In order to support filenames, which might start with "." or filesystems
that start with a number we need to rework the matching rules a little
bit. Since the new filename rule is so permissive it must be moved to
the bottom of the matching list to not cover other definitions.

expand_role_attributes() would merge the sub role attribute's roles
ebitmap into that of the parent, then clear it off from the parent's
roles ebitmap. This supports the assertion in role_fix_callback() that
any role attribute's roles ebitmap contains just regular roles.
expand_role_attribute() works on base.p_roles table but not any
block/decl's p_roles table, so the above assertion in role_fix_callback
could fail when it is called for block/decl and some role attribute is
added into another.
Since the effect of get_local_role() would have been complemented by
the populate_roleattributes() at the end of the link phase, there is
no needs(and wrong) to call role_fix_callback() for block/decl in the
expand phase.

Allow the specification of python3 in the swig creation
This patch adds the new option PYPREFIX which causes the swig created
libraries to have a prefix. This allows one to build both the python2
and python3 libraries in the same source tree. The install will then
later strip this prefix back off when it drops the files into the python
approriate site package directory.
This patch also needs to update the PYINC definition as newer python
patckages on fedora exist in /usr/include/python3.2mu instead of
/usr/include/python3.2 as the other method of detemrining PYINC would
have found.

The Fedora Distribution is looking to standardize kernel subsystem file
systems to be mounted under /sys/fs. They would like us to move /selinux
to /sys/fs/selinux. This patch changes libselinux in the following
ways:
1. load_policy will first check if /sys/fs/selinux exists and mount the
selinuxfs at this location, if it does not exists it will fall back to
mounting the file system at /selinux (if it exists).
2. The init functions of selinux will now check if /sys/fs/selinux is
mounted, if it is and has an SELinuxfs mounted on it, the code will then
check if the selinuxfs is mounted rw, if it is, libselinux will set the
mountpoint, if it is readonly, libselinux will return no mountpoint. If
/sys/fs/selinux does not exists, the same check will be done for
/selinux and finally for an entry in /proc/mounts.
NOTE: We added the check for RO, to allow tools like mock to be able to
tell a chroot that SELinux is disabled while enforcing it outside the
chroot.
$ getenforce
Enabled
$ mount --bind /selinux /var/chroot/selinux
$ mount -o remount,ro /var/chroot/selinux
$ chroot /var/chroot
$ getenforce
Disabled
3. In order to make this work, I needed to stop enabled from checking if
/proc/filesystem for entries if selinux_mnt did not exist. Now enabeled
checks if selinux_mnt has been discovered otherwise it will report
selinux disabled.
