Implement output transformations.

Browse Source 
This patch allows rotation and mirroring outputs for x11 and drm backends.
A new 'transform' key can be set in the [output] section. From the protocol:

"The flipped values correspond to an initial flip around a vertical axis
followed by rotation."

The transform key can be one of the following 8 strings:

normal
90
180
270
flipped
flipped-90
flipped-180
flipped-270
