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.
The new function is more flexible than url_exist(), as it allows to
specify which access flags to check, and does not require an explicit
open of the checked resource.

Functions interrupted by url_interrupt_cb should not be restarted.
Therefore using AVERROR(EINTR) was wrong, as it did not allow to distinguish
when the underlying system call was interrupted and actually needed to be
restarted.
This fixes roundup issues 2657 and 2659 (ffplay not exiting for streamed
content).

when writing and pressing q during encoding. Instead, check url_interrupt_cb
at the end.
Note that when a protocol is interrupted by url_interrupt_cb, some data may
be silently discarded: the protocol context is not suitable for anything
anymore.

If this flag is set, the protocol can handle URLs where the
scheme is a nested scheme such as applehttp+file: - the protocol
can handle any URL where the first segment of the nested scheme
belongs to this protocol.

Fix the GCC warning:
avio.c: In function ‘register_protocol’:
avio.c:93: warning: ‘av_register_protocol’ is deprecated (declared at avio.c:86)

The URL specification allows letters, numbers, plus, hyphen, and period
in the scheme part. The isalpha() test would allow additional characters
depending on locale settings while rejecting numbers and punctuation.

This allows extending the URLProtocol struct without breaking binary
compatibility with code compiled with older definitions of the struct.
