    Generalize exposed-modules field in installed package database
    
    Summary:
    Instead of recording exposed-modules and reexported-modules as seperate
    fields in the installed package database, this commit merges them into
    a single field (exposed-modules).  The motivation for this change is
    in preparation for the inclusion of *signatures* into the installed
    package database, which may also be reexported.  Merging the representation
    means that we can treat reexports uniformly, no matter if they're a normal
    module or a signature.
    
    This commit adds a stub for signatures, but that code isn't wired up to
    anything yet.
    
    Contains Cabal submodule update to accommodate these changes.
