Avoid polling in global-auto-revert-mode (bug#35418)
Make `auto-revert-avoid-polling' have effect in global-auto-revert-mode.
Buffers actually handled by that mode are marked with a non-nil value
of `auto-revert--global-mode'. When global-auto-revert-mode is

to mark new buffers and take care of buffers whose file names change.
This way the existing poll-avoidance logic can be used, since the
