The interrupt callback has to be passed in during opening (setting it
after opening isn't enough), since a blocking open couldn't be
interrupted otherwise.

Options are passed down to procotols and also need to be available
during open() in most cases.

Not used anywhere yet, support for passing options from avio_open() will
follow.

There are a few more cases of chained demuxers, but they
only use custom IO which don't do any blocking IO and thus
don't need the callback.

Change all uses of these function to pass the relevant
callback on.

This is a better io interrupt callback function, which has an
opaque parameter, which is given to the interrupt callback.

This allows callers to precisely cancel IO for one single
AVFormatContext, without interrupt other ones in the same
process.

Note, it's not needed in AVIOContext, at the moment.

It does not make much sense to factor the error handling to its own
av_always_inline function. Fixes "format not a string literal and no
format arguments" warning in the av_log.

Add a decoder for the VBLE Lossless Codec, which
still has a cult following. Used to be popular

The Musepack SV7 reference encoder converts mono to stereo when encoding.

It is already checked in avcodec_decode_audio3()

This is needed because the twinvq decoder cannot rely on bit_rate to be set.
The API documentation says that bit_rate is set by libavcodec, not by the
user.

It is a lossy codec with varying quantization, so bits_per_coded_sample is
not applicable.

Altivec does unaligned reads from this buffer in
hscale_altivec_real(), and can thus read up to 16 bytes beyond
the end of the buffer. Therefore, add an extra 16 bytes of
padding at the end of the conversion buffer.

This fixes fate-lavfi-pixfmts_scale on AltiVec-enabled builds
under valgrind.

Tested with both Basic and Digest authentication, and tested with
both proxy authentication and authentication for the requested
resource at the same time.
Signed-off-by: Martin Storsjö <martin@martin.st>

The error was hidden before, to avoid showing an error on the
first request where no auth has been provided, when the server
indicates which authentication method to use.

Now the error is printed if an authentication method was used,
but failed.

This avoids artifically consuming a partial packet but ignoring remaining data
in subsequent calls.

also move nblocks to the local scope where it is used.

The decoder already skips data at the end of the packet without this.
Also remove 2 APEContext fields that were only used for the end-of-frame
normalization.

The user could provide a larger buffer, which is already checked separately
before writing output.
