    Add more fields to plan.json schema · d2f7845d

    This adds the following new fields:
    
     - `.compiler-id`
     - `.os`
     - `.arch`
     - `.install-plan[].pkg-name`
     - `.install-plan[].pkg-version`
     - `.install-plan[].pkg-src-sha256`
    
    Having separate "pkg-{name,version}" fields is desirable because the "id"-field
    is actually a UnitId which is supposed to be an opaque id which may not
    always be easily convertible into a PackageId via string operations.
    
    The "pkg-src-sha256" is generally useful to uniquely identify a
    source-tarball (when the package-id is not exact enough).
    
    Finally, the compiler-id/os/arch information is needed to determine the
    values of the respective impl()/os()/arch() predicates used in
    conditionals in .cabal files.
    
    Here's an example demonstrating the new fields:
    
        {
          "cabal-version": "1.25.0.0",
          "cabal-lib-version": "1.25.0.0",
