be3444f119 execute: make ExecStatus dump more useful by showing passed time 
Let's show the runtimes of our commands and preparations for them. It's
actually quite interesting, we sometimes are irritatingly slow with our
handoffs.

3c1d1ca146 manager: switch service unit type over to using new handoff timestamping logic 
Also: rename Handover → Handoff. I think it makes it clearer that this
is not really about handing over any resources, but that the executor is
out off the game from that point on.

12001b1bf0 execute: send handoff timestamps from executor to service manager 
This changes the executor to systematically send handoff timestamps to
the service manager if a socket for that is supplied. This drops the
code that did this via Type=exec messages, and reverts that part to the
old behaviour before 93cb78aee2.

Benefits of this approach:

1. We can collect the handoff for any command we fork off, regardless
   if it's ExecStart= something else, regardless whether it's Type=exec,
   Type=simple or some any other service type, regardless of the unit
   type.

2. We collect both CLOCK_REALTIME and CLOCK_MONOTONIC, as we do for the
   other process timestamps.

3. It's entirely backwards compatible, as this doesn't change the
   protocol between service manager and executor, but just extends it.

817062e621 manager: add socket for receiving handoff timestamps from forked children 
This adds an AF_UNIX socket pair to the manager that we can collect
handoff timestamp messages on.

The idea is that forked off children send a datagram with a timestamp
and we use its sender PID to match it against the right forked off
process.

This part only implements the receiving side: a socket is created, and
listened on. Received datagrams are parsed, verified and then dispatched
to the interested units.

33fc8b0d95 core: fix assertions in manager_dispatch_user_lookup_fd() 
assert_se() should not be used here, these checks are paranoia only and
have no side-effect after all.

hence fix this to use assert(), or in fact ASSERT_PTR()

dc3058e490 systemctl: list-jobs: interchange 'waiting for' and 'blocking' in output 
The current output of 'systemctl list-jobs' with the --after and/or --before
switches seems backwards. With artificial units

# check-oil.service
[Unit]
Description=Check the oil level
Before=engine-ready.target

# fill-gas.service
[Unit]
Description=Fill the tank with gasoline
Before=engine-ready.target

# engine-ready.target
[Unit]
Description=The engine is ready

[Unit]
Description=Start the engine!
After=engine-ready.target
Wants=engine-ready.target

running 'systemctl list-jobs --before --after' produces

JOB UNIT                                              TYPE  STATE
93  check-oil.service                                 start running
└─      waiting for job 94 (engine-ready.target/start)   -     -
102 fill-gas.service                                  start running
└─      waiting for job 94 (engine-ready.target/start)   -     -
94  engine-ready.target                               start waiting
└─      waiting for job 111 (start-engine.service/start) -     -
└─      blocking job 93 (check-oil.service/start)        -     -
└─      blocking job 102 (fill-gas.service/start)        -     -
111 start-engine.service                              start waiting
└─      waiting for job 1 (multi-user.target/start)      -     -
└─      blocking job 94 (engine-ready.target/start)      -     -

Obviously, job 93 is not waiting for job 94, but rather blocking it.
