933dec0e29 file: Add an option for following a file that is being written
Using this requires setting the rw_timeout option to make it
terminate, alternatively using the interrupt callback (if used via
the API).

This commit also disables the async fate test, because it
used internal APIs in a non-kosher way, which no longer
exists.

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.
