- Finder now copes with .hi-boot files
- some driver fixes:  the -osuf flag turns out to mean "object suffix"
  rather than "output suffix" (duh.  it makes more sense that way after
  all).

Most, but not all changes needed to get CompManager to compile.

Move readIface from RnM to IO, and commensurate changes.  Also, add a
field to ModuleLocation to hold preprocessed source locations.

Only pass a ModuleLocation into hscMain, not a ModSummary, so as to
facilitate Main.main not necessarily being in Main.hs.

Don't be so promiscuous about hoovering up any and all files into the
home/package directory caches.

First steps to making it work

fix location of .hi file for packages

wibbles

Half-way through versioning so it will compile, sans interpreter, with 4.08.1

remove unneeded exports

Track changes to the finder (now is a global variable and not passed
around).  Also some fixes to flag handling.

Don't pass the finder around any more.  Instead, its state lives in
the I/O monad.

module Finder (
    newFinder, 		-- :: PackageConfigInfo -> IO (),
    findModule,		-- :: ModuleName -> IO (Maybe (Module, ModuleLocation))
    ModuleLocation(..),
    mkHomeModuleLocn,
  ) where

fill in the package cache on the first lookup too.

Change the finder so that it doesn't fill in the home cache until it
is first used.

Compile everything up to Main.  The Really Entertaining News (tm) is that
there are still modules beyond Main to fix up :-)

Simon's stuff

Small cleanups.

Mainly renamer

Flags hacking:

   - `dopt_GlasgowExts'  is now written `dopt Opt_GlasgowExts'
   - convert all the warning options into DynFlags

add some comments

re-implement the finder using information from the driver.  The Finder
now has type

	ModuleName -> IO (Maybe (Module, ModuleLocation)

where
	data ModuleLocation  = ModuleLocation {
				hs_file  :: FilePath,
				hi_file  :: FilePath,
				obj_file :: FilePath
			      }

For a module in another package, the hs_file and obj_file components
are undefined.
