This makes the amr demuxer support seeking, closing roundup
issue 2593.

Previously, the field pointed to the second byte of the packet
(which is the first byte of the actual AMR payload).

This allows libavformat to guess an estimated duration for
amr files.

For streams with varying bit rates (or with silence descriptors
or "no frame" blocks) the guess is, of course, inaccurate.

According to the RFC, the default is multicast if nothing is
specified, which doesn't make sense for TCP.

According to a bug report, some Axis camera models give a
"400 Bad Request" error if this is omitted.

A similar variable for the total stream duration was changed to
int64_t in b79c3df0, due to overflows in some odd

Also reset coded_block at each new slice, fixes problems in slice playback.

Introduce end: and err: labels at the end of vc1_decode_frame(), which

It's an evil hack that assumes an AVIOContext is always based on top of
an URLContext.
It's also not used anywhere.

Remove usage of tcgetattr and tcsetattr to modify terminal
parameters, and rely on ctrl-c to stop instead of pressing 'q'.
On systems with conio.h, keep the old behavior.

Changing the terminal settings causes problems if multiple instances
are running asynchronously on the same terminal, such as during a
parallel FATE run, or if the process crashes before restoring the
terminal.  In both cases, the terminal state is messed up requiring
a manual reset.

Change "file:stream[:syncfile:syncstream]" to
"file.stream[:syncfile.syncstream]", the latter syntax is more
consistent with the stream identifier form printed by
av_dump_format(), and more readable. Both syntaxes are currently
accepted by the opt_map() code.

and use in scale_coefficients() for the floating-point AC-3 encoder.

This updates the seek test reference to match de11ee90.  Before this
change, most of the seeks requested positions before the supposed
start of the file (the preroll time), resulting in the first packet
being returned.  With the preroll subtracted, some of these seeks
will land within the file and some beyond the end, thus returning
a different set of packets.
