Man pages still showing version 1.0 in the 1.1 release

The patch coverts the man subdir to the standard xorg man page makefile.
The version number is automatically updated when a new release is made.
The man page section number is no longer hard coded either.

The package util-macros at version 1.8 or greater is required.

+statistics into cairo-trace-gvim.log file, and collecting 100 samples per

+Some GPUs report some units as busy when they aren't, such that even when
+idle and not hung, it will show up as 100% busy.
