int ff_http_averror(int status_code, int default_averror)

This helper function returns AVERROR_ value from 3-digit HTTP status
code.

Second argument, default_averror, is used if no specific AVERROR_ is
available. It is introduced because in different places of code
different return codes are used - -1, AVERROR(EIO), AVERROR_INVALIDDATA.

For URLs "rtmp://server[:port]/foo" determine what `foo` refers to. If
application name has been defined by the user assume that `foo` is a
playpath, otherwise assume application name.

This allows restricting demuxers to a list of needed ones for improved security
Note, some demuxers themselfs open other demuxers, these are only restricted if
AVOptions are forwarded to them. Please check that your code does that.

This is similar to 20a5956b

The difference this change makes affects only rather few files
but looks like:
Stream #0:1: Video: mjpeg, 90k tbr, 90k tbn, 90k tbc
vs.
Stream #0:1: Video: mjpeg, none(bt470bg/unknown/unknown), 90k tbr, 90k tbn, 90k tbc
