* Fix blackholing. If evaluation fails due to an assertion failure,
...
then the blackhole has to be removed to ensure that repeated
evaluation of the same value gives an assertion failure again rather
than an "infinite recursion" error.

* In eval(), don't use the target value `v' as a temporary.
...
Overwriting `v' breaks when the expression evaluation to an
assertion failure or throw.

* Quick hack to make coerceToString work more or less correctly on
...
nested lists. `nix-instantiate' can now evaluate the NixOS system
derivation attribute correctly (in 2.1s on my laptop vs. 6.2s for
the trunk).

* Make `derivation' lazy again for performance. It also turns out
...
that there are some places in Nixpkgs (php_configurable /
composableDerivation, it seems) that call `derivation' with
incorrect arguments (namely, the `name' attribute missing) but get
away with it because of laziness.

* Fixed the trace primop and path comparison.
...
* Removed exprToString and stringToExpr because there is no ATerm
representation to work on anymore (and exposing the internals of the
evaluator like this is not a good idea anyway).

* Handle string contexts. `nix-instantiate' can now correctly compute

the `firefoxWrapper' attribute in Nixpkgs, and it's about 3 times
faster than the trunk :-)

* Quick and dirty implementation of with'. with e1; e2' is

basically desugared to `let <with> = e1; e2', and `lookupVar' looks

* Simplify @-patterns: only {attrs}@name' or name@{attrs}' are now
...
allowed. So `name1@name2', `{attrs1}@{attrs2}' and so on are now no
longer legal. This is no big loss because they were not useful
anyway.
This also changes the output of builtins.toXML for @-patterns
slightly.
