Support mounts by unprivileged users

Registered by Serge Hallyn

Much work has been done to safely support mounting (especially bind
mounts) by unprivileged users. The last attempt (in 2008) to push this
functionality stopped the problem of possible DOS on rmdir/unlink
by unprivileged users, as documented at

 http://lkml.org/lkml/2008/9/11/162

Working with the community on a workaround and finally pushing this
functionality could allow a pretty great reduction in the amount
of root access needed to do useful mounting.
