lavcodec: Adding support for End Trimming in Opus encoder

Adds the end trimming value (duration to be trimmed from the end
of the file due to padding) to the packet's side data. This is
then made use by the muxer to put the value in the container.

lavf/matroska: Adding support for Opus CodecDelay

In order to represent the codec delay accurately in Matroska, a
new element CodecDelay has been introduced. It contains the
overall delay added by the codec in nanoseconds. This patch adds
support for muxing CodecDelay value in the container.

opus/matroska: Adding support for DiscardPadding in muxer

Support for end trimming Opus in Matroska is implemented by using
the DiscardPadding container element in the Block data. The last
chunk is stored as a Block instead of SimpleBlock and the
trimming information is stored and used to discard samples that
were padded by the Opus codec. This patch adds support for muxing
DiscardPadding element into the container with appropriate value.

Note on lavf/matroskaenc: no extra subtitles.o Makefile dependency is
added because only the header is required for ff_subtitles_next_line().

Note on lavf/mpsubdec: code gets slightly complex to avoid an infinite
