It was deprecated only recently.

AVOptions were moved to libavutil only recently.

The current value is masking the POSIX error code EPIPE, which has a
different semantics.

This breaks API.

AVERROR_NUMEXPECTED is used only in the image muxer and demuxer, and
has a too much specific meaning, which is better explained through a
log message. Thus it can be replaced by AVERROR(EINVAL).

This breaks API.

The new error code is better than AVERROR(ENOENT), which has a
completely different semantics ("No such file or directory").

This makes seek_test to be rebuilt when its dependencies
has changed. The changes to the dependencies didn't usually matter
in practice, but the introduction of side data in AVPacket required
a recompilation.

instead of unconditionally at the start of the function.

This fixes a bug where a successful call to ff_thread_init() masks errors that
occur after that point in the function.  It also makes future bugs like this
less likely since the error code is now set near to the point in the code
where the error is found.

Fixes make install after 3453a231.

The problem with url_exist() is that it tries to open a resource in
RDONLY mode. If the file is a FIFO and there is already a reading
client, the open() call will hang.

By using avio_check() with access mode of 0, the second reading
process will check if the file exists without attempting to open it,
thus avoiding the lock.

Fix issue #1663.

Make AVIO_FLAG_ access constants work as flags, and in particular fix
the behavior of functions (such as avio_check()) which expect them to
be flags rather than modes.

This breaks API.
