The new option allows to select the starting show mode.

Also rename VideoState->show_audio to show_mode.
Improve readability.

Move up the definition of audio_write_get_buf_size(), so that it is
defined before it is used. Simplify.

When CONFIG_AVFILTER, use a AVFrame -> AVPicture cast rather than
explicitely copy the image information from AVFrame to a new
AVPicture.

Stop the avio input at a point where amf_parse_object can
continue parsing the end of the object seamlessly, when all
data is available.

If unsupported data is encountered within the keyframes object,
try seeking to the start of the keyframes object - if the seek
back was successful, the caller can continue parsing the rest
of the AMF data.

Current keyframes data parser unconditionally rewind metadata to
the end at the end of function. As result ALL metadata located
after keyframes index not parsed, and as metadata object can have
ANY placement inside metadata it can lead to unpredictable result
(bitrate can not be found, etc.). As result FLV movie will not
play at all in such situation.

Spotted by Reimar.

(1<<31) is undefined and seems to be evaluated by gcc to -2^31 when
these formulae require 2^31.

These conversions still need fate tests.

According to ISO 9899:1999 S 6.5.7/4:

The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits
are filled with zeros. If E1 has an unsigned type, the value of the
result is E1× 2^E2, reduced modulo one more than the maximum value
representable in the result type. If E1 has a signed type and
nonnegative value, and E1× 2^E2 is representable in the result type, then
that is the resulting value; otherwise, the behavior is undefined.
