Don't parse "x:x" as a URI
...
URIs now have to contain "://" or start with "channel:".

Add primop genList
...
This can be used to implement functions like ‘imap’ (or for that
matter, ‘map’) without the quadratic complexity incurred by calling
‘++’ repeatedly.

* Generalised the dependencyClosure primop to builtins.genericClosure,
...
which is hopefully more useful.
* New primops: length, mul, div.

* Export the nix-env derivation name parsing and version comparison
...
logic through the `parseDrvName' and `compareVersions' primops.
This will allow expressions to easily check whether some dependency
is a specific needed version or falls in some version range. See
tests/lang/eval-okay-versions.nix for examples.

New primitives:
...
* `sub' to subtract two numbers.
* `stringLength' to get the length of a string.
* `substring' to get a substring of a string. These should be enough
to allow most string operations to be expressed.

...
* Put common test functions in tests/lang/lib.nix.
