PS: folks, this commit changes the interface file format, so you'll
need to do a thorough 'make clean' in libraries!!

|   Log:
|       ------------------------------------------
|       1. New try and module and package dependencies
|       2. OrigNameCache always contains final info
|       ------------------------------------------
| 
|   These things nearly complete sorting out the incremental
|   linking problem that started us off!
| 
|   1. This commit separates two kinds of information:
| 
|     (a) HscTypes.Dependencies:
|       What (i)  home-package modules, and
|            (ii) other packages
|         this module depends on, transitively.
| 
|         That is, to link the module, it should be enough
|         to link the dependent modules and packages (plus
|         any C stubs etc).
| 
|         Along with this info we record whether the dependent module
|         is (a) a boot interface or (b) an orphan module.  So in
|         fact (i) can contain non-home-package modules, namely the
|         orphan ones in other packages (sigh).
| 
|     (b) HscTypes.Usage:
|         What version of imported things were used to
|         actually compile the module.  This info is used for
|         recompilation control only.
| 
|   2. The Finder now returns a correct Module (incl package indicator)
|   first time, so we can install the absolutely final Name in the
|   OrigNameCache when we first come across an occurrence of that name,
|   even if it's only an occurrence in an unfolding in some other
interface
|   file.  This is much tidier.
| 
|   As a result Module.lhs is much cleaner
|       No DunnoYet
|       No mkVanillaModule
|   ALl very joyful stuff.
