Overhaul System.Process

Overhaul of System.Process

From the patch:

Tue Apr 22 15:02:16 PDT 2008  Simon Marlow <simonmarhaskell@gmail.com>
  * Overhall System.Process
     
   - fix #1780: pipes created by runInteractiveProcess are set
     close-on-exec by default
   
   - add a new, more general, form of process creation: createProcess
     Each of stdin, stdout and stderr may individually be taken
     from existing Handles or attached to new pipes.  Also it
     has a nicer API.
   
   - add readProcess from Don Stewart's newpopen package.  This
     function behaves like C's popen().
  
   - Move System.Cmd.{system,rawSystem} into System.Process.  Later
     we can depecate System.Cmd.
   
   - Don't use O_NONBLOCK for pipes, as it can confuse the process
     attached to the pipe (requires a fix to GHC.Handle in the base
     package).
  
   - move the tests from the GHC testsuite into the package itself,
     and add a couple more
  
   - bump the version to 2.0

Haddock for the new API is here: http://darcs.haskell.org/~simonmar/process/System-Process.html

Patch is attached. So far I've only modified the Unix parts of the code, the Windows parts still need to be updated.

Discussion period: 4 weeks (20 May)
