xserver 1.14 ready for testing in saucy

[Maarten Lankhorst]

With the upload of a newer fglrx all bits are in place for a smooth transition to x1.14.
Considering there are no version changes for mesa or any of the ddx drivers I don't expect
any driver specific regression with the open source drivers.

For now it requires the unity ppa, and the unity from the x-staging ppa:

sudo add-apt-repository ppa:ubuntu-unity/daily-build
sudo add-apt-repository ppa:canonical-x/x-staging
sudo apt-get update
sudo apt-get dist-upgrade

All test results welcome, but unity specific bugs that don't disappear with x-staging
purged with should be filed against unity.

The binary drivers for the pandaboard don't work with the new abi and there
will not be a new driver for them. If you really want to upgrade install
xserver-xorg-core-omap-revert from the ppa. It is only provided to have
a xserver for pandaboards that's compatible with the new pointer barriers,
and it will very likely not receive any further updates.
