Eelco Dolstra bf010ace55 * Remove the mysterious `_args' attribute because it screws up the
manual generation (causes `nixos-rebuild build-vm' evaluation to
  fail in the `networking.ifaces' option).

Eelco Dolstra 1ba3165b4e * Allow the default for option values displayed in the manual to be
overriden.  Some defaults should not be evaluated because they cause
  unnecessary evaluation or might cause evaluation errors
  (e.g. assertions).  For instance, the value of the
  `boot.kernelPackages' option is an attribute set.  Some packages in
  that set might not evaluate (e.g. AUFS2 on kernels that don't have
  the AUFS2 patch), and in any case it slows down nixos-rebuild to
  evaluate lots of packages that are not actually used in the
  configuration.

Eelco Dolstra 9ec34da2ee * In the generation of the `options.xml' file used to produce the
NixOS manual and  manpages, remove all derivation attributes except
  the `name' attribute.  This cuts the size of `options.xml' from 7.0
  MiB to 473 KiB, and more importantly, cuts evaluation time of the
  system derivation from 1.63s to 1.10s on my laptop (a 32%
  improvement).

Nicolas Pierron bbb4ce1dd7 Extract the path done inside the iteration process of the option type and
give it as argument to each sub-module.

Nicolas Pierron 33d43ac18b Add extraConfigs attribute inside options. This attribute is used to
insert definitions from an external location.  As opposed to other
defintions, these definitions are always embedded into a list which allow
to add multiple definitions with one module.

!!! This feature _should not_ be used as a new mean to define options.

Nicolas Pierron 0c16b00cbd Replace the traversal of modules:
- Remove handleOptionSets which used option declarations & definitions
in the same set.
- Add a traversal of modules where "config" and "options" are traverse at
the same time.

This allow to have accruate error messages with the incriminated files
playing a role in the error.

This system add a new restriction compare to the previous system:
- A module with no structure (option definitions & option declarations
& require) should not contain any option declarations.  If such module
exists you must convert it to the following form:

{ imports = <content of the require attribute>;
  options = <set of option declarations>;
  config = <set of option definitions>;
}

Eelco Dolstra 599015e8b0 * Split lib/default.nix into several files, as it had become a big
mess.  Also cleaned up some functions:

  - foldl appeared broken (it recursively called fold).
  - Renamed logicalAND/logicalOR to and/or.
  - Removed listOfListsToAttrs, eqStrings: obsolete.
  - Removed isInList, which does the same thing as elem.
  - stringToCharacters: don't return a "" at the end of the list.
  - Renamed concatList to concat, as concatList (singular) is a
    misnomer: it takes two lists.  Likewise, renamed mergeAttr to
    mergeAttrs.

  misc.nix still contains a lot of stuff that should be refactored and
  moved to other files.

Eelco Dolstra d897fc5501 * Some prototype code to make dealing with options in Nixpkgs/NixOS
easier.  Instead of writing

    config.get ["foo" "bar"]

  it would be much cleaner to just write

    config.foo.bar

  only this doesn't handle the case where option foo.bar is not
  supplied in the configuration; in that case we need to take the
  default value from some set of option definitions
  (system/options.nix in NixOS).

  Following a suggestion from Martin, the function `combine' (need
  better name) takes a set of option definitions (which follow the
  attribute set structure of the options) and a set of options and
  fills in missing values in the latter with default values from the
  former.  This only works with very recent versions of Nix (it needs
  Marc Weber's listToAttrs primop).
