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.
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.
These give warnings in Perl >= 5.18:

All successful, non-garbage-collected builds in the evaluation are
passed in a attribute set. So if you declare a Hydra input named
‘foo’ of type ‘eval’, you get a set with members ‘foo.<jobname>’. For
instance, if you passed a Nixpkgs eval as an input named ‘nixpkgs’,
then you could get the Firefox build for x86_64-linux as
‘nixpkgs.firefox.x86_64-linux’.
Inputs of type ‘eval’ can be specified in three ways:
* As the number of the evaluation.
* As a jobset identifier (‘<project>:<jobset>’), which will yield the
latest finished evaluation of that jobset. Note that there is no
guarantee that any job in that evaluation has succeeded, so it might
not be very useful.
* As a job identifier (‘<project>:<jobset>:<job>’), which will yield
the latest finished evaluation of that jobset in which <job>
succeeded. In conjunction with aggregate jobs, this allows you to
make sure that the evaluation contains the desired builds.
This reverts commit 2d7e106d29.
Unfortunately some jobsets still depend on this behaviour. They could
probably do something like "assert system == input.system; ..." but
changing them all is undesirable.
Include information about who changed the build status in notification
emails, and enable optional per-input notification of said committers.

There are jobsets that are evaluated only once, that is, after they've
been evaluated, they're disabled automatically. This is primarily
useful for doing releases: for instance, doing an evaluation with
"officialRelease" set to "true" should be done only once.
