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.

Now it chunks one list by it's filename_trans->stype value to limit length of

This patch started with work from John Reiser patch to estimate the
percent progress for restorecon/setfiles.
It has a lot of changes since then, to make it only happen on full
relabel, overwrite itself, shows 10ths of %, and does a lot better and
more useful job of estimation. We get all of the inodes on all mounted
FS. Since the number of inodes is not fixed and only an estimate I added
5% to the inode number, and forced the number to never go over 100.

It dynamically creates the policycoreutils "genhomedircon"
script during the build process in order not to hard-code
the full path to the semodule executable, as in general the
latter could reside in non-standard SBINDIR/USRSBINDIR
locations.
It might not be very stylish or it might appear cumbersome,
but at least the script should not break as easily as the
current static one.
The patch also edits the Makefile for the scripts so that
LOCALEDIR correctly uses $(PREFIX) rather than an absolute
path.

- clarify the above mentioned manual page(s), in particular relatively
