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().
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.
Otherwise, 99-default.link may introduce something like the
following warnings:

Follow-up for 6c35ea5ef0.
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*.)
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.

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.
Only if we create a file we know for sure that it is empty and hence our
sparse file logic of skipping over NUL bytes can can work. If we hwoever
are called to write data to some existing file/block device, we must do
regular writes to override everything that might be in place before.
Hence, conditionalize sparse file writing on the write offset not being
configured (which is how we internally distinguish write to existing
file and write to new file)
Previously we only allows http/https urls, let's open this up a bit.
Why? Because it makes testing *so* *much* *easier* as we don't need to
run a HTTP server all the time.
CURL mostly abstracts the differences of http/https away from us, hence
we can get away with very little extra work.
