It avoids leaving dangling pointers behind in memory.
Also remove redundant checks for whether the URLContext to be closed is
already NULL.

Instead of a linked list constructed at av_register_all(), store them
in a constant array of pointers.
Since no registration is necessary now, this removes some global state
from lavf. This will also allow the urlprotocol layer caller to limit
the available protocols in a simple and flexible way in the following
commits.
This definition is in two files, since the definitions will move
to the private header at the next bump.

This simplifies the open functions by avoiding one function
call that needs error checking, reducing the amount of
extra bulk code.

There is no need to write two HTTP newlines (\r\n) into "headers",
because http_connect (in http.c) already appends one HTTP newline at
the end of the given headers chunk, which would result in sending
three HTTP newlines after the headers. Most of the time it's okay
(although not RFC-conforming), but many proxy servers and the
occasional strict httpd will puke with a "400 bad request".
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.
This also lists the objects from those two libraries as internal (by adding
the ff_ prefix) so that they can then be hidden via linker scripts.
(cherry picked from commit c6610a216e)
current code wouldn't always error out on errors.
