The libtool based build system uses scripts rather than real binaries
in $top_builddir. It's necessary to use libtool --mode=execute to call
valgrind for the real binary (from .libs/).

lsmem currently calculates the total online/offline memory by iterating
over all lsmem->blocks. Depending on the lsmem options, there may be
only one lsmem->block, because all sysfs memory blocks could be merged
into one. In this case, the calculation is wrong, because the individual
online/offline state of the sysfs memory blocks is not preserved, but
rather lsmem->blocks[0].state is set to the state of the first sysfs
memory block, typically MEMORY_STATE_ONLINE (at least on s390).
This means that "Total offline memory" will always be calculated as 0
in such cases, e.g. when using "lsmem --summary", or any options that
would merge the table output to one line, like "lsmem -o RANGE":
~# lsmem --summary
Memory block size: 1G
Total online memory: 20G
Total offline memory: 0B
Adding the "-a" option shows the real summary, since there is no block
merging going on, and the calculation is therefore correct:
~# lsmem -a --summary
Memory block size: 1G
Total online memory: 16G
Total offline memory: 4G
Fix this by moving the online/offline calculation into the loop that
is iterating over all sysfs memory blocks, instead of iterating over
potentially merged lsmem->blocks.

The current code uses lose_counter to make more attempts to read
random numbers. It seems better to wait a moment between attempts to
avoid busy loop (we do the same in all-io.h).
The worst case is 1 second delay for all random_get_bytes() on systems
with uninitialized entropy pool -- for example you call sfdisk (MBR Id
or GPT UUIDs) on very first boot, etc. In this case it will use libc
rand() as a fallback solution.
Note that we do not use random numbers for security sensitive things
like keys or so. It's used for random based UUIDs etc.

Unfortunately, old version of the file linux/fs.h defines MS_*
macros, so the file cannot be included together with sys/mount.h.
We include sys/mount.h from libmount.h now.

Let's include sys/mount.h to be sure that our local libmount fallbacks
are not used by default to avoid possible conflicts with later included
sys/mount.h.

In Endless we have hit a problem when using 'sfdisk' on the really first
boot to automatically expand the rootfs partition. On this platform
'sfdisk' is blocking on getrandom() because not enough random bytes are
available. This is an ARM platform without a hwrng.
We fix this passing GRND_NONBLOCK to getrandom(). 'sfdisk' will use the
best entropy it has available and fallback only as necessary.

Regarding parallel root checks ...
- fix: add a few missing "udevadm settle" where we are using LABELs or UUIDs
- introduce ts_udevadm_settle():
* Still trivial implementation. The idea is to use it in future for all
tests instead of directly calling "udevadm settle". So we could add debug
messages, wait for specific events, add code for non-udev systems or even
use "udevadm --{start,stop}-exec-queue" to be really sure what we are
doing and why using udevadm at all.
* The currently unused args may be used in future and show the code reader
already now why we are calling "udevadm settle" at all.
* So far this patch only affects swapon/, mount/, libmount/ tests, and is
only about UUIDs and LABELs, but may be continued later for "partitions",
"md devices", whatever.
* We are calling ts_udevadm_settle() right *before* we need a LABEL or
UUID, not just *after* we created one. This may be a bit better for
speed and shows the code reader which command would fail without settle.
- function ts_device_has_uuid() is unused now, we trust blkid(1). Renamed to
ts_is_uuid() in case we would need it again.

ts_is_mounted "/dev/loop1" returned true if /dev/loop17 was
mounted. A very annoying source of sporadic failures since
many years. This issue became more visible since running the
checks in parallel, which increases the probability to get
bigger loop device numbers.

When cpu#0 is offline, atof(NULL) is called which causes
a segfault or endless loop depending on implementation
circumstances. So instead of implicitely assumping that the
first cpu is always available, do the presence checks for
all including the first one.

Bash 4 is now almost 10 years old and it seemed to be fine in 613a337e
to use associative arrays. Unfortunately OSX will probably never update
to 4 because of GPLv3. We don't want to lose our travis OSX build and
use plain arrays again.
BTW remove that "informative warnings" about unlocked resources. They
were only silent so far because of a bug. Any system where scsi_debug
is broken would print a lot of these warnings. This also tells us that
we could even stop calling ts_unlock() explicitly. Just exiting the
tests would be good enough.
Note that currently flock(1) is not available on our OSX build anyways.

The only situation where we would block endless is if another parallel test
has the lock and hangs for another reason. This means that the other test
would still keep hanging even if we timeout here. The user would have to
interrupt the other test or the whole test-suite anyways.
Note that we would certainly run into any timeout when using --parallel=200,
so that all scsi tests start the same time.

The test-suite did not survive when flock timeouts after 30s because
then ts_cleanup_on_exit() may use resources (e.g. rmmod scsi_debug)
while not having the lock.

On debian-kfreebsd we've locked stdout which messed up our test logs. Using
/proc/*/fd/ is not portable. Even ts_init's test for "/proc/self/fd"
does not help because /proc/*/fd behaves strange here:
$ ls -l /proc/$$/fd
lr--r--r-- 1 rudi user 0 Mar 6 23:11 /proc/2194/fd -> unknown
$ file /proc/$$/fd
/proc/2194/fd: broken symbolic link to `unknown'
## wtf?
$ test -d /proc/$$/fd; echo $?
0
$ ls -l /proc/$$/fd/
ls: cannot access /proc/2194/fd/: No such file or directory
## but
$ ls -l /proc/self/fd/

I still don't understand why this helps to fix these tests on my system.
udevadm settle had no positive effect. Adding the sleeps before
"is_mounted" also didn't fixed that, that's amazing!?

The example given in the man page didn't work. Judging by commit
db663995bd, --inh-caps= used to be called
--caps= but the man page was not updated after the change was made.
