    Extend ghc environment file features

    A set of changes to enable local ghc env files to be useful for tools
    like cabal. Ultimately it will allow cabal to maintain a ghc env file so
    that users can simple run ghc or ghci in a project directory and get the
    expected environment of the project.

    Change the name of .ghc.environment files to include the platform and
    ghc version, e.g. .ghc.environment.x86_64-linux-7.6.3, since their
    content is version specific. Strictly speaking this is not backwards
    compatible, but we think this feature is not widely used yet.

    "Look up" for a local env file, like the behaviour of git/darcs etc. So
    you can be anywhere within a project and get the expected environment.

    Don't look for local env files when -hide-all-packages is given.

    Extend the syntax of env files to allow specifying package dbs too.

    Test Plan:
    Currently completely untested. Compiles, that is all.
    Sorry, have to disappear for the hols.
