John Ericson b1fa6b3aac Use StoreConfig::getDefaultSystemFeatures for default machine config
We have to oddly make a `StoreConfig` subclass to get it, but
https://github.com/NixOS/nix/pull/9848 will fix that.

The purpose of this is to ensure that, absent an explicit config,
`localhost` includes `ca-derivations` and `recursive-nix` if those
experimental features are enabled.

Very much the complement of #1342, the previous PR.

John Ericson 07cb5d1b7c Use nix::ParsedDerivation::getRequiredSystemFeatures()
A slight dedup, and also ensures that floating CA derivations require a
`ca-derivations` experimental feature. This fixes the scheduling issue
that @SuperSandro2000 found.

John Ericson 70e5469303 Use Nix's Machine type in a mimimal way
This is *just* using the fields from that type, and only where the types
coincide. (There are two fields with different types, `speedFactor` most
interestingly.) No code is reused, so we can be sure that no behavior is
changed.

Once the types are reconciled on the Nix side, then we can start
carefully actually reusing code.

Progress on #1164

John Ericson 2ee0068fdc Do not copy for both stores for now
It has a performance cost, and as the comment says we should be doing
the better solution. We want to land this preparatory change on prod
while the rest is still on staging, so we should just skip it for now.

Skipping it will not affect regular fixed-output and input-addressed
derivations, which are the only ones prod would deal with upon getting
this code.

The main CA derivations support branch will revert this commit so it
still works.

John Ericson 6a54ab24e2 Use factored-out BuildResult serializer
For the record, here is the Nix 2.19 version:
https://github.com/NixOS/nix/blob/2.19-maintenance/src/libstore/serve-protocol.cc,
which is what we would initially use.

It is a more complete version of what Hydra has today except for one
thing: it always unconditionally sets the start/stop times.

I think that is correct at the other end seems to unconditionally
measure them, but just to be extra careful, I reproduced the old
behavior of falling back on Hydra's own measurements if `startTime` is
0.

The only difference is that the fallback `stopTime` is now measured from
after the entire `BuildResult` is transferred over the wire, but I think
that should be negligible if it is measurable at all. (And remember,
this is fallback case I already suspect is dead code.)

John Ericson 3df8feb3a2 Add TODO about setting null instead of empty string in JSON
An empty string is a sneaky way to avoid hard failures --- things that
expect strings still get strings, but it does conversely open the door
up to soft failures (spooky-action-at-a-distance ones because the string
did not have the expected invariants).

"Fail fast" with null will ultimately make the system more robust, but
force us to fix more things up front, and I don't want to change this
without also fixing those things up front, especially as this commit is
for now just part of the the preparatory PR for which this is dead code.

John Ericson 069b7775c5 hydra-eval-jobs: Ensure we have output path if ca-derivations is disabled
Brought up by @thufschmitt in
https://github.com/NixOS/hydra/pull/1316#discussion_r1415111329 . This
makes this closer to what was originally there --- which just dispatched
off the experimental feature rather than the presence/absense of the
output, too.

John Ericson 9ba4417940 Prepare for CA derivation support with lower impact changes
This is just C++ changes without any Perl / Frontend / SQL Schema
changes.

The idea is that it should be possible to redeploy Hydra with these
chnages with (a) no schema migration and also (b) no regressions. We
should be able to much more safely deploy these to a staging server and
then production `hydra.nixos.org`.

queue-runner: only re-sort runnables by prio once per dispatch cycle
The previous implementation was O(N²lg(N)) due to sorting the full
runnables priority list once per runnable being scheduled. While not
confirmed, this is suspected to cause performance issues and
bottlenecking with the queue runner when the runnable list gets large
enough.

This commit changes the dispatcher to instead only sort runnables per
priority once per dispatch cycle. This has the drawback of being less
reactive to runnable priority changes: the previous code would react
immediately, while this might end up using "old" priorities until the
next dispatch cycle. However, dispatch cycles are not supposed to take
very long (seconds, not minutes/hours), so this is not expected to have
much or any practical impact.

Ideally runnables would be maintained in a sorted data structure instead
of the current approach of copying + sorting in the scheduler. This
would however be a much more invasive change to implement, and might
have to wait until we can confirm where the queue runner bottlenecks
actually lie.
