Shamrock Lee 60950f739e lib/meta: add getLicenseFromSpdxId function
Move function spdxLicense, internally used in yarn2nix
to lib/meta.nix, and
rename to getLicenseFromSpdxId

A similar function is implemented in poetry2nix,
but the one originally in yarn2nix seems beter.
since it falls back to an license-like attrset
for mismatched case
instead of a plain string

kexectools: Disable only on RISC-V if Linux.
The isKexecable flag treated Linux without kexec as just a normal
variant, when it really should be treated as a special case incurring
complexity debt to support.

John Ericson e547bd0dc4 lib: Factor in tiny bit of meta.platform checking
I need it in stdenv and release-lib, so that seems motivation enough.

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
  )

Aneesh Agrawal bd9246b009 treewide: Always use integers for meta.priority
Meta attributes types are now enforce as of commit
90b9719f4f,
so ensure meta.priority is always set to an integer.

This fixes evaluation of `linuxPackages_latest.virtualbox`
(the impetus for this commit)
and other packages that use lowPrio or hiPrio.

Eelco Dolstra e167cf9f21 Make appendToName do the right thing
I.e. append a suffix *before* the version, rather than after.  So we
get "sqlite-interactive-3.8.0.2" instead of
"sqlite-3.8.0.2-interactive".  The latter is broken since nix-env just
sees it the suffix as part of the version, so "nix-env -u" will
happily upgrade "sqlite-3.8.0.2-interactive" to "sqlite-3.9".

Eelco Dolstra 8890492872 openjdk: Ugly hack to fix nix-env installation
Nix-env always wants to install all outputs of a derivation, but this
failed for openjdk/openjre because openjdk has some symlinks (such as
bin/java) to openjre.  Also, it prevents installing the openjre
without the openjdk.  So as a workaround, mess with the "outputs"
attribute to fool nix-env.

Also, give openjre a separate name and description.

Fixes #1535.
