There is currently no way to determine the libvirt version of a remote
libvirtd we are connected to. This is a useful piece of data to enable
feature detection.
Since virMigratePrepareTunnel() is used for migration over the
native libvirt connection, there is never any need to pass the
target URI to this method.

src/remote/remote_protocol.x: Remove 'uri_in' parameter from
virMigratePrepareTunnel() method
The code which updated the message length after writing the
payload wrote the updated length word in the wrong place since
the XDR object was given a buffer pointing to the start of the
header payload, rather than message start.
* daemon/remote.c: Fix updating of event message length so that
we actually send the payload, not just the header
Implementation of tunnelled migration, using a Unix Domain Socket
on the qemu backend. Note that this requires very new versions of
qemu (0.10.7 at least) in order to get the appropriate bugfixes.

Add the virStrncpy function, which takes a dst string, source string,
the number of bytes to copy and the number of bytes available in the
dest string. If the source string is too large to fit into the
destination string, including the \0 byte, then no data is copied and
the function returns NULL. Otherwise, this function copies n bytes
from source into dst, including the \0, and returns a pointer to the
dst string. This function is intended to replace all unsafe uses
of strncpy in the code base, since strncpy does *not* guarantee that
the buffer terminates with a \0.
