John Ericson c6f7d43678 nixpkgs module: Clean up platform options
- `localSystem` is added, it strictly supercedes system

 - `crossSystem`'s description mentions `localSystem` (and vice versa).

 - No more weird special casing I don't even understand

John Ericson bbfa2f9701 lib: Split Darwin into macOS and iOS
I noticed LLVM accepts `ios` as its own OS in platform triples; a
recent change as far as I know. I see it also accepts `macos*` for macOS
(formerly OS X). If it's now customary to distinguish iOS like so
(rather than guessing from the aarch, lets add both so our OSes are
still disjoint, and make Darwin a family instead.

But changing the config everywhere would probably be a mass rebuild, and
I'm not sure how well other software supports OSes besides "darwin", so
I'm keeping that the default name for macOS for now.

Daniel Barlow 9c50ae6898 lib, treewide: Add missing MIPS arches, and fix existing usage
Existing "mips64el" should be "mipsel".

This is just the barest minimum so that nixpkgs can recognize them as
systems - although required for building individual derivations onto
MIPS boards, it is not sufficient if you want to actually build nixos on
those targets

Will Dietz 2dfee94fe7 lib/systems: musl, libc predicates
Note this doesn't actually provide musl support yet,
just improves our "system" code to understand
musl-based triples and non-glibc linux configurations.

John Ericson ad78ba1efa lib: Better use the module type system in platform parsing
I need some module system types here so I can next fix meta-checks for
derivations. I'd like to use a "proper" record type here, but submodule
types seem overkill so holding off with ad-hoc stuff for now. In
practice, all I need for the next step are the `.check` functions so
this is good, especially as the submodule check function is shallow,
saving full inductive type-checking for a later step.

John Ericson d1478c91c3 lib: Allow parsing platform configs with arch of {riscv,wasm}{32,64}
Also add `isRiscv` and `isWasm` predicates.

Convert libs to a fixed-point
This does break the API of being able to import any lib file and get
its libs, however I'm not sure people did this.

I made this while exploring being able to swap out docFn with a stub
in #2305, to avoid functor performance problems. I don't know if that
is going to move forward (or if it is a problem or not,) but after
doing all this work figured I'd put it up anyway :)

Two notable advantages to this approach:

1. when a lib inherits another lib's functions, it doesn't
   automatically get put in to the scope of lib
2. when a lib implements a new obscure functions, it doesn't
   automatically get put in to the scope of lib

Using the test script (later in this commit) I got the following diff
on the API:

  + diff master fixed-lib
  11764a11765,11766
  > .types.defaultFunctor
  > .types.defaultTypeMerge
  11774a11777,11778
  > .types.isOptionType
  > .types.isType
  11781a11786
  > .types.mkOptionType
  11788a11794
  > .types.setType
  11795a11802
  > .types.types

This means that this commit _adds_ to the API, however I can't find a
way to fix these last remaining discrepancies. At least none are
_removed_.

Test script (run with nix-repl in the PATH):

  #!/bin/sh

  set -eux

  repl() {
      suff=${1:-}
      echo "(import ./lib)$suff" \
          | nix-repl 2>&1
  }

  attrs_to_check() {
      repl "${1:-}" \
          | tr ';'  $'\n' \
          | grep "\.\.\." \
          | cut -d' ' -f2 \
          | sed -e "s/^/${1:-}./" \
          | sort
  }

  summ() {
      repl "${1:-}" \
          | tr ' ' $'\n' \
          | sort \
          | uniq
  }

  deep_summ() {
      suff="${1:-}"
      depth="${2:-4}"
      depth=$((depth - 1))
      summ "$suff"

      for attr in $(attrs_to_check "$suff" | grep -v "types.types"); do
          if [ $depth -eq 0 ]; then
              summ "$attr" | sed -e "s/^/$attr./"
          else
              deep_summ "$attr" "$depth" | sed -e "s/^/$attr./"
          fi
      done
  }

  (
      cd nixpkgs

      #git add .
      #git commit -m "Auto-commit, sorry" || true
      git checkout fixed-lib
      deep_summ > ../fixed-lib
      git checkout master
      deep_summ > ../master
  )

  if diff master fixed-lib; then
      echo "SHALLOW MATCH!"
  fi

  (
      cd nixpkgs
      git checkout fixed-lib
      repl .types

Tuomas Tynkkynen 5674da5aed Fix "treewide: Consistently call ARM 'arm'"
0c0fad6141 was broken. I didn't realize there's some hidden
metaprogramming code where one can't even grep for 'isFoo' to find its
definition :(

Elsewhere, things called GNU indeed includes GNU/Linux or GNU/Hurd, but this
predicate was defined excluding Linux regardless of userland.

Revert "Merge pull request #25275 from Ericson2314/platform-normalize"
This reverts commit 2282a5774c, reversing
changes made to 14adea9156.

The lib tests are bloking nixpkgs-unstable, and I don't like debugging
it soon enough.

John Ericson fcde869e7e lib platform parsing: Fix windows
There is no more `cygwin` OS, but instead a `cygnus` abi. "win32"
and "mingw32" parse as `windows`. Add a 3-part hack because autotools
breaks on explicit abi with windows-like (e.g. "i686-pc-windows-gnu").

Also change cross triples to conform
