Prior, tests would all fail to build, causing, roughly, the following
error (roughly, because I added some debug log messages :)):

The hydra-queue-runner opens a connection to the builder. If the
builder is 'localhost' it starts `nix-store`, otherwise it starts
'ssh'.
Currently, if the hydra-queue-runner can not start `nix-store` (not in
the PATH for instance), the error message is:
cannot connect to ‘localhost’: error: cannot start ssh: No such file
or directory
This is not useful since ssh is actually not started:/
With this patch the error message is now:
cannot connect to ‘localhost’: error: cannot start nix-store: No such file
or directory
Some time ago the data structure for maintainer descriptions in
`nixpkgs` changed from a simple attr set with maintainer emails as
values to an attribute set where the maintainer' nick is associated to
an attribute set with email, GitHub handle and full name.
Hydra can either parse a Nix list or fetches `shortName` from the
associated attribute set (which is used for `meta.licenses` as each
value in it contains a `shortName`). This behavior needs to be
replicated for maintainers to retrieve the emails for `hydra-notify`.
This change is backwards-compatible since `queryMetaStrings` is still
able to understand lists, so old versions of `nixpkgs` or packages using
the old maintainer data structure remain usable.
This is because setting only the initial heap size to more than
the default value (or the configured value) will cause all initial evals
until maxHeapSize expands to the given value to abort.
The 1.1 multiplier comes from the the configured defaults on NixOS' hydra,
and from the previous multiplier used before
7876cf677c.
This is caused by the autoconf check for `nix-store` which is equivalent
to running this:
```
$ nix-store --timeout 123 -q
```
This would open the pager on a 2.1.1 version of nix.
```
$ nix-store --version
nix-store (Nix) 2.1.1
```
Setting `PAGER` to `cat` ensures the pager doesn't block the
configurePhase.
```
$ PAGER=cat nix-store --timeout 123 -q
```
In order to access protected or private repositories. Using the target
repository URL along with the merge-request ref instead of the source
repository url and branch is necessary to avoid running into issues if
the source repository is not actually accessible to the user Hydra is
authenticating as.
Thanks Alexei Robyn for this patch.
