'struct AVClass' is used in the code since
641c7afe3c17334b81e3e2eef88f1751eb68f89f, but AVClass is typedeffed as
an anonymous struct.

Yet another option half implemented, more will follow...

Initial test code, the filename isn't yet guessed and the file index
isn't printed yet.

This had been the fix used by Michael Niedermayer to solve the
ratecontrol convergence issue.

Just for naming consistency, no functional changes.

Split actual writing to read_number() in the same way as write_number().
Allows set_string_number() to write to a caller-provided destination.

New functions can get values from child objects, properly report error
codes and have consistent naming and signatures.

Deprecate av_set_*

New functions support setting values on children, return error codes
instead of options and have consistent naming and signatures.

This will allow the caller to enumerate child contexts in a generic way
and since the API is recursive, it also allows for deeper nesting (e.g.
AVFormatContext->AVIOContext->URLContext)

This will also allow the new setting/reading API to transparently apply
to children contexts.

No application rely on this count being correct as far as
I know, but if we write a nonzero count value, it might just
as well be the right one.

DSS enables this automatically if streaming VOD over TCP. If
enabled, the server feeds packets faster than realtime, screwing
up RTCP NTP based timestamps.

Also, DSS doesn't indicate that this was indicated, if it was
enabled automatically (although if it was requested to be enabled,
a header saying that it was enabled is added, but this isn't
added if it is enabled automatically), making it even harder
to detect and work around properly without explicitly asking
for it to be disabled(/enabled, if we were able to support it).

Unsupported bit depth is certainly an error the user will
want to know about.

This allows skipping past unsupported RTCP packet types, as
RFC 3550 section 6.1 mandates.

Currently this only has any practical effect if a sender puts
an unrecognized type before RTCP_BYE in a compounded packet, or
(incorrectly) does not put RTCP_SR first.

We actually read 20 bytes of these packets.

This code relies on the result wrapping as for unsigned
values, and the sign is not used.  Thus an unsigned type
is proper here.

This avoids writing these entries doubly if transcoding from
flv to flv, since the muxer blindly writes any and all metadata
keys set, in addition to the fixed fields that the muxer
always writes.
