Secondly: let's port this to use read_line(), i.e. the new way to read
lines from a file in a safe, bounded way.
Thirdly: let's strip leading/trailing whitespace from what we are
reading. Given that we are already pretty lenient what we read (comments
and empty lines), let's be permissive regarding whitespace too.
Fourthly: let's actually validate the hostname when reading it. So far
we tried to make it valid, but that's not always possible (for example,
we can't make an empty hostname valid, ever).

fd-util: add new acquire_data_fd() API helper
All this function does is place some data in an in-memory read-only fd,
that may be read back to get the original data back.
Doing this in a way that works everywhere, given the different kernels
we support as well as different privilege levels is surprisingly
complex.

core: clean up config_parse_exec_input() a bit
Mostly coding style fixes, but most importantly, initialize
c->std_input only after we know the free_and_strdup() invocation
succeeded, so that we don't leave half-initialized fields around on
failure.

execute: check whether we are actually on a TTY before doing TIOCSCTTY
Given that Linux assigns the same ioctl numbers ot multiple subsystems,
we should be careful when invoking ioctls, so that we don't end up
calling something we wouldn't want to call.

fd-util: add new helper move_fd() and make use of it
We are using the same pattern at various places: call dup2() on an fd,
and close the old fd, usually in combination with some O_CLOEXEC
fiddling. Let's add a little helper for this, and port a few obvious
cases over.

nspawn: make recursive chown()ing logic safe for being aborted in the middle
We currently use the ownership of the top-level directory as a hint
whether we need to descent into the whole tree to chown() it recursively
or not. This is problematic with the previous chown()ing algorithm, as
when descending into the tree we'd first chown() and then descend
further down, which meant that the top-level directory would be chowned
first, and an aborted recursive chowning would appear on the next
invocation as successful, even though it was not. Let's reshuffle things
a bit, to make the re-chown()ing safe regarding interruptions:
a) We chown() the dir we are looking at last, and descent into all its
children first. That way we know that if the top-level dir is
properly owned everything inside of it is properly owned too.
b) Before starting a chown()ing operation, we mark the top-level
directory as owned by a special "busy" UID range, which we can use to
recognize whether a tree was fully chowned: if it is marked as busy,
it's definitely not fully chowned, as the busy ownership will only be
fixed as final step of the chowning.

core/cgroup: assigning empty string to Delegate= resets list of controllers (#7336)
Before this, assigning empty string to Delegate= makes no change to the
controller list. This is inconsistent to the other options that take list
of strings. After this, when empty string is assigned to Delegate=, the
list of controllers is reset. Such behavior is consistent to other options
and useful for drop-in configs.
Closes #7334.
