b98e5657ee testsuite: ps out tests more lenient
Sometimes due to race conditions or the way dejagnu gates the
output, or even there is another interesting process, the ps tests
sometimes fail. These changes make it a little more lenient without
losing the purpose of the test.

Replaces Debian patch ps_tests

d557ad8a6e testsuite: Return error if tty is TTY
In some build systems, such as the Debian pbuilders, the
environment is strange. The tty is called "TTY" which causes
some of the ps tests to fail.

This commit checks for that specific result and returns ""
so the tests can be bypassed.

Replaces Debian patch fix_checks.

6389deca5b sysctl: Support systemd glob patterns
systemd-sysctl handles glob patterns along with overrides and
exceptions. Now the procps sysctl does it too.

The return value for sysctl is consistently either 0 or 1.

Added tests to check sysctl functions.

fc97889b2d build-sys: Handle zero length diskstats in tests
vmstat -d testsuite will fail if your /proc/diskstats is present
but zero length. While this seems buggy behaviour from lxcfs, its
there and its a simple matter to test for it and skip those tests
if we are run on a zero length /proc/diskstats system.

2e1e8fcc85 slabtop: Check for bad d and o option combination
If you run slabtop with the -d option and then -o option the
delay gets set to zero and it runs forever. slabtop now checks
for this combination and errors.

Adding a DEJAGNU test also found that none of the slabtop
checks were running so they got added to the list and only the
ones that need /proc/slabinfo (if not readable) are skipped.

557fda8f98 build-sys: Enable testing of sigqueue
The referenced commits enavled both pkill and kill to send an integer to
the killed or signalled process. The test_process now will report on the
integer if sent and the testsuite changes take advantage of this
new feature.

Another process make/destroy set had to be made as using spawn
instead of exec changes both the SID and TTY for the underlying
process, making other tests fail.

aa41c309dd kill: -l space between name parses correctly
This was supposed to be just a cherry-pick of the referenced
commit. However there were two problems:
 1. kill code was moved out to its own file
 2. strtosig() had a latent bug where signal numbers were not
 converted to names.

Original note:
kill -lHUP would work correctly, but kill -l HUP would not.

The list option in kill was hit by a quirk of getopt_long where an
option with an optional argument would not attempt to get the argument
beyond the space, even though a mandatory argument would do that.

The fix is a kludge to scan to the next argument and if it looks
like something we can use, use it. Lucky for us, the list option is
one where parsing can stop immediately.

Thanks to Brian Vandenberg for the way forward.

e40b0060c2 tests: slabinfo should not be too strict about slab names
Before this commit, the test checking `vmstat -m` (slabinfo) output uses
a fairly strict regular expression that only allows alphanumeric
characters and a few exceptions such as "_", "-", "(" and ")".

However, recent kernels use a wider range of characters, such as ">".
For instance, see this Linux commit which creates a "page->ptl" slab:
  https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/mm/memory.c?id=b35f1819acd9243a3ff7ad25b1fa8bd6bfe80fb2#n4283

Other patches for reporting slab usage per memcg include the names of
the cgroup in the slabinfo output, which can include additional
characters and use dots for abbreviation.

The check should not be so string, instead it could simply look for a
chain of non-whitespace characters and that should be enough.

Tested that `make check` is still working, including in some of the
environments where features that enable the additional slabinfo names.

af6e264b46 tests: fix regexp in ps_sched_batch.exp to match in first line
The current regexp checks for a \s+ in the beginning, however that will
only match if there is a \n in the `ps` output before test-schedbatch,
but that will not happen if test-schedbatch is the first process in the
list, which happens if the PID of test-schedbatch is low enough to bring
it up in the sorted list.

Fix it by enabling newline-sensitive matching with (?n) which then
allows using ^ and $ anchors in the regexp (including an optional \r
introduced by expect.) Matching the end of line also improves checking
that the last field matches 18 exactly and not something like 181, etc.

Tested that `make check` does not break and also fixed the flakiness
seen in an environment with few processes running under the test user
which made the issue more frequent.

e981f2bbd2 tests: do not mark ps_sched_batch.exp as untested
Right now the test case is both testing it (expect_pass "$test") and
marking it as untested (untested "$test"), it should do either one or
the other, so stop marking it as untested.

Before this change, these lines appear in testsuite/ps.log or the output
of `make check RUNTESTFLAGS="--all"`:

  PASS: ps SCHED_BATCH scheduler
  UNTESTED: ps SCHED_BATCH scheduler

Note that the second line is confusing, it's implying that the test is
untested, right after having tested it and indicated it passes.

After this change, only the first line will appear.

Tested that both `make check` and `make distcheck` continue working with
this commit.

f8e98b65ae free: Use IEC units
Free always used 1024 based units but used the confusing old style
kilo,mega etc.

This change changes the names to kibi,mebi for 1024 based divisors
and kilo,mega for 1000 based divisors or IEC units.

It also checks if you try to set two units, e.g free -k -m
Petabyte and Pebibyte have been added.

If you used to use the long options such as --mega these will now
actually print megabytes (they previously printed mebibytes).
The short options are being used on the IEC units

cacba5613e Reliably kill test processes
It seems command -v also includes built-ins so checking for kill
is useless because it finds the built-in and those machines or
environments that have no /bin/kill fail at the check stage.
Oh and then TCL exec doesn't spawn a shell.

After reading way too many TCL websites, I believe this should
fix the problem. TCL quoting is... different to say the least but
it works reliably here. The script now even picked up a typo elsewhere
which was nice.

This change should stop the intermittent FTBFS bugs from the Debian
pbuilders, I hope! You'd think kill $var wouldn't be this difficult.

5a34ff0a99 Check for presence of disks in vmstat
vmstat -d or vmstat -p would crash mysteriously under different
circumstances. The problem was eventually tracked down to /sys not
being mounted which meant is_disk() always returned false.
The partition would then be attempted to be linked to a non-existent
disk causing a segfault.

vmstat will now not link to a disk if none exists.
The change in testing will skip those tests when /sys/block doesn't
exist.

Many thanks to Daniel Schepler for his analysis and suggestions.
