This should be the most efficient version, yet.

We create a memfd buffer which we write to and later copy the output to
the heap. This also reduces the amount of callbacks that we have to pass
around.

Signed-off-by: Michael Tremer <michael.tremer@ipfire.org>

pty: Refactor forwarding

This should make the process slightly more efficient because we are
checking if there is anything in the buffers before entering the loop.
We also handle any return values from the read()/write() calls better so
that we won't continue to loop too often.
