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.
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.
When visiting the tail-reload page, for a short amount of time the
"unscrolled" version is shown. To circumvent that, let's scroll down
immediately at the first possibility to fill the gap between the loading
of the document and the first AJAX request coming in.

There are quite a lot of build outputs which have lines with a length
exceeding the width of the taillog <pre/> and thus visually produce more
lines than 50. This causes the tail "box" to change height frequently
and to get to the bottom you need to scroll down.
We now set a fixed line-height to 120% of the font size and cap the
maximum height based on that value (50 * 1.2 = 60). It's probably not
nice to override the line-height, but max-lines is currently only
available using browser-specific property names. But after all it's just
for the tail output, if people complain about the line-height, we can
still change it :-)

We're just implicitly escaping the tail content by not using .load() but
explicitly setting the text content using .text(), so that escaping
isn't needed on our side.
This should get rid of a few formatting errors and possibly XSS if
someone manages to place JS code in the tail of a build and manages to
lurk a user to that tail output.

Like eval IDs, build IDs don't convey useful information.
Also, make the job name link to the build rather than the job. When
people click on a build, they expect to go to the build page, not the
job page.
Scheduling is mostly based on jobset shares these days. So showing and
sorting by priority just wastes space and gives the incorrect
impression that Hydra executes builds in the order shown on the queue
page.
