    Support for abi-depends for computing shadowing. · ee4e1654
    Edward Z. Yang authored
    This is a complete fix based off of
    ed7af26606b3a605a4511065ca1a43b1c0f3b51d for handling
    shadowing and out-of-order -package-db flags simultaneously.
    The general strategy is we first put all databases together,
    overriding packages as necessary.  Once this is done, we successfully
    prune out broken packages, including packages which depend on a package
    whose ABI differs from the ABI we need.
    Our check gracefully degrades in the absence of abi-depends, as
    we only check deps which are recorded in abi-depends.
    Contains time and Cabal submodule update.
