Stephen Smalley d1769a9b83 libselinux: always unmount selinuxfs for SELINUX=disabled 
As reported in:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=864479
using a kernel configuration with CONFIG_SECURITY_SELINUX_DISABLE=n
and a /etc/selinux/config with SELINUX=disabled leads to a boot
failure.

Fix this by always unmounting selinuxfs if /etc/selinux/config has
SELINUX=disabled even if unable to successfully disable SELinux.
This will ensure that subsequent is_selinux_enabled() tests will
return 0 (disabled) and userspace will therefore skip any SELinux
processing.

Build dependencies on Fedora:
yum install audit-libs-devel bison bzip2-devel dbus-devel dbus-glib-devel flex flex-devel flex-static glib2-devel libcap-devel libcap-ng-devel pam-devel pcre-devel python-devel setools-devel swig xmlto redhat-rpm-config

To build and install everything under a private directory, run:
make DESTDIR=~/obj install install-pywrap

To install as the default system libraries and binaries
(overwriting any previously installed ones - dangerous!),
on x86_64, run:
make LIBDIR=/usr/lib64 SHLIBDIR=/lib64 install install-pywrap relabel
or on x86 (32-bit), run:
make install install-pywrap relabel

This may render your system unusable if the upstream SELinux userspace
lacks library functions or other dependencies relied upon by your
distribution.  If it breaks, you get to keep both pieces.

To install libsepol on macOS (mainly for policy analysis):
cd libsepol; make DESTDIR=/usr/local PREFIX=/usr/local install

This requires GNU coreutils (brew install coreutils).
