7d5dd5e0cf util: modernize loop_read() and loop_write() a bit

28c758de94 Revert "manager: print ephemeral information about running jobs' timeouts"
This reverts commit 2cba2e0352.

It breaks bootup with dracut, the transition to the real rootfs fails.

d450b6f2a9 manager: add systemd.show_status=auto mode
When set to auto, status will shown when the first ephemeral message
is shown (a job has been running for five seconds). Then until the
boot or shutdown ends, status messages will be shown.

No indication about the switch is done: I think it should be clear
for the user that first the cylon eye and the ephemeral messages appear,
and afterwards messages are displayed.

The initial arming of the event source was still wrong, but now should
really be fixed.

65b3903ff5 journal: guarantee async-signal-safety in sd_journald_sendv
signal(7) provides a list of functions which may be called from a
signal handler. Other functions, which only call those functions and
don't access global memory and are reentrant are also safe.
sd_j_sendv was mostly OK, but would call mkostemp and writev in a
fallback path, which are unsafe.

Being able to call sd_j_sendv in a async-signal-safe way is important
because it allows it be used in signal handlers.

Safety is achieved by replacing mkostemp with open(O_TMPFILE) and an
open-coded writev replacement which uses write. Unfortunately,
O_TMPFILE is only available on kernels >= 3.11. When O_TMPFILE is
unavailable, an open-coded mkostemp is used.

8e33886ec5 Replace mkostemp+unlink with open(O_TMPFILE)
This will only work on Linux >= 3.11, and probably not on all
filesystems. Fallback code is provided.

b28ff39f42 bus: rework bloom filter logic to operate with variable bloom filter

In order to make the bloom filter logic more future proof communicate
bloom filter parameters from the original bus creator to the clients,
and allow them to be variable within certain ranges.

af08d2f9cd bus: add API calls for connecting to starter bus
Add new calls sd_bus_open() and sd_bus_default() for connecting to the
starter bus a service was invoked for, or -- if the process is not a
bus-activated service -- the appropriate bus for the scope the process
has been started in.

36be24c8f8 core: require mounts for the root and working directories
We know that launching a unit will fail if some required directories
haven't been mounted yet. There's no point in starting it just to
have it fail even before it gets a chance to run.

fd08a8403f manager: rearm jobs timer
It would fire just once.

Also fix units from sec to usec as appropriate.

Decrease the switching interval to 1/3 s, so that when the time
remaining is displayed with 1s precision, it doesn't jump by 2s every
once in a while. Also, the system is feels noticably faster when the
status changes couple of times per second instead of every few
seconds.

2cba2e0352 manager: print ephemeral information about running jobs' timeouts
Produces output like:
[  *** ] (1 of 2) A start job is running for slow.service (33s / 1min 30s)

The first nubmer is the time since job start, the second is the job timeout.

b4a11878f2 cryptsetup: Support key-slot option
Debian recently introduced the option key-slot to /etc/crypttab to
specify the LUKS key slot to be used for decrypting the device. On
systems where a keyfile is used and the key is not in the first slot,
this can speed up the boot process quite a bit, since cryptsetup does
not need to try all of the slots sequentially. (Unsuccessfully testing
a key slot typically takes up to about 1 second.)

This patch makes systemd aware of this option.

0bba8d6eb7 build-sys: merge libsystemd-login into libsystemd
A compatibility libsystemd-login library is created which uses
.symver and ifunc magic proposed by Lennart to make programs linked
to the old library name continue to work seamlessly.

Unfortunately the bfd linker crashes:
  https://sourceware.org/bugzilla/show_bug.cgi?id=16467
This will be fixed in binutils 2.25.

As a work-around, gold can be used:
  LDFLAGS=-Wl,-fuse-ld=gold

Unfortunately the switch to pick the linker appeared in gcc 4.8.

This also doesn't work with LLVM:
