b1a75c7f63 getQueuedBuilds(): Handle dependent builds first 
If a build A depends on a derivation that is the top-level derivation
of some build B, then we should process B before A (meaning we
shouldn't make the derivation runnable before B has been
added). Otherwise, the derivation will be "accounted" to A rather than
B (so the build step will show up in the wrong build).

Also, keep track of timeouts in the database as a distinct build
status.

b91a616520 Automatically retry aborted builds 
Aborted builds are now put back on the runnable queue and retried
after a certain time interval (currently 60 seconds for the first
retry, then tripled on each subsequent retry).

42e7301c08 Add status dump facility 
Doing

  $ psql hydra -c 'notify dump_status'

will cause hydra-queue-runner to dump some internal status info on
stderr.

c08883966c Use PostgreSQL notifications for queue events 
Hydra-queue-runner now no longer polls the queue periodically, but
instead sleeps until it receives a notification from PostgreSQL about
a change to the queue (build added, build cancelled or build
restarted).

Also, for the "build added" case, we now only check for builds with an
ID greater than the previous greatest ID. This is much more efficient
if the queue is large.

d72a88b562 Don't try to handle SIGINT 
It just makes things unnecessarily complicated. We can just exit
without cleaning anything up, since the only thing to do is unmark
builds and build steps as busy. But we can do that by having systemd
call "hydra-queue-runner --unlock" from ExecStopPost.

I.e. don't use Nix's failed paths feature anymore. Easier to keep

c93aa92563 Create BuildSteps race-free 
If multiple threads create a step for the same build, they could get
the same "max(stepnr)" and allocate conflicting new step numbers. So
lock the BuildSteps table while doing this. We could use a different
isolation level, but this is easier.

8b12ac1f6d Basic remote building 
This removes the need for Nix's build-remote.pl.

Build logs are now written to $HYDRA_DATA/build-logs because
hydra-queue-runner doesn't have write permission to /nix/var/log.

214b95706c On SIGINT, shut down the builder threads 
Note that they don't get interrupted at the moment (so on SIGINT, any
running builds will need to finish first).
