* `fixfiles -B relabel` or `fixfiles -C previouscontext relabel` would
skip the code that handles e.g. `/var/tmp`, which would be run by
`fixfiles relabel`. It would still remove all files in /tmp (subject to
user confirmation). This is confusing, undocumented, and unlikely to
be intentional.
* `fixfiles relabel path1 path2` is the same, except it would only relabel
the first path.
* `fixfiles -R ... relabel` was equivalent to `fixfiles -R ... restore`,
again contradicting the man page.
Also `fixfiles onboot` would ignore paths, -C, or -R.
fixfiles is mostly for users, where it should be acceptable to remove these
non-sensical combinations.
`fixfiles -C` is used in selinux-policy rpm install scripts. However I
believe the rpms used `fixfiles -C previouscontext restore`, and did not
either require user interaction or blow away /tmp without prompting. So
they should still work fine.
With these combinations removed, we can remove the `exit` calls which were
seen in some of the (non-error) code paths in `restore()`.

`fixfiles -R -a` is much less useful than it was made to sound, because -R
now works recursively. Therefore `fixfiles -R -a` relabels every file on
the system, multiple times. On my system it took over 5 times as long as
plain `fixfiles` (which takes about a minute).

This commit allows the use of `set -u` to detect reads of unset variables.
But what I really liked was making the code more explicit about these
modes. I hope that this is easier for a new reader to reason about.
`fixfiles restore` has accumulated five different modes it can run in.
Now use a single variable to indicate the mode, out-of-band of the
variables used for the individual modes.
Apparently `set -u` / `set -o nounset` doesn't work correctly with arrays.
If we ever need bash arrays, we can simply remove `set -u`. The `set -u`
dialect is a strict subset. See http://mywiki.wooledge.org/BashFAQ/112
Extra notes:
RESTORE_MODE was created because I couldn't bring myself to use an empty
FILEPATH, as a special case to indicate the default mode. Arguments
to the script (paths) could be empty already, so it would mean I had to
work out how we behaved in that case and decide whether it was reasonable.
It turns out the `-B | -N time` mode is distinct and does not respect
paths. So we can tell the user we're not going to do anything with the
paths they passed. Make sure this distinction is shown in the usage error
message.
We already rejected the combination of `-R rpmpackage,... dir/file...`.
Being aware of the different modes just causes more bogus combinations
to be rejected.

Make sure usage() in fixfiles shows all the current options.
It's printed when there's a user error, so it needs to be
helpful! (Excluding the deprecated option - see below).
manpage:
Remove the deprecated option `-l logfile`.
Add missing space in `restore|[-f] relabel`.
It's not clear why `-R rpmpackagename` was considered optional in the
second invocation. (If the user omits it, they are just performing the
first invocation). It desn't match usage() in fixfiles either.
Clean up bolding for `fixfiles onboot`.
Disable justification (troff "adjustment") in the synopsis. We want the
common options in the different invocations to line up consistently.

Fix missing and surplus commas. Fix the following formatting errors:
.BR selinux(8)
renders the the "(8)" in bold as well as the "selinux". This is wrong.
.B selinux
(8)
renders with a space between "selinux" and "(8)", this is wrong.
.B selinux (8)
commits both of the above mistakes.
.BR selinux (8), apparmor (8)
omits the space separating "selinux(8)," and "apparmor(8)", this is wrong.
Correct all the above using the following markup:
.BR selinux (8),
.BR apparmor (8)

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.

Introduce a new file /etc/selinux/fixfiles_exclude_dirs which contains a
list of directories which should not be relabeled.
