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.
Matroska spec for CodecDelay element can be found here:

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.
Matroska spec for the DiscardPadding element can be found here:

This makes sure the faststart vs fragmentation check works as
intended when fragmentation is enabled due to using the ismv mode.

This fixes warnings about making integers from pointers without
a cast, and avoids the theoretical case where the lower 32 bits of
the pointer would all be zero where the implicit cast wouldn't give
the right result.

When compiling with --enable-small, ripemd.o will weigh a few kilobytes less than
it used to before the previous commit.

This fixes a bunch of possible overread in avformat with the idiom p +=
strcspn(p, "\n") + 1 (strcspn() can focus on the trailing '\0' if no
'\n' is found, so the +1 leads to an overread).
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
loop in the probing since there is no more forced increment.
In particular, print the standard supported by the selected input.
Additionally, use PRIx64 everywhere when printing standards.

Some fields of the frame are changed to reflect encoder decissions like
if its a keyframe. It thus cannot be constant.
