The fuzzer is supposed to cover `mnt_table_parse_stream`, which is
used by systemd to parse /proc/self/mountinfo. The systemd project
has run into memory leaks there at least twice:
https://github.com/systemd/systemd/pull/12252#issuecomment-482804040https://github.com/systemd/systemd/issues/8504
so it seems to be a good idea to continuously fuzz that particular
function.
The patch can be tested locally by installing clang and running
./tools/oss-fuzz.sh. Currently the fuzzer is failing with
```

Once the bug is fixed and the OSS-Fuzz counterpart is merged it should be possible
to turn on CIFuzz to make sure the fuzz target can be built and run for some time
without crashing: https://google.github.io/oss-fuzz/getting-started/continuous-integration/

Sorry detail-oriented people tend to wipe these out if they notice them.
Add in automated tools and lots of excess end-of-line spaces get wiped
out.

use
$ make CU_DUMP=1 checkusage
for easily reviewing and comparing all output in
/tmp/checkusage--help
/tmp/checkusage--version
/tmp/checkusage--unknownopt
This was a big help when doing all my last usage cleanup.
Actually I used it to dump the original output, edited it
how I would like it, and then changed our programs to match
the wanted output.

Sorry, don't know why I reverted fad561b0.
But for travis we need it only in check_nonroot().
check_root() *can* do chown and the check_dist() is handled
by Makefile.

Just some simple generic tests for our UL commands, regarding
options --help, --version and --unknownopt.
The script looks still a bit weired but could be polished to
be used in tests/. It would be the first time testing at least
"something" for *all* built binaries (currently 109! commands).
For the record here are the current candidates with possible
problems:
$ make checkusage
agetty: --unknownopt, stderr too long: 45
blockdev: --unknownopt, stderr too long: 28
flock: --help, no stdout
flock: --help, non-empty stderr
getopt: --help, returns error
kill: --unknownopt, stderr too short: 1
lsipc: --unknownopt, stderr too long: 77
pg: --unknownopt, stderr too long: 23
renice: --unknownopt, stderr too long: 18
rtcwake: --unknownopt, non-empty stdout

* add UL_ENABLE_ALIAS(NAME, MASTERNAME) to initialize $enable_<name>
according to MASTERNAME. Note that we have to use $build_<mastername>,
the $enable_<mastername> is just AC_ARG_ENABLE() stuff only. The
$build_ is evaluated and modified by our UL_...() functions.
* add enable-schedutils.conf to have build-system regression test for
this use-case

We have "make" targets which depends on tools/check*.sh scripts. It's
ugly to exclude these scripts from the release tar balls (as generated
by "make distcheck").
