Now that we have our dedicated "Channels" tab, there is no need anymore
to show redundant information.

We now no longer need that additional join of the build outputs and can
solely use the isChannel column of the Builds table to determine whether
it's a channel build.

This is to properly separate channels from regular jobs and also make
sure that we can always iterate on them, no matter whether the build has
failed. The reason why we were not able to do this until now was because
we were iterating on the build products, and whenever some constituent
of a channel job has failed, we didn't get a build output.
So whenever there is a meta.isHydraChannel, we can now properly
distinguish it from the other jobs.
I still don't have any clue, why "make -C src/sql update-dbix" without
*any* modifications tries to create additional schema definitions. But
I've checked the md5sums of the existing schema definitions and they
don't seem to match, so it seems that they already have been tampered
with.

Now we can provide different channel expressions for one particular
channel build. Not sure yet how this would be useful, but I found it
more appropriate to use a type instead of a subtype of "file".
This should get us consistent with the provious commit.

This is to get a bit more consistency among channel builds but doesn't
do a radical change on the display. Ideally we may want to have a
channel overview with all the constituents and a small help showing how
the user can add the channel.
Unfortunately, this also introduces an inconsistency: We previously used
the *subtype* "channel", but now we're expecting "channel" as the type
of the product, so we need to change this for the channels overview as
well.

It's very similar to "jobs" and the code is pretty much the same, except
that we don't do filtering on it. At least it doesn't waste space for a
filter option when there are usually WAY less channel jobs than ordinary
jobs.

Builds can now emit metrics that Hydra will store in its database and
render as time series via flot charts. Typical applications are to
keep track of performance indicators, coverage percentages, artifact
sizes, and so on.
For example, a coverage build can emit the coverage percentage as
follows:
echo "lineCoverage $pct %" > $out/nix-support/hydra-metrics
Graphs of all metrics for a job can be seen at
http://.../job/<project>/<jobset>/<job>#tabs-charts
Specific metrics are also visible at
http://.../job/<project>/<jobset>/<job>/metric/<metric>
The latter URL also allows getting the data in JSON format (e.g. via
"curl -H 'Accept: application/json'").
Without an index on (machine, stoptime desc), this requires a
sequential scan. And adding a whole index for this seems
overkill. (Possibly the queue runner could maintain this info more
efficiently.)
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.
