The semodule_path file, inside scripts, which is used to tell the
Makefile where genhomedircon should point to find semodule, was not
being updated. This patch makes sure we update this file every time
something builds, thus genhomedircon doesn't point to some wild out of
data file location.

This patch adds support for displaying SELinux context information in
colors defined by mcstrans(8)/secolor.conf(5). The new behavior is
enabled through the use of the "-C/--color" option and requires the
"-P" option also be specified.
The reason for this addition is that in some situations, notably MLS,
users find it helpful to add SELinux context information to their prompt:
# example taken from the RHEL6 CC certification bash scripts
SEROLE=`secon -rP 2>/dev/null`
SEMLS=`secon -lP 2>/dev/null`
PS1="[\u/$SEROLE/$SEMLS@\h \W]\\$ "
export PS1
With the added functionality provided by this patch we can also display
the associated color information (note the addition of the "C" option):
SEROLE=`secon -rP 2>/dev/null`
SEMLS=`secon -lPC 2>/dev/null`
PS1="[\u/$SEROLE/$SEMLS@\h \W]\\$ "
export PS1
Note that in the example above only the MLS range is colored, but the
patch does provide support for all of the color information provided
by mcstransd/secolor.conf (user,role,type,range).
Finally, one quick word on the colors themselves; the secolor.conf
configuration file allows 32-bit colors but the ANSI color coding only
allows 8-bit colors so the colors displayed by secon using the "-C"
option will be a bit lossy.

We currently have a mechanism in which the default user, role, and range
can be picked up from the source or the target object. This implements
the same thing for types. The kernel will override this with type
transition rules and similar. This is just the default if nothing
specific is given.

EOPNOTSUPP means "operation not supoorted on socket", and ENOTSUP means
"not supported", although per POSIX they can be alised to the same
value and on Linux they do, ENOTSUP seems the more correct error code.
In addition these function are documented as returning ENOTSUP, and
given that they are implemented in means of getxattr(2) which does
return ENOTSUP too, this just consolidates their behaviour.

- Add man page sections '(N)' to external references, and '()' on
functions described in the same man page.
- Escape minus signs when those are expected to be used on the command
line or files.
- Mark files and variables in italic; Note headings, function names,
constants, program options and man page references in bold.
- Do not justify and hyphenate SEE ALSO section, and avoid hyphenation
on symbol names by prepending them with \%.
- Remove trailing dot from NAME section description.
- Split sections with a no-op command '.', to visually distinguish them
but to avoid introducing spurious vertical space in the formatted
output.
- Add explicit .sp commands in the SYNOPSIS section between function
prototypes, and fix space placement in function protoypes.
- Split header includes with .br (instead of the explicit or implicit
.sp) so that they are vertically contiguous.
- Add missing {} around SELINUXTYPE and POLICYTYPE variable text in
paths.
- Remove unneeded formatting commands.
- Remove spurious blank lines.

If you specified a portion of the module name the code would disable the module rather
then giving you an error. For example.
semodule -d http
Would disable the httpd module.
As a matter of fact
semodule -r h
Would disable the first module file name that began with h.
This patch gets the real file name out of the modules and compares it to the name specified.
It also consolodates a bunch of duplicated code, and fixes a return code bug.

update-po is a mechanism for sucking the latest english translations
out of the source code, but it ALWAYS updates all of the po files with things
like the last time the update-po was run even if there are no changes. This
results in having to do git checkins any time you run make at the top level.
Since so few people interact with the Translators I believe this should
be done on demand when they think it is time to get new translations.
