test-hashmap: add test to compare hashmap_free performance

custom_free_hash_ops test took 2.589327s
string_hash_ops test took 2.319137s
custom_free_hash_ops test took 2.584038s
code with a patch which restores the "fast path" using:
for (idx = skip_free_buckets(h, 0); idx != IDX_NIL; idx = skip_free_buckets(h, idx + 1))
in the case where both free_key and free_value are either free or NULL:
/* test_hashmap_free (slow, 1048576 entries) */
string_hash_ops test took 2.347013s
custom_free_hash_ops test took 2.585104s

custom_free_hash_ops test took 2.621675s
string_hash_ops test took 2.334675s
custom_free_hash_ops test took 2.601568s
So the test is noisy, but there clearly is no significant difference with the
"fast path" restored. I'm surprised by this, but it shows that the current
"safe" implementation does not cause a performance loss.
When the code is compiled with optimization, those times are significantly
lower (e.g. 1.1s and 1.4s), but again, there is no difference with the "fast

dissect-image: wait for the main device and all partitions to be known by udev
Fixes #10526.
Even if we waited for the root device to appear, the mount could still fail if
we didn't wait for udev to initalize the device. In particular, the
/dev/block/n:m path used to mount the device is created by udev, and nspawn
would sometimes win the race and the mount would fail with -ENOENT.
The same wait is done for partitions, since if we try to mount them, the same
considerations apply.
Note: I first implemented a version which just does a loop (with a short wait).
In that approach, udev takes on average ~800 µs to initialize the loopback
device. The approach where we set up a monitor and avoid the loop is a bit
nicer. There doesn't seem to be a significant difference in speed.
With 1000 invocations of 'systemd-nspawn -i image.squashfs echo':
loop (previous approach):
real 4m52.625s
user 0m37.094s

dissect-image: wait for the root to appear
dissect-image would wait for the root device and paritions to appear. But if we
had an image with no partitions, we'd not wait at all. If the kernel or udev
were slow in creating device nodes or symlinks, subsequent mount attempt might
fail if nspawn won the race.
Calling wait_for_partitions_to_appear() in case of no partitions means that we
verify that the kernel agrees that there are no partitions. We verify that the
kernel sees the same number of partitions as blkid, so let's that also in this
case.
This makes the failure in #10526 much less likely, but doesn't eliminate it
completely. Stay tuned.

- In v1, the old object was always used and the device received back from the

equivalent in both cases, because by the time we the callback gets called,
the db entry in the filesystem will also exist, and any subsequent access to

simple. This code is written very defensively so that incompatibilities
don't affect us much.
Given that glibc really has a duty to maintain compat between
differently compiled programs and their system nscd they can't break API
and thus it should be safe for us to implement an alternative,
minimalistic client.
Ideally this kind of explicit, global cache flushing would not be necessary.
However nscd currently has no cache coherency protocol, hence we can't
really implement this better. The only concept it knows is a TTL for
positive hosts lookups. Hoewver for negative lookups or any of the other
tables nothing is available.

lldp: simplify compare_func, using ?: to chain comparisons
The ?: operator is very useful for chaining comparison functions
(strcmp, memcmp, CMP), since its behavior is to return the result
of the comparison function call if non-zero, or continue evaluating
the chain of comparison functions.
This simplifies the code in that using a temporary `r` variable
to store the function results is no longer necessary and the checks
for non-zero to return are no longer needed either, resulting in a
typical three-fold reduction to the number of lines in the code.
Introduce a new memcmp_nn() to compare two memory buffers in
lexicographic order, taking length in consideration.
Tested: $ ninja -C build/ test
All test cases pass. In particular, test_multiple_neighbors_sorted()
in test-lldp would catch regressions introduced by this commit.

Note that this issue only affected in4_addr_netmask_to_prefixlen()

It may seem slightly odd, to return 32 (bits) for utz(0). But that
is what in4_addr_netmask_to_prefixlen() needs, and it probably makes

We already *install* those as real files since

Meson will start to copy symlinks as-is, so we would get dangling symlinks in
/usr/lib/systemd/user/.
I considered the layout in our sources to match the layout in the installation
filesystem (i.e. creating units/system/ and moving all files from units/ to
units/system/), but that seems overkill. By using normal files for both we get
some duplication, but those files change rarely, so it's not a big downside in
practice.
