tests: also use lsmod to check whether modules are available (#10634)
It's not entirely impossible to screw something up playing with
kernel modules on a Saturday evening :-) This PR fixes a scenario
where a module has been loaded into the kernel but the module itself
has been removed from the disk.
A simple copy+paste mistake, since the reference to
systemd-localed.service was added to both locale.conf(5) and
vconsole.conf(5) in the same commit (8968e36f21).

test-network: wait after removing links
After ec6a47044a2ab321ae6427ce0d9fa3f6a17544a8, networkd starts
soon after removing links used by previous test. That causes
some racy situation of removing links and detecting links by networkd.
tests: make NetworkdNetWorkTests.test_routing_policy_rule pass on CentOS
Depending on the content of /etc/iproute2/rt_dsfield, ip can print either
`0x08` or `throughput` as was shown in https://github.com/systemd/systemd/issues/10617#issuecomment-435200859.

ask-password: check keyring in ask_password_tty and ask_password_agent
A race condition happens when calling ask_password_auto() multiple times
to unlock several disks on boot and effectively no password caching is
utilized. This patch fixes it by polling the cache when waiting for
the password.

network: also monitor udev 'change' event for network interfaces
If networkd starts earlier than all network interfaces are initialized,
then uninitialized interfaces are staying in pending state and cannot
become up.
With this, such interfaces are started after receiving 'change' event.

core: don't drop timer expired but not yet processed when system date is changed
There is difference between time set by the user and real elapsed time because of accuracy feature.
If you change the system date(or time) between these times, the timer drops.
You can easily reproduce it with the following command.
-----------------------------------------------------------
$ systemd-run --on-active=3s ls; sleep 3; date -s "`date`"

In the following command, the problem is rarely reproduced. But it exists.

man: don't claim that AssertXYZ= expressions failing had an effect on unit state
In the documentation for ConditionXYZ= we claimed that AssertXYZ= would
have an effect on unit state (which is wrong), while at the
documentation for AssertXYZ= we said it only has an effect on the job,
but not the unit (which is right). Let's fix this contradiction, and
only claim the latter.
Also, fix a couple of other things (for example, stop talking about a
"failure state", but let's just expressly called it "the 'failed' state",
as that's the actual name of that state.
Finally, let's emphasize again when the conditions/assertions are
executed, and that they hence are not useful to conditionalize deps.

core: skip unit deserialization and move to the next one when unit_deserialize() fails
If unit_deserialize() fails (because one read line is overly long), it returns
an error and we would have assumed that the next read would point to the next
unit to deserialize.
But instead unit_deserialize() can leave the file offset in the middle of a
line.
Therefore we need to ignore and skip the current unit in this case too.
While at it, move unit deserialization in a dedicated functions. That should
make the code easier to read.
journal: adapt for new improved LZ4_decompress_safe_partial()
With lz4 1.8.3, this function can now decompress partial results into a smaller
buffer. The release news don't say anything interesting, but the test case that
was previously failing now works OK.
Fixes #10259.
A test is added. It shows that with *older* lz4, a partial decompression can
occur with the returned size smaller then the requested number of bytes _and_
smaller then the size of the compressed data:
If we got such a short "successful" decompression in decompress_startswith() as
implemented before this patch, we could be confused and return a false negative
result. But it turns out that this only occurs with small output buffer
sizes. We use greedy_realloc() to manager the buffer, so it is always at least
64 bytes. I couldn't hit a case where decompress_startswith() would actually
return a bogus result. But since the lack of proof is not conclusive, the code
for *older* lz4 is changed too, just to be safe. We cannot rule out that on a
different architecture or with some unlucky compressed string we could hit this
corner case.
The fallback code is guarded by a version check. The check uses a function not
the compile-time define, because there was no soversion bump in lz4 or new
symbols, and we could be compiled against a newer lz4 and linked at runtime
with an older one. (This happens routinely e.g. when somebody upgrades a subset
of distro packages.)

hwdb: Apply the same quirk to all the lis3lv02d devices
HP laptops and desktop containing the lis3lv02d device (as supported by
the drivers/platform/x86/hp_accel.c driver) are supposed to output their
values according to their "standard" orientation, one that
corresponds to "can play neverball".
For all those devices, we need to convert that "neverball" orientation
to a "Windows 8" orientation. We will not accept quirks for HP machines
that use the lis3lv02d device, they should go in the hp_accel.c driver
instead.
test-compress: add test for short decompress_startswith calls
I thought this might fail with lz4 < 1.8.3, but it seems that because of
greedy_realloc, we always use a buffer that is large enough, and it always
passes.

cryptsetup-generator: allow whitespace characters in keydev specification
For example, <luks.uuid>=/keyfile:LABEL="KEYFILE FS" previously wouldn't
work, because we truncated label at the first whitespace character,
i.e. LABEL="KEYFILE".
lz4-r130 was released on May 29th, 2015. Let's drop the work-around for older
versions. In particular, we won't test any new code against those ancient
releases, so we shouldn't pretend they are supported.
I went through my antique collection of fuzzers the other day
to see which ones I hadn't sent upstream yet. This one
seems to be nice to have and ready to be merged. As far as I can
tell, it hasn't managed to find anything useful yet,
but it's better to be safe than sorry especially when it comes to networking
code :-)
