more-output-conflict-avoidance-761.patch

Rebase my patch against the latest release.

Apparently I'm still the only person with more than one non-SLI radeon card in
his or her system using xrandr --setprovideroutputsource.

Then again, maybe that's because all the non-hackers that try give up when
their /usr/bin/X segfaults, concluding that the feature does not work for
dual-radeon configurations (they are more-or-less right).

However, note that these folks still have duplicate output names, which must
cause all sorts of havoc on their systems.  Without the segfault, perhaps they
can barely limp along, so long as they don't do anything too interesting with
xrandr.  Oh, well, tough cookies for them, I guess, since due to the
non-obvious etiology of their problems, their chances of finding this bug and
applying my patch are poor.

As with the previous revision, this one should still preserve the legacy output
names perfectly.
