9a71e969b5 remote: slightly improve debugging of socket selection
The current debug message reports the "mode" after selection has
completed, however, the "mode" value can be changed by the selection
logic. It is thus beneficial to report most values upfront, and only
report newly changed values at the end.

f8ec7c842d rpc: use new virt-ssh-helper binary for remote tunnelling
This wires up support for using the new virt-ssh-helper binary with the ssh,
libssh and libssh2 protocols.

The new binary will be used preferentially if it is available in $PATH,
otherwise we fall back to traditional netcat.

The "proxy" URI parameter can be used to force use of netcat e.g.

  qemu+ssh://host/system?proxy=netcat

or the disable fallback e.g.

  qemu+ssh://host/system?proxy=native

With use of virt-ssh-helper, we can now support remote session URIs

  qemu+ssh://host/session

and this will only use virt-ssh-helper, with no fallback. This also lets
the libvirtd process be auto-started, and connect directly to the
modular daemons, avoiding use of virtproxyd back-compat tunnelling.

1ba30bc1e5 remote: extract logic for determining daemon to connect to
We'll shortly want to reuse code for determining whether to connect to
the system or session daemon from places outside the remote driver
client. Pulling it out into a self contained function facilitates reuse.

The remoteGetUNIXSocketHelper method will be needed by source files
beyond the remote driver client.

3dfd0cbf25 remote: parse the remote transport string earlier
We delay converting the remote transport string to enum form until
fairly late. As a result we're doing string comparisons when we
could be just doing enum comparisons.

The remoteDriverTransport and remoteDriverMode enums are going to be
needed by source files beyond the remote driver client.
