method, properties evaluated at the evaluation time are still on the values
which makes this interresting to use in conjunction with extraConfigs.
The extraConfigs values are merged with the other values and then the
properties gets evaluated.
Thus, we can keep properties like mkOverride with this method.

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.

builtin to force the evaluation of the configuration value. Thus the

moduleMerge because we may need to alter the result of the configuration
before using it inside other options.

- 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>;
}

other files.
Imports of imported attribute set are not working anymore because this
feature is hard to maintain and because this a potential source of error.
Imports are only accepted inside named modules where the system has some
control over mutual inclusion.

* unifyModuleSyntax: handle all kind of module syntax to convert them into
a module which has the following form:
{
imports = [ <paths> ];
options = <attribute set of options declarations>;
config = <attribute set (with properties) of option definitions>;
}
This function assume that there is at most one imported attribute set which
correspond to option declarations.
* moduleClosure: handle a list of module's paths which are converted with
the previous function to do the closure of the imports with the function
lazyGenericClosure (which does the same as builtins.genericClosure except
that it doesn't evaluate the content of modules). The "key" and "paths"
attributes are left to be used as debug information in futur
implementation(s).

The rationale is that usually applications don't care about the kernel
but rather about the C library, tool chain, and standard utilities,
which are GNU, not Linux.

- capable to handle the proposal of Eelco Dolstra { imports= [..]; options = {}; config = {}; } in addition to the current { require = [..]; .. } syntax.

- Do not eval properties on option declarations.

Use the option name computed by "handleOptionSets" instead of
computing it a second time. Handle option containing option sets.

Remove attribute set comparison. Imported attribute sets
are traverse assuming that no duplicate could exists.

in the Nix expression evaluator (namely that comparison of attribute
sets works properly).
* Removed some redundant parentheses in builder-defs.
svn path=/nixpkgs/trunk/; revision=15551
* Added a function mapAttrsRecursive, which is like mapAttrs, but
recursively applies itself to attribute sets.
* Commented and cleaned up some functions.

applyAndFun has a bug resulting in the same arg beeing added more than
once when using a concatenating merge function for the attr set.
I've tried giving the function a name "overridableDelayableArgs" which
resembles its usage much more.
important refactoring:
applyAndFun had .fun and .funMerge only when passing the merge
function lib.mergeOrApply
composableDerivation {
initial = {
...
};
}
to
overridableDelayableArgs has always .replace and .merge
composableDerivation {} {
...
}

Properties can be delay on any attribute set and have
functions which are used to define the semantic of each
property.

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.
