6eaae0a589 Wrap predicate functions in a newtype & separate ty params 
Also adds a Functor and Profunctor instance for predicates.  The old
predicate type is kept as an alias for the (common) case where both
tyvars are the same.

45256193c0 Implement bound threads 
This also adds forkOS(N) and isCurrentThreadBound to MonadConc, a
breaking change.

Note: forkOSWithUnmask(N) is NOT added to MonadConc, as it isn't
supported in base-4.8 (GHC 7.10).  See #132 for the action on this.

A bound thread under test gets a dedicated worker thread, which is
forked bound using the underlying MonadConc.  This worker is used for
all lifted actions, with execution as normal otherwise.

31d29c11ea Require a 'MonadConc n' instance to run 'ConcT r n' expressions 
This is preparation for adding bound threads.  The instance isn't used
in this commit, but the diff is large enough that I feel this should
be a separate commit for ease of review.

Fallout:

- The MonadBaseControl IO instance is gone, as I'm not sure how to do
  it generally.
- The pure/IO split is gone, everything is now monadic.
- The execution, SCT, and dejafu functions are of the form (MonadConc
  n, MonadRef r n) => ...
