963d4b76de avformat/concat: Remove unnecessary check
This code was written when the allocation functions used parameters of
type unsigned. This is no longer true today and therefore we only need
to check whether the multiplication of the array's size stays within
a size_t -- and this can be offloaded to av_realloc_array.

82bf41f3ab avformat: Replace ffurl_close() by ffurl_closep() where appropriate
It avoids leaving dangling pointers behind in memory.

Also remove redundant checks for whether the URLContext to be closed is
already NULL.

858db4b01f libavformat: not treat 0 as EOF
transfer_func variable passed to retry_transfer_wrapper
are h->prot->url_read and h->prot->url_write functions.
These need to return EOF or other error properly.
In case of returning >= 0, url_read/url_write is retried
until error is returned.

fab8156b2f avio: Copy URLContext generic options into child URLContexts
Since all URLContexts have the same AVOptions, such AVOptions
will be applied on the outermost context only and removed from the
dict, while they probably make sense on all contexts.

This makes sure that rw_timeout gets propagated to the innermost
URLContext (to make sure it gets passed to the tcp protocol, when
opening a http connection for instance).

Alternatively, such matching options would be kept in the dict
and only removed after the ffurl_connect call.

2758cdedfb lavf: reorganize URLProtocols
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.
