This allows -print_format to accept string of the form WRITER=OPTIONS,
as required by the pending compact writer patch.

Also update documentation related to the output format.

The new provided API is more flexible and is decoupled from the
application level code, so it is easier to maintain.

On the first iteration through this code, last_dts is always
INT64_MIN (AV_NOPTS_VALUE) and the subtraction overflows in
an invalid manner.  Although the result is only used if the
input values are valid, performing the subtraction is still
not allowed in a strict environment.

In addition to avoiding undefined behaviour, an unsigned type
makes more sense for packing multiple 8-bit values.

Since nnz can be zero, this is needed to avoid a shift by 32.

    ffmpeg: replace -vcodec/-acodec/-scodec with a better system.

    The new option doesn't depend on its placement wrt -new* options (which
    don't exist anymore) and works in a similar way as per-stream AVOptions.

    -[vas]codec remain as aliases to -codec:[vas]

ffmpeg: avoid multiple redundant av_gettime() calls, rather reuse the value in a iteration of the main loop.
