambiguity.
Use new function av_codec_get_tag2() in ffmpeg.c.

Fixes ticket #1953.
