This allows us to specify under which the compiled policy file and context configuration
files exist. We can use this with matchpathcon to check the labels under alternate policies,
and we can use it for sepolicy manpage to build manpages during policy build.
We may want to force matchpathcon to respond if the path is question is
a dir, sockfile, chr, blk, etc. Add an option so you can force it to
hit the right rule types.

We declare rc both for a function and inside a stanze. We only need it in the
stanze so remove the declaration for the whole function.

selinux_file_context_verify(3) should now return the correct codes and
matchpathcon(8) has been modified to handle them.
The selinux_file_context_verify(3)and selinux_file_context_cmp(3) man pages
have also been updated (re-written really) to correct return codes.
I found that selabel_open left errno set to ENOENT because a
file_contexts.subs file did not exist on my system, but left selabel_open
alone and set errno = 0 before calling selinux_filecontext_cmp.

Instead of only doing path simplification and symlink following for the
matchpathcon helper instead do it in the library potion. This was an
issue when in python some called selinux.matchpatchcon("//lib64", 0) and
got the wrong answer (because the // wasn't being dealt with)

matchpathcon cannot handle ./ or ../ in pathnames and doesn't do well
with symlinks. This patch uses the glibc function realpath() to try to
determine a real path with resolved symlinks and dot directories. For
example before this pach we would see:
$ matchpathcon /tmp/../eric
/tmp/../eric <<none>>
$ matchpathcon /eric
/eric system_u:object_r:default_t:s0
Whereas after the path we get the same results. The one quirk with the
patch is that we need special code to make sure that realpath() does not
follow a symlink if it is the final component. aka if we have a symlink
from /eric to /tmp/eric we do not want to resolv to /tmp/eric. We want
to just resolv to the actual symlink /eric.

matchpathcon -V should be passing the mode when checking whether the
file context on a file is correct.
