Eelco Dolstra 128910ba23 Separate cgroup support from auto-uid-allocation 
The new experimental feature 'cgroups' enables the use of cgroups for
all builds. This allows better containment and enables setting
resource limits and getting some build stats.

Robert Hensing 7e162c69fe derivation-goal: Fix requires non-existing output error 
It occurred when a output of the dependency was already available,
so it didn't need rebuilding and didn't get added to the
inputDrvOutputs.
This process-related info wasn't suitable for the purpose of finding
the actual input paths for the builder. It is better to do this in
absolute terms by querying the store.

libstore: link to aws-crt-cpp 
This change is needed to support aws-sdk-cpp 1.10 and newer.

I opted not to make this dependent on the sdk version because
the crt dependency has been in the interface of the older
sdk as well, and it was only coincidence that libstore didn't
make use of any privately defined symbols directly.

Restrict readFile context to references that appear in the string 
When calling `builtins.readFile` on a store path, the references of that
path are currently added to the resulting string's context.

This change makes those references the *possible* context of the string,
but filters them to keep only the references whose hash actually appears
in the string, similarly to what is done for determining the runtime
references of a path.

Eelco Dolstra 2fde7e0108 Split auto UID allocation from cgroups 
Cgroups are now only used for derivations that require the uid-range
range feature. This allows auto UID allocation even on systems that
don't have cgroups (like macOS).

Also, make things work on modern systems that use cgroups v2 (where
there is a single hierarchy and no "systemd" controller).

Valentin Gagarin f7ab93b068 manual: build action -> build task 
after discussing this with multiple people, I'm convinced that "build
task" is more precise: a derivation is not an action, but inert until it
is built. also it's easier to pronounce.

proposal: use "build task" for the generic concept "description of how
to derive new files from the contents of existing files". then it will
be easier to distinguish what we mean by "derivation" (a specific data
structure and Nix language value type) and "store derivation" (a
serialisation of a derivation into a file in the Nix store).
