avio: introduce an AVIOContext.seekable field

Use it instead of url_is_streamed and AVIOContext.is_streamed.

flvdec: read index stored in the 'keyframes' tag.

'keyframes' metatag is not part of the standard, it is just
convention to use such kind of metatag information for indexing.
Structure is following, it allows to have it inconsistent:

Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice.

This also lists the objects from those two libraries as internal (by adding
the ff_ prefix) so that they can then be hidden via linker scripts.

Use all 32 bits of the timestamp when calculating flv duration.
At the moment, duration is mainly set from the metadata packet. If that is not
available, the fallback is checking the low 24 bits of the last packet. This is
not enough for files over 4,6 hours in length, so read all 32 bits instead....
