Parrot Based Config

Discussion about the Roadmap item for 3.0

Things that should be changed, regardless of the tools used to implement the configure system.

• Should be able to override hints files from the command line. Let the user shoot themselves in the foot.
• Don't run configure tests as part of 'make test' - if the parrot tests pass, Configure worked.
• use a standard mechanism for parsing options, to unify the true/false/set/unset/use/don't syntax.
• Don't rely on perl's Config for information.
