Since global options are processed before all the other options now, we
do not have to try creating the complex filtergraphs several times
anymore, it is enough to do it once after the input files are opened.

It is a better place for it, there is no reason to wait until
transcode_init().

Also, drop the now unused cmdutils_read_file(). There is no reason to
have two functions doing essentially the same thing.

It more logically belongs there.

This will be useful in the following commits.

There is only one decoder left that supports this (libopus, which is not
used by default since we have a native one) and this code goes against
the avconv design, since it propagates information back from the encoder
to decoder.
