This patch adds a glue layer to enable using libssh2 code with the
network client code.
As in the original client implementation, shell code is sent to the
server to detect correct options for netcat.
*src/rpc/virnetclient.c:
*src/rpc/virnetclient.h: Add function to handle connection to a libvirt
daemon using the libssh2 transport.
