Switch to SOCK_STREAM for the CMD_SET_DATAFD socketpair where the one
end is passed to swtpm to test that this type of socket will cause
automatic termination of swtpm when the connection is lost. This is also
the socket type that QEMU uses.

Use the send1msg() ot the twisted sendmsg package since sendmsg()
is only supported in more recent versions of twisted.
Following this we also don't need to install a recent version of twisted
via pip on Travis, which runs Ubuntu 14.04.

Rather than sending two separate messages with the bare python 2
API, use the python twisted package to send the control and data
in one sendmsg() call. This avoids occasional test failures in
the ctrlchannel test case that is currently sending the data and
control part of the message in 2 steps, which can lead to the
recpient not seeing the whole message.
Add python-twisted as a build dependency to the rpm and Debian
builds and the .travis.yml.

As objected by QEMU upstream developers to use two different sockets for
starting/using of swtpm, This commit adds support for passing unix domain
socket over control channel.
The summary of the changes include:
- Defined new control command CMD_SET_DATAFD, using this clients can send data
socket.
- set mlp.fd and mlp.flags outside of the mainloop
- updated the testcases
