Splits at borders of cells are invalid, since it leaves one of the
cells with a width/height of zero. Also, propagate errors on buffer
allocation failures, so we don't continue decoding (which crashes).

Provide a way to wrap around the segment index so pseudostreaming
live through a web server and html5 browser is simpler.

Also ensure that 0 (disable) is a valid value across the options
providing wrap around.

WavPack has a comprehensive test suite, and a bunch
of corner cases.

The index validation identifies these indexes as broken.

By validating the index entries while reading, we don't need to
seek at startup to validate the entries. If the error in the
index entries is not pointing to (our definition of) the start
of packets, and there is an index entry pointing at some of the
first packets after the metadata, the invalid index can be discarded
almost immediately.

This returns 200 OK for OPTIONS requests and 501 Not Implemented
for all other requests.

Even though this doesn't do much actual handling of the requests,
it makes the code properly identify server requests as such, instead
of interpreting it as a reply to the client's request as it did
before.

For encoding, AVCodecContext.frame_size is the number of input samples to
send to the encoder and does not necessarily correspond directly to the
timestamps of the output packets.

Put related fields together, move the important ones closer to the
beginning, try to eliminate holes.

Neither of those is guaranteed to be connected to framerate in any way
(if it even exists).

Fixes bug 56.

Because in contrast to the decoder, the parser does not setup low_delay.
The code in parse_nal_units would always end up setting has_b_frames
to "1", except when stream is explicitly marked as low delay.
Since the parser itself would create 'extradata', simply reopening
the parser would cause this.

This happens for instance in estimate_timings_from_pts(), which causes the
parser to be reopened on the same stream.

This fixes Libav #22 and FFmpeg (trac) #360

It's not supposed to be set outside of lavc.

r_frame_rate should in theory have something to do with input framerate,
but in practice it is often made up from thin air by lavf. So unless we
are targeting a constant output framerate, it's better to just use input
stream timebase.

No functional changes, just make it more readable.

No changes in the test results.

It is not allowed to change mid-stream like it does currently. Instead we need
to buffer the first 8 frames before returning them as a single packet, then
only return single frame packets after that.
