Currently the semanage.conf file is hard coded to /etc/selinux/semanage.conf
even when an alternate root path is specified. Use the semanage.conf
found inside the altername root instead of the system global version.

Fix the handling of namespaces in seunshare/sandbox.
Currently mounting of directories within sandbox is propogating to the
parent namesspace. This fix will basically isolate any mounting that
happens after the unshare from the parent namespace.

We would like to be able to say that the user, role, or range of a newly
created object should be based on the user, role, or range of either the
source or the target of the creation operation. aka, for a new file
this could be the user of the creating process or the user or the parent
directory. This patch implements the new language and the policydb
support to give this information to the kernel.

When selabel_lookup found an invalid context with validation enabled, it
always stated it was 'file_contexts' whether media, x, db or file.
The fix is to store the spec file name in the selabel_lookup_rec on
selabel_open and use this as output for logs. Also a minor fix if key is
NULL to stop seg faults.

For a long time /root has been treated differently in Red Hat
Distributions then upstream policy.
We do not want to label /root the same as a users homedir. Because of
this we have carried a patch in libsemanage/genhomedircon.c to ignore
/root.
This patch adds a flag to semanage.conf, ignoredirs. That will allow
distributions or users to specify directories that genhomedircon
should ignore when setting up users homedir labeling.
