Multiple patches to policycoreutils.
First added /root/.ssh and /root/.ssh/* to allow people to place keys
in /root directory and have them labeled by restorcond
<snipdue to previously ack'd patch>
Clean up permissive domains creation in semanage so it does not leave
crap in /var/lib/selinux

Also have fixfiles operate recursively when in RPM mode, per:

If a package owned a directory like /var/lib/libvirt/images, when it is
relabeling we would want it to relabel not only the directory but the
contents of the directory

I think this patch fixes the transaction patch in semanage.

Change semanage/seobject to use semanage_mls_enabled() rather than
is_selinux_mls_enabled(). I dropped the mls enabled tests altogether
from the semanage front-end script since setting up a handle is done by
seobject.py; if those checks are actually important, we could move them
inside of the seobject methods, but I'm not clear on the real benefit of
those checks. In seobject.py, I moved the setting of the is_mls_enabled
variable inside of get_handle(store) after the connect. I also dropped
the is_mls_enabled test from setransRecords since no handle/connection
exists there (since translations are not managed via libsemanage), and
again I'm not clear that the check there was overly important/useful.

Currently semanage is not allowed to change a file context mapping if it
matches exactly, this patch allows you to modify the file context.

Change semange fcontext -a to check for local customizations rather then
global, so you can modify a file context.

Sorry, it took some time. The revised patch for nodecon support in
the semanage tool is attached.
It now takes strings as arguments for the ip protocol. list/locallist
work as expected and output is more readable. I also made changes for
the semanage.8 man page.

Christian
