Eelco Dolstra 6baa2c4420 * Get rid of identifiers since they are redundant now. This greatly
simplifies stuff.

* The format of Nix expressions and the database schema changed
  because of this, so it's best to delete old Nix installations.

Eelco Dolstra 5d4171f7fb * Synchronise terminology with the ICSE paper (e.g., slice -> closure,
fstate -> Nix expression).
* Fix src/test.cc.

Eelco Dolstra 2de8504791 * Delete the temporary directories of failed builds by default, and an
option `--keep-failed' to override this behaviour.

Eelco Dolstra 8846465934 * Get garbage collection and cache population to work *properly*.
Renamed `fstateRefs' to `fstateRequisites'.  The semantics of this
  function is that it returns a list of all paths necessary to realise
  a given expression.  For a derive expression, this is the union of
  requisites of the inputs; for a slice expression, it is the path of
  each element in the slice.  Also included are the paths of the
  expressions themselves.  Optionally, one can also include the
  requisites of successor expressions (to recycle intermediate
  results).

* `nix-switch' now distinguishes between an expression and its normal
  form.  Usually, only the normal form is registered as a root of the
  garbage collector.  With the `--source-root' flag, it will also
  register the original expression as a root.

* `nix-collect-garbage' now has a flag `--keep-successors' which
  causes successors not to be included in the list of garbage paths.

* `nix-collect-garbage' now has a flag `--invert' which will print all
  paths that should *not* be garbage collected.

Eelco Dolstra 949c4fa1a8 * `nix --help'.
* `nix --query --graph' to print a dot dependency graph of derive
  expressions.
