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.

This allows the chained demuxer (or more precisely, the lavf
utility code) to better fill in timestamps on packets from
these, especially for cases where one stream is a raw ADTS
stream.
