gpt-auto-generator: Use volatile-root by default and automatic logic as fallback
Previously volatile-root was only checked if "/" wasn't backed by a
block device, but the block device isn't necessarily original root block
device (ex: if the rootfs is copied to a ext4 fs backed by zram in the
initramfs), so we always want volatile-root checked.
So shuffle the code around so volatile-root is checked first and
fallback to the automatic logic.
run/mount/systemctl: don't fork off PolicyKit/ask-pw agent when in --user mode
When we are in --user mode there's no point in doing PolicyKit/ask-pw
because both of these systems are only used by system-level services.
Let's disable the two agents for that automaticlly hence.

sd-netlink: drop sd_genl_family_t and introduce GenericNetlinkFamily
Kernel manages each genl family by its name, e.g. "nlctrl" or WG_GENL_NAME,
and its ID (used for nlmsg_type) is determined dynamically when the
corresponding module is loaded.
This commit makes sd-netlink follow the same way; now, sd_genl_family_t
is dropped, and sd_genl_message_new() takes a genl family name. Each
genl family is resolved when it is used first time, and its information
is stored in GenericNetlinkFamily.

sd-netlink: split type system for nfnl
This makes the root type system for nfnl indexed by subsystem, and
itroduces a next level type system for each subsystem. The second
level type systems are indexed by message types correspond to each
subsystem.
Let's only assign boolean values to a boolean variable.
Unit's condition_result is not of type ConditionResult, slightly
confusingly. Let's hence not assign one of ConditionResult's values to
it, but simple booleans.
This effectively doesn't make a difference, since CONDITION_ERROR is
true when cast to bool. But it's still ugly to rely on that. And
confusing.

core: Add information on which condition failed to job skipped format string
When a job is skipped, it's useful to know exactly which condition failed so
let's add this information to the error message. Because we now return an
allocated string from job_done_message_format(), make sure we strdup() the
other formats as well so the caller can safely free the string returned by
job_done_message_format().
homed: always align home file systems to 4K boundaries
Let's carefully align all home file systems to 4K sector boundaries.
It's the safest thing to do, to ensure good perfomance on 4K sector
drives, i.e. today's hardware.
Yes, this means we'll waste 3.5K when resizing home dirs, but I think we
can live with that.
This ensures both the offsets where we start and the sizes of the file
systems/partitions/disk images are multiples of 4K always, both when
creating a new image and when resizing things.
Note that previously we aligned everything to 1024, but weren't quite as
careful.

core: Check unit start rate limiting earlier
Fixes #17433. Currently, if any of the validations we do before we
check start rate limiting fail, we can still enter a busy loop as
no rate limiting gets applied. A common occurence of this scenario
is path units triggering a service that fails a condition check.
To fix the issue, we simply move up start rate limiting checks to
be the first thing we do when starting a unit. To achieve this,
we add a new method to the unit vtable and implement it for the
relevant unit types so that we can do the start rate limit checks
earlier on.
The verity partition types are per-architecture already, and they contain the
hash data independently of whether we are on a given architecture. (Or in other
words, we would make *use* this partition on some architecture, but the
contents always *exists*.)
json: rework JSON_BUILD_XYZ() macros to use compound literals instead of compound statements
Compound statements is this stuff: ({ … })
Compound literals is this stuff: (type) { … }
We use compound statements a lot in macro definitions: they have one
drawback though: they define a code block of their own, hence if macro
invocations are nested within them that use compound literals their
lifetime is limited to the code block, which might be unexpected.
Thankfully, we can rework things from compound statements to compund
literals in the case of json.h: they don't open a new codeblack, and
hence do not suffer by the problem explained above.
The interesting thing about compound statements is that they also work
for simple types, not just for structs/unions/arrays. We can use this
here for a typechecked implicit conversion: we want to superficially
typecheck arguments to the json_build() varargs function, and we do that
by assigning the specified arguments to our compound literals, which
does the minimal amount of typechecks and ensures that types are
propagated on correctly.
We need one special tweak for this: sd_id128_t is not a simple type but
a union. Using compound literals for initialzing that would mean
specifiying the components of the union, not a complete sd_id128_t. Our
hack around that: instead of passing the object directly via the stack
we now take a pointer (and thus a simple type) instead.
Nice side-effect of all this: compound literals is C99, while compound
statements are a GCC extension, hence we move closer to standard C.

macro: handle overflow in ALIGN_TO() somewhat reasonably
The helper call rounds up to next multiple of specified boundary. If one
passes a very large value as first argument, then there might not be a
next multiple. So far we ignored that. Let's handle this now and return
SIZE_MAX in this case, as special indicator that we reached the end.
Of course, IRL this should not happen. With this new change we at least
do something somewhat reasonable, leaving it to the caller to handle it
further.
