New XMir in wily

With xorg-server 1.17.1-0ubuntu4 we have a new XMir codebase. This is
the code that was used for the MWC convergence demo [1].

There is now a special XMir XServer (/usr/bin/Xmir) in the "xmir"
package. The xserver-xorg-xmir package which had a plugin for
/usr/bin/X is now an empty transitional package. "/usr/bin/X -mir" no
longer works.

The old XMir code is now no longer supported. At some point there will
be a mass-closing of bugs - if you can reproduce an issue in the new
XMir please re-open.

Do to how cursors are now implemented you will currently not see
cursors when running inside unity-system-compositor. This will be
fixed [2].

Unfortunately since the new XMir requires cutting edge Mir features we
can't SRU this change to older releases. So if you want to play with
XMir please run wily.
