Many of these functions were named foo_free_context, and since
the functions no longer should free the context itself, only
allocated elements within it, the previous naming was slightly
misleading.

This makes it more consistent with depacketizers that don't have any
.free function at all, where the payload context is freed by the
surrounding framework. Always free the context in the surrounding
framework, having the individual depacketizers only free any data
they've specifically allocated themselves.

This is similar to how this works for demuxer/muxers/codecs - a
component shouldn't free the priv_data that the framework has
allocated for it.

This makes it clear that the individual parsing functions can't
touch the parsed out value.

This avoids implementing a full function just to set this one
field.

Use it for logging, instead of NULL or the stream codec context.

This gets rid of almost all the codec specific details from the
generic rtpdec code.

This makes the returned data valid to stream copy into other
containers as well, not only for decoding straight away.

This allows depacketizers to figure out if packets have been lost.

Fixes CID700204.

This avoids exposing a dummy AVStream which won't get any data
and which will make avformat_find_stream_info wait for info about
this stream.

All current usages of it are incompatible with localization.
For example strcasecmp("i", "I") != 0 is possible, but would
break many of the places where it is used.

Instead use our own implementations that always treat the data
as ASCII.

This avoids clashes if we internally want to override the global
open function.

This is useful for other future RTP depacketizers

It will be used by other parts of lavf now. This reverts svn rev 23846.
