Remove some unnecessary configurability, remove all hydra.nixos.org
assumptions, remove some policy (e.g. nix.gc.automatic) that are
orthogonal to hydra.

Chaining paths only works properly when PathPart is used. Before this
fix, the affected URIs bypassed the top-level 'admin' sub.

This reverts commit 71d020735b.
Unfortunately there are still some cases where we need to set Hydra's
concurrency separately. (Ideally, Hydra would start *all* queued
builds in parallel and let Nix take care of everything...)
So now "?compare=<jobset name>" is no longer a hidden feature!
P.S. Encountered this wonderful TemplateToolkit brainfuck again: if
you want to get the number of rows in (say) project.jobsets, you can't
say "project.jobsets.size". That will *usually* give the right
result, except that if there is only one row in project.jobsets, it
will evaluate to 3. Instead you have to use "project.jobsets_rs.count".
Note that on machines that support multiple system types, EACH system type gets the full number of build slots, which is almost certainly not what we want.
You can use the URL
http://<hydra-server>/api/push-github
as GitHub's WebHook URL. Hydra will automatically trigger an
evaluation of all affected jobsets.
External machines can now notify Hydra that it should check a
repository by sending a GET or PUSH request to /api/push, providing a
list of jobsets to be checked and/or a list of repository URLs. In
the latter case, all jobsets that have any of the specified
repositories as an input will be checked.
For instance, you can configure GitHub or BitBucket to send a request
to the URL
http://hydra.example.org/api/push?repos=git://github.com/NixOS/nixpkgs.git
to trigger evaluation of all jobsets that have
git://github.com/NixOS/nixpkgs.git as an input, or to the URL
http://hydra.example.org/api/push?jobsets=patchelf:trunk,nixpkgs:trunk
to trigger evaluation of just the specified jobsets.
Otherwise you can do
ln -s /etc/passwd $out/foo
echo "file misc $out/foo" >> $out/nix-support/hydra-build-products
and get Hydra to serve its /etc/passwd file.
