tmpfiles: use common macro for a set of specifiers
This adds %q, %A and %M specifiers to tmpfiles:
- %A and %M were previously added to tmpfiles.d man page, but not to specifier_table
- %q is added via COMMON_SYSTEM_SPECIFIERS

importd: allow activation in early boot, and make it socket activatable
Previously, importd was only accessible via D-Bus, which required it to
be a late boot service. Now that we have Varlink we can rearrange things
to become early-boot activated, just after the image directories are
mounted.
This will later allow us to have generator that auto-downloads images on
boot.
varlink: add varlink_many_*() helpers that send messages to a set of connections at once
If we have a Varlink interface that allows man subscribers to the same
source of events we typically want to notify all of them at once with
the same message.
Let's add some helpers for this purpose: varlink_many_*() can be used to
send messages, similar to the corresponding varlink_*() calls, but they
take a Set of Varlink objects and we issue the operation on every
connection once.
This ports over one existing case where this is beneficial, but the main
user for this is supposed to be importd later.
Let's properly return the measurement flag tristate, rather than a
boolean. Otherwise we'll mistake "nothing to measure" as "not measured",
which are two different things, and means we'll miscombine the flag
later, claiming to userspace that we measured no dtb data even if there
was.

core: do not filter out write() if required in the very late stage

Before 12001b1bf067339db089d52e08fd0b4c6a9945df, the timestamp is sent

Note the invocation will still fail if write() is filtered by seccomp.
But, that is an old issue since Type=exec is introduced

Fix two problems of the keyboard of RedmiBook Pro 15 2022.
- Enter key in the main area was mapped to KP_Enter.
- When Fn is locked (to use F1-F12 without pressing Fn),
Right Ctrl was mapped to Menu. Keeping it as Right Ctrl is more useful.

network/ndisc: do not override conflicting static routes
We have already ignored conflicting address configurations requested by
NDisc protocol. See ndisc_request_address().
Let's follow the same rule for routes. That is, if there are conflicting
static routes configured or requested, do not override them by NDisc.
Also, swap the order of checking existing route and existing request.

core: verify WorkingDirectory= is outside of API VFS only under mount namespacing
The purpose of the check is to prevent leaking API VFS fds
from host into a mount namespace/container. When mountns
is not used at all, the check is pointless and causes
inconvenience. E.g. file managers might need to be spawned
under those directories, and they surely won't run in mountns.

terminal-util: several cleanups for ColorMode
- introduce or rename usual enum values _MAX and _INVALID,
- introduce and use string table lookup functions,
- split out implementation of get_color_mode() to _impl(),
- add tests for get_color_mode().
tree-wide: fix type of read() return variable at a couple of places
read() returns ssize_t (i.e. 64bit typically). We assigned it to int
variables in some cases (i.e. 32bit typically). Let's not be so sloppy,
and not accidentally drop 32bit on the floor.
(of course, this is not an issue IRL since we'll not have allocations
above 2^32 ever we could read into, but still, let's clean this up)
vmspawn: by default, let machined register a cgroup for VMs
This mimics what we do in nspawn: if registration is enabled we'll let
machined allocate a scope unit for us. When --keep-unit is used we'll
register without creating a new scope.
This brings behaviour more inline with what nspawn does, exposing the
same sets of options.
machined: support allocating a scope for machines if needed via varlink
On dbus we have two apis: one for registering a new machne when the
client already has a cgroup (RegisterMachine()) and one where it doesn't
and machined shall create it (CreateMachine()).
Let's add the same for the varlink api. To simplify things we just
implement it via a boolean flag to the existign RegisterMachine()
varlink call, since the differences are mostly minor otherwise.
machined: allow unprivileged registration of VMs/containers
Now that we have a concept of unprivileged VMs and containers, let's
allow unprivileged clients to register with machined too – subject to
Polkit permissions.

core: expose PrivateTmp=disconnected
As discussed in https://github.com/systemd/systemd/pull/32724#discussion_r1638963071
I don't find the opposite reasoning particularly convincing.
We have ProtectHome=tmpfs and friends, and those can be
pretty much trivially implemented through TemporaryFileSystem=
too. The new logic brings many benefits, and is completely generic,
hence I see no reason not to expose it. We can even get more tests
for the code path if we make it public.
install: collect more install_changes_add() errors
We so far collected most unexpected errors from install_changes_add()
and propagated them – but for some invocations we forgot to do that. Add
that, and take care we only propagated unexpected errors (i.e. ENOMEM
and such), but treat expected errors as before.

test: skip test-cgroup-id on ENOSYS from cg_cgroupid_open
Most container managers will block open_by_handle_at with seccomp to
mitigate a container escape attack. LXD in particular returns ENOSYS
rather than e.g. EPERM like nspawn. Skip this test if we get ENOSYS
from open_by_handle_at via cg_cgroupid_open.
meson: bpf: propagate 'sysroot' for cross compilation
During cross-compilation of systemd, the compiler used to build the bpf's needs
to be pointed at the correct include searchpath. Which can be done by passing
the corresponding directory in through the cflags; for example in yocto/bitbake
this would work: CFLAGS += "--sysroot=${STAGING_DIR_TARGET}"

busctl: send BUSERROR= to caller via sd_notify() protocol
varlinkctl has this nice feature that it sends the varlink error it gets
via sd_notify() to the caller. With previous commits this information
is collected and exposed in "systemctl status".
Let's make sure we can provide the same in busctl: also propagate errors
the same way.
Most of our enums are mapped to strings that use dashes ("-") as word
separators, i.e. "foo-bar-baz". However, Varlink enums do not allow "-"
as separator, see:
https://varlink.org/Interface-Definition
Hence, let's add some simple glue to automatucally turn "-" into "_" for
use when serializing our enums.
varlinkctl: add --graceful= option for optionally marking some errors as successes
This is generally useful, but in some cases particularly: when
implementing enumeration calls that use the "more" flag to return
multiple replies then for the first reply we need to return an error in
case the list of objects to enumerate is empty, usually so form of
"NoSuchXYZ" error. In many cases this shouldn't really be treated as
error, as an empty list probably more than not is as valid as a list
with one, two or more entries.
varlink: add helper that validates a qualified Varlink symbol name
Qualified Varlink symbol names are the combination of an interface name,
followed by a dot, followed by a symbol name. It's a primary concept,
after all it's what we send over the wire for method calls and get back
for error returns.
