Michal Privoznik d133d73f54 remote: Pass 'mode' and 'socket' URI parameters to virt-ssh-helper
When handling virConnectOpen(), we parse given URI, specifically
all those parameters we know, like ?mode, ?socket, ?name, etc.
ignoring those we don't recognize yet. Then, we reconstruct the
URI back, but ignoring all parameters we've parsed. In other
words:

  qemu:///system?mode=legacy&foo=bar

becomes:

  qemu:///system?foo=bar

The reconstructed URI is then passed to the corresponding driver
(QEMU in our example) with intent of it parsing parameters
further (or just ignoring them). But for some transport modes,
where virt-ssh-helper is ran on the remote host (libssh, libssh2,
ssh) we need to pass ?mode and ?socket parameters, so that it can
do the right thing, e.g. for 'mode=legacy' start the monolithic
daemon, or for 'socket=' connect to the given socket.
