I've made some improvements to System.Process that I'd like to get
feedback on. Everything so far is backwards compatible in the sense
that I've only added to the API - everything that was there before is
still available, with the same semantics (except where bugs have been
fixed).

* 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
