5558652709 Don't substitute derivations that have preferLocalBuild set 
In particular this means that "trivial" derivations such as writeText
are not substituted, reducing the number of GET requests to the binary
cache by about 200 on a typical NixOS configuration.

2754a07ead nix-store -q --roots: Respect the gc-keep-outputs/gc-keep-derivations settings 
So if a path is not garbage solely because it's reachable from a root
due to the gc-keep-outputs or gc-keep-derivations settings, ‘nix-store
-q --roots’ now shows that root.

93227ff65c * Eliminate all uses of the global variable ‘store’ from libstore. 
This should also fix:

    nix-instantiate: ./../boost/shared_ptr.hpp:254: T* boost::shared_ptr<T>::operator->() const [with T = nix::StoreAPI]: Assertion `px != 0' failed.

  which was caused by hashDerivationModulo() calling the ‘store’
  object (during store upgrades) before openStore() assigned it.

bdf089f463 * Before a build, show the disk space that the downloaded store paths 
will approximately require.

fdcaf37361 * Made `nix-store -qR --include-outputs' much faster if there are 
multiple paths specified on the command line (from O(n * m) to O(n +
  m), where n is the number of arguments and m is the size of the
  closure).

03427e76f1 * querySubstitutablePathInfo: work properly when run via the daemon. 
* --dry-run: print the paths that we don't know how to build/substitute.

* Optimise header file usage a bit.
* Compile the parser as C++.

c8bfb11b34 * `nix-env (-i|-u) --dry-run' now shows exactly which missing paths 
will be built or substituted.
