08bebeb1be Revert "all: Don't set AVClass.item_name to its default value"
Some callers assume that item_name is always set, so this may be
considered an API break.

This reverts commit 0c6203c97a.

0c6203c97a all: Don't set AVClass.item_name to its default value
Unnecessary since acf63d5350adeae551d412db699f8ca03f7e76b9;
also avoids relocations.

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.

a8f171151f file: Add 'blocksize' option
Interruptibility of file operations is strongly desirable in case of
slow storage access, e.g. mounted network share.
This commit introduces possibility to limit data quantity transferred by
'file' protocol at once. By default, old behaviour is preserved and data
is still tried to be transferred without block size limitation.

Note that file I/O operation still may block (or even freeze) inside of
single read(2) or write(2) operation.
