097df453da test: do not use last cap from kernel in test-cap-list
The new test-cap-list introduced in commit 2822da4fb7 uses the included
table of capabilities. However, it uses cap_last_cap() which probes the kernel
for the last available capability. On an older kernel (e.g. 3.10 from RHEL 7)
that causes the test to fail with the following message:

    Assertion '!capability_to_name(cap_last_cap()+1)' failed at src/test/test-cap-list.c:30, function main(). Aborting.

Fix it by exporting the size of the static table and using it in the test
instead of the dynamic one from the current kernel.

Tested by successfully running ./test-cap-list and the whole `make check` test
suite with this patch on a RHEL 7 host.

10f9c75519 machined: beef up machined image listing with creation/modification times of subvolumes
We make use of the btrfs subvol crtime for this, and for gpt images of a

0254e9448f util: fix strict aliasing violations in use of struct inotify_event v5
There is alot of cleanup that will have to happen to turn on
-fstrict-aliasing, but I think our code should be "correct" to the rule.

8b169c0fc2 build-sys: move core/build.h → shared/build.h
After all, pretty much all our tools include it, and it should hence be
shared.

Also move sysfs-show.h from core/ to login/, since it has no point to
exist in core.

cd61c3bfd7 machined/machinectl: add logic to show list of available images
This adds a new bus call to machined that enumerates /var/lib/container

        - directory trees

72648326ea import: add new minimal tool "systemd-import" for pulling down foreign containers and install them locally
This adds a simply but powerful tool for downloading container images
from the most popular container solution used today. Use it like
this:

       # systemd-import pull-dck mattdm/fedora
       # systemd-nspawn -M fedora

This will donwload the layers for "mattdm/fedora", and make them
available locally as /var/lib/container/fedora.

The tool is pretty complete, as long as it's only about pulling down
images, or updating them. Pushing or searching is not supported yet.

ba774317ac Treat a trailing backslash as an error
Commit a2a5291b3f changed the parser to reject unfinished quoted
strings. Unfortunately it introduced an error where a trailing
backslash would case an infinite loop. Of course this must fixed, but
the question is what to to instead. Allowing trailing backslashes and
treating them as normal characters would be one option, but this seems
suboptimal. First, there would be inconsistency between handling of
quoting and of backslashes. Second, a trailing backslash is most
likely an error, at it seems better to point it out to the user than
to try to continue.

Updated rules:
ExecStart=/bin/echo \\ → OK, prints a backslash
ExecStart=/bin/echo \ → error
ExecStart=/bin/echo "x → error
ExecStart=/bin/echo "x"y → error

e40872fc53 path-util: fix breakage in path_is_mount_point
This fixes 2 problems introduced by 6feeeab0bc:

1) If name_to_handle_at returns ENOSYS for the child, we'll wrongly
return -ENOSYS when it returns the same for the parent. Immediately
jump to the fallback logic when we get ENOSYS.

2) If name_to_handle_at returns EOPNOTSUPP for the child but suceeds
for the parent, we'll be comparing an uninitialized value (mount_id) to
an initialized value (mount_id_parent). Initialize the mount_id
variables to invalid mount_ids to avoid this.

ee05e7795b core: use raw_clone instead of fork in signal handler
fork() is not async-signal-safe and calling it from the signal handler
could result in a deadlock when at_fork() handlers are called. Using
the raw clone() syscall sidesteps that problem.

The tricky part is that raise() does not work, since getpid() does not
work. Add raw_getpid() to get the real pid, and use kill() instead of
raise().

6feeeab0bc path: make the check for unsupported name_to_handle_at symmetric
If child supports, but the parent does not, or when the child does
not support, but the parent does, assume the child is a mount point.

Only if neither supports use the fallback.

20b63d12b5 util: in make_stdio() use dup2() rather than dup3()
dup3() allows setting O_CLOEXEC which we are not interested in. However,
it also fails if called with the same fd as input and output, which is
something we don't want. Hence use dup2().

Also, we need to explicitly turn off O_CLOEXEC for the fds, in case the
input fd was O_CLOEXEC and < 3.

c4e34a612c nspawn: allow spawning ephemeral nspawn containers based on the root file system of the OS
This works now:

        # systemd-nspawn -xb -D / -M foobar

Which boots up an ephemeral container, based on the host's root file
system. Or in other words: you can now run the very same host OS you
booted your system with also in a container, on top of it, without
having it interfere. Great for testing whether the init system you are
hacking on still boots without reboot the system!
