Cygwin/X: Move duplicate extern variable declarations from various .c files to a new header file

Browse Source 
For the global variables defined in winglobals.c, remove duplicate extern
declarations from the beginning of various .c files, and move most of them
into a new header file, winglobals.h

Leave some clipboard related variables alone for the moment, they need treating
more carefully, to avoid mixing client and server type definitions.
