Revert mount/umount uevent removal

This change reverts the 033b96fd30db52a710d97b06f87d16fc59fee0f1 commit
from Kay Sievers that removed the mount/umount uevents from the kernel.
Some older versions of HAL still depend on these events to detect when a
new device has been mounted.  These events are not correctly emitted,
and are broken by design, and so, should not be relied upon by any
future program.  Instead, the /proc/mounts file should be polled to
properly detect this kind of event.

A feature-removal-schedule.txt entry has been added, noting when this
interface will be removed from the kernel.

+What:   mount/umount uevents
+When:   February 2007
+Why:    These events are not correct, and do not properly let userspace know
+        when a file system has been mounted or unmounted.  Userspace should
+        poll the /proc/mounts file instead to detect this properly.
