this is a how-to guide which should not be in the reference manual.
it also refers to `nix-env`, which should not be the first thing readers
of the reference manual encounter, as it behaves very differently in
spirit from the rest of Nix.

slightly reword the documentation to be more concise and informative.

John Ericson 259e328de8 Introduce notion of a test group, use for CA tests
Grouping our tests should make it easier to understand the intent than
one long poorly-arranged list. It also is convenient for running just
the tests for a specific component when working on that component.

We need at least one test group so this isn't dead code; I decided to
collect the tests for the `ca-derivations` and `dynamic-derivations`
experimental features in groups. Do
```bash
make ca.test-group -jN
```
and
```bash
make dyn-drv.test-group -jN
```
to try running just them.

I originally did this as part of #8397 for being able to just the local
overlay store alone. I am PRing it separately now so we can separate
general infra from new features.

John Ericson 0f7242ff87 Test nested sandboxing, and make nicer error
We were bedeviled by sandboxing issues when working on the layered
store. The problem ended up being that when we have nested nix builds,
and the inner store is inside the build dir (e.g. store is
`/build/nix-test/$name/store`, build dir is `/build`) bind mounts
clobber each other and store paths cannot be found.

After thoroughly cleaning up `local-derivation-goal.cc`, we might be
able to make that work. But that is a lot of work. For now, we just fail
earlier with a proper error message.

Finally, test this: nested sandboxing without the problematic store dir
should work, and with should fail with the expected error message.

John Ericson e072e18475 Fix race condition in the language tests
When we pipe to `>(...)` like that, we unfortunately don't wait for the
process to finish. Better to just substitute the file.

Also, use the "unified" diff output that people (including myself) are
more familiar with, thanks to Git.

Mathnerd314 c70484454f Expanded test suite
* Lang now verifies errors and parse output

* Some new miscellaneous tests

* Easy way to update the tests

* Document workflow in manual

* Use `!` not `~` as separater char for sed

  It is confusing to use `~` when we are talking about paths and home
  directories!

* Test test suite itself (`test/lang-test/infra.sh`)

Additionally, run shellcheck on `tests/lang.sh` to help ensure it is
correct, now that is is more complex.

John Ericson 903700c5e1 Simplify ContentAddress
Whereas `ContentAddressWithReferences` is a sum type complex because different
varieties support different notions of reference, and
`ContentAddressMethod` is a nested enum to support that,
`ContentAddress` can be a simple pair of a method and hash.

`ContentAddress` does not need to be a sum type on the outside because
the choice of method doesn't effect what type of hashes we can use.
