Keith Packard 2dc138922b Rename region macros to eliminate screen argument
This is a combination of a huge mechanical patch and a few small
fixups required to finish the job. They were reviewed separately, but
because the server does not build without both pieces, I've merged
them together at this time.

The mechanical changes were performed by running the included
'fix-region' script over the whole tree:

$ git ls-files | grep -v '^fix-' | xargs ./fix-region

And then, the white space errors in the resulting patch were fixed
using the provided fix-patch-whitespace script.

$ sh ./fix-patch-whitespace

Thanks to Jamey Sharp for the mighty fine sed-generating sed script.

The hand-done changes involve removing functions from dix/region.c
that duplicate inline functions in include/regionstr.h, along with
their declarations in regionstr.h, mi.h and mispans.h.
