Steve Lawrence e501d3b6e8 libsepol/cil: better error message with duplicate aliases + support aliases to aliases
- If two typealiasactual statements exist for the same typealias, we get
  a confusing error message mentioning that the actual arguement is not
  an alias, which is clearly allowed. This poor error occurs because the
  first typealiasactual statement resolves correctly, but when we
  resolve the alias in the second typealiasactual statement,
  cil_resolve_name tries to return what the alias points to, which is a
  type and not the required typealias. This patch creates a new function
  that does not perform the alias to actual conversion, used when we
  want an alias and not what the alias points to. This allows the
  cil_resolve_aliasactual to continue and reach the check for duplicate
  typealiasactual statements, resulting in a more meaningful error
  message.

- Add back support for aliases to aliases (broken in 5c9fcb02e),
  while still ensuring that aliases point to either the correct actual
  flavor or alias flavor, and not something else like a typeattribute.

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).
