John Ericson 5cc22e3370 Clarify docs on deleting generations, including fixing a mistake
Deleting store info corrected (there is a foot-gun in Nix with
`--delete-generations old`!)

Also a few things are cleaned up based on feedback.

weren't included.

John Ericson 469d06f9bc Split out worker protocol template definitions from declarations
This is generally a fine practice: Putting implementations in headers
makes them harder to read and slows compilation. Unfortunately it is
necessary for templates, but we can ameliorate that by putting them in a
separate header. Only files which need to instantiate those templates
will need to include the header with the implementation; the rest can
just include the declaration.

This is now documenting in the contributing guide.

Also, it just happens that these polymorphic serializers are the
protocol agnostic ones. (Worker and serve protocol have the same logic
for these container types.) This means by doing this general template
cleanup, we are also getting a head start on better indicating which
code is protocol-specific and which code is shared between protocols.

Add description for file system objects (#8500)
While this is not actually a notion in the implementation, it is
explicitly described in the thesis and quite important for understanding
how the store works.

Valentin Gagarin db680e0e57
refine wording on the purpose of the Nix language
packages and configurations are not really a concept in Nix or the Nix language. the idea of transforming files into other files clearly captures what it's all about, and the new phrasing should make the term "derivation" more obvious both in terms of meaning and origin.

primops: lazy evaluation of replaceStrings replacements
The primop `builtins.replaceStrings` currently always strictly evaluates the
replacement strings, however time and space are wasted for their computation
if the corresponding pattern do not occur in the input string. This commit
makes the evaluation of the replacement strings lazy by deferring their
evaluation to when the corresponding pattern are matched and memoize the result
for efficient retrieval on subsequent matches.

The testcases for replaceStrings was updated to check for lazy evaluation
of the replacements. A note was also added in the release notes to
document the behavior change.

Valentin Gagarin f8620758aa display documentation on manifest files separately
it's probably better not to show the manifest file documentation in the

the table of contents a bit.

  experimental, and if so what experimental feature does it depend on.)

- Document which installables depend on which experimental features.

  I tried to use the same style (bold warning and block quote) that the
  top of the man page uses.

They are put in the manual separate pages under the new overarching

The settings page just lists the valid experimental feature names (so

pages. It doesn't attempt to describe each experimental feature as that
is too much information for the configuration settings section.

John Ericson 53d0836347 Assemble experimental feature docs outside of Nix itself
Instead of constructing a markdown list in C++ (which involved all sorts
of nasty string literals), export some JSON and assemble it with the
manual build system.

Besides following the precedent set with other dumped data, this is a
better separate of content and presentation; if we decide for example we
want to display this information in a different way, or in a different
section of the manual, it will become much easier to do so.
