b51e161af5 Cleanup ContentAddressMethod to match docs
The old `std::variant` is bad because we aren't adding a new case to
`FileIngestionMethod` so much as we are defining a separate concept ---
store object content addressing rather than file system object content
addressing. As such, it is more correct to just create a fresh
enumeration.

5b53d8fec3 Factor out GC initialization code
This is not really part of the evaluator: it is just an integration
between Boehm GC and Boost coroutines usable for any purpose. The
evaluator (merely) optionally uses it.

f91f34aa65 bdwgc 8.2.4 has sp_corrector
> Support client-defined stack pointer adjustment before thread stack push

-- https://github.com/ivmai/bdwgc/releases/tag/v8.2.4

This fixes an inaccuracy in cc6f315252,
in the update to Nixpkgs 24.05 https://github.com/NixOS/nix/pull/10835

After this fixup, the build log won't ask for an upgrade, and we'll be
able to collect when a coroutine exists, e.g. during filterSource.

cc6f315252 nix: Disable GC during coroutine when bdwgc < 8.4
This re-enables support for older bwdgc versions without complicating
the code too much.
Coroutines generally only interfere with GC during source filtering,
so it's not too bad of a regression on older bdwgc.
This seems preferable over conditional compilation to enable the patch
etc; we've already spent a lot of complexity budget on this GC-coroutine
interaction...

2477e4e3b8 libexpr: Use GC_set_sp_corrector instead of patch
Manually tested by printing to stderr in both branches (sp in os
stack, or not), and triggering a GC in a filterSource function,
e.g.:

    let
      generateTree = n: if n == 0 then "ha" else { left = generateTree (n - 1); right = generateTree (n - 1); };
    in
      builtins.deepSeq (generateTree 18) ...

Note that the darwin still uses the strategy of disabling GC, despite
having an implementation that compiles. The proper solution will be
enabled and tested later.

Note that Nixpkgs' lib.warn already requires a string coercible

473d2d56fc Remove 100s of CPU time (10%) from build times (1465s -> 1302s)
Result's from Mic92's framework 13th Gen Intel Core i7-1360P:

Before: 3595.92s user 183.01s system 1360% cpu 4:37.74 total
After: 3486.07s user 168.93s system 1354% cpu 4:29.79 total

I saw that boost/lexical_cast was costing about 100s in CPU time on our
compiles. We can fix this trivially by doing explicit template
instantiation in exactly one place and eliminating all other includes of
it, which is a code improvement anyway by hiding the boost.

Nixpkgs). However, impureEnvVars doesn't actually do anything for
builtin:fetchurl, so we can just set it to its historical value.

This missing GC root wasn't much of a problem before, because the

but when unit testing, the construction of `EvalState` doesn't
necessarily happen well before GC runs for the first time.

8433027e35 Build a minimized Nix with MinGW
At this point many features are stripped out, but this works:

- Can run libnix{util,store,expr} unit tests
- Can run some Nix commands

eff90af498 Slight refactors in preparation for #10480
Code operating on store objects (including creating them) should, in
general, use `ContentAddressMethod` rather than `FileIngestionMethod`.

See also dfc876531f which included some
similar refactors.

93d68e18e5 Make outputHashAlgo accept "nar", stay in sync
Now that we have a few things identifying content address methods by
name, we should be consistent about it.

Move up the `parseHashAlgoOpt` for tidiness too.

Discussed this change for consistency's sake as part of #8876

d29786f258 downloadFile(): Remove the "locked" (aka "immutable") flag
This was used in only one place, namely builtins.fetchurl with an
expected hash. Since this can cause similar issues as described
in #9814 and #9905 with the "locked" flag for fetchTarball and fetchTree,
let's just remove it.

Note that if an expected hash is given and the hash algorithm is
SHA-256, then we will never do a download anyway if the resulting
store path already exists. So removing the "locked" flag will only
cause potentially unnecessary HTTP requests (subject to the tarball
TTL) for non-SHA-256 hashes.

910211f9ff avoid markdown which the repl's :doc cannot handle
code blocks, if not surrounded by empty lines, have the language
tags (in these cases, always `nix`) show up in the output of :doc.

for example:

  nix-repl> :doc builtins.parseFlakeRef
  Synopsis: builtins.parseFlakeRef flake-ref

    Parse a flake reference, and return its exploded form.

    For example: nix builtins.parseFlakeRef
    "github:NixOS/nixpkgs/23.05?dir=lib"  evaluates to: nix { dir =
    "lib"; owner = "NixOS"; ref = "23.05"; repo = "nixpkgs"; type =
    "github"; }

is now instead:
  nix-repl> :doc builtins.parseFlakeRef
  Synopsis: builtins.parseFlakeRef flake-ref

    Parse a flake reference, and return its exploded form.

    For example:

      | builtins.parseFlakeRef "github:NixOS/nixpkgs/23.05?dir=lib"

    evaluates to:

      | { dir = "lib"; owner = "NixOS"; ref = "23.05"; repo = "nixpkgs"; type = "github"; }

Slight cleanup of builtins.derivation outputHashAlgo logic (#10417)
This was part of approved PR #10021. Unfortunately that one is stalled
on a peculiar Linux test timeout, so trying to get bits of it merged
first to bisect failure.

c145ce0e1a realiseContext: Remove no-op replacements
A possible use of them might have been to figure out the paths
(which can now be retrieved with maybePathsOut), but I have
not found evidence that it was used this way, and it would have
been broken, because non-CA outputs weren't recorded in the map.
