Keep pgm paths in native format

Import wibbles

Fix so that it compiles on both pre and post 5.00 series compilers.

Remove hacked-in definition of system for mingwin; instead we now just link
against the new version of systemCmd from lib/std/cbits/system.c.

Instead of using the old kludgedSystem on Windows, use the new system. This
makes the use of DOS built-ins such as copy work, which they didn't when the
command was run under sh (as the old kludgedSystem did).

Make it compile

More windows wibbles

* Restore SysTools.system, which implements a kludged version
  of system for reasons that are explained at length in the comments
  [overlong command-lines fail if compiling GHC with pre-5.02 GHCs]

* Wibble in Makefile

- separate location installed binaries from non-binaries (previously
  installed package.conf was in $(libdir)/extra-bin).

- remove v_Path_Perl so that we don't accidentally wire-in the location of
  perl on Unix systems.  It wasn't actually used anywhere.

- minor non-functional cleanups and comment fixups.

- We still look for package.conf twice; I haven't done anything about
  this yet.

Some tidying up

* Remove CmStaticInfo
   - GhciMode moves to HscTypes
   - The package stuff moves to new module main/Packages.lhs

[put any package-related stuff in the new module]

* Add Outputable.docToSDoc

Add getExecDir to return current directory of executable on Windows (to find
config information).

Windows wibbles

----------------------
	Installation packaging
	----------------------

GHC runs various system programs like
	cp, touch
	gcc, as, ld etc

On Windows we plan to deliver these programs along with GHC,
so we have to be careful about where to find them.

This commit isolates all these dependencies in a single module

	main/SysTools.lhs

Most of the #ifdefery for mingw has moved into this module.
There's some documentation in SysTools.lhs

Along the way I did lots of other cleanups.  In particular

  * There is no more 'globbing' needed when calling runSomething
  * All file removal goes via the standard Directory.removeFile
  * TmpFiles.hs has gone; absorbed into SysTools
  * Some DynFlag stuff has moved from DriverFlags to CmdLineOpts


Still to do:

  **	I'm a bit concerned that calling removeFile one at a time
	when deleting masses of split-object files is going to be
	rather slow

  **	GHC now expects to find split,mangle,unlit in
		libdir/extra-bin
	instead of just
		libdir

	So something needs to change in the Unix installation scripts

  **    The "ineffective C preprocessor" is a perversion and should die
