This reverts commit 4f5e972279.
Building with gperf 3.0 works just fine; we had an autoconf check to
determine the correct data types, and this check was ported to meson.
All test/TEST* but TEST-02-CRYPTSETUP share the same check_result_qemu()
and test_cleanup(), so move them into test_functions and only override
them in TEST-02-CRYPTSETUP.
Also provide a common test_run() which by default assumes that both QEMU
and nspawn tests are run. Particular tests which don't support either
need to explicitly opt out by setting $TEST_NO_{QEMU,NSPAWN}. Do it this
way around to avoid accidentally forgetting to opt in, and to encourage
test authors to at least always support nspawn.

/sys is not guaranteed to exist when a new mount namespace is created.
It is only mounted under conditions specified by
`namespace_info_mount_apivfs`.
Checking if the three available MAC LSMs are enabled requires a sysfs
mounted at /sys, so the checks are moved to before a new mount ns is
created.
This changes the symbolic name for the default gateway from "gateway" to
"_gateway". A new configuration option -Dcompat-gateway-hostname=true|false
is added. If it is set, the old name is also supported, but the new name
is used as the canonical name in either case. This is intended as a temporary
measure to make the transition easier, and the option should be removed
after a few releases, at which point only the new name will be used.
The old "gateway" name mostly works OK, but hasn't gained widespread acceptance
because of the following (potential) conflicts:
- it is completely legal to have a host called "gateway"
- there is no guarantee that "gateway" will not be registered as a TLD, even
though this currently seems unlikely. (Even then, there would be no
conflict except for the case when the top-level domain itself was being resolved.
The "gateway" or "_gateway" labels have only special meaning when the
whole name consists of a single label, so resolution of any subdomain
of the hypothetical gateway. TLD would still work OK. )
Moving to "_gateway" avoids those issues because underscores are not allowed
in host names (RFC 1123, §2.1) and avoids potential conflicts with local or
global names.
v2:
- simplify the logic to hardcode "_gateway" and allow
-Dcompat-gateway-hostname=true as a temporary measure.
Cache client metadata, in order to be improve runtime behaviour under
pressure.
This is inspired by @vcaputo's work, specifically:
https://github.com/systemd/systemd/pull/2280
That code implements related but different semantics.
For a longer explanation what this change implements please have a look
at the long source comment this patch adds to journald-context.c.

As side effect, this corrects the journal's rate limiter feature: we now
always use the unit name as key for the ratelimiter.
These are similar to memdup() and newdup(), but reserve one extra NUL
byte at the end of the new allocation and initialize it. It's useful
when copying out data from fixed size character arrays where NUL
termination can't be assumed.
Let's be a bit stricter in what we end up logging: ignore invalid unit
name specifications. Let's validate all input!
As we ignore unit names passed in from unprivileged clients anyway the
effect of this additional check is minimal.
(Also, no need to initialize the identifier/unit_id fields of stream
objects to NULL if empty strings are passed, the default is NULL
anyway...)
When we create a log stream connection to journald, we pass along the
unit ID. With this change we do this only when we run as system
instance, not as user instance, to remove the ambiguity whether a user
or system unit is specified. The effect of this change is minor:
journald ignores the field anyway from clients with UID != 0. This patch
hence only fixes the unit attribution for the --user instance of the
root user.
