xserver: delete pervasively use of DISPATCH_PROC
Some functions had to be moved around due some missing static definitions.
Another minor clean up like inexistent function declarations and etc were made
also.
Part of this patch was cooked using:
sed -i -e '/static DISPATCH_PROC*.*;/d' `git ls-files`
