Modify TSSetPreStep and TSSetPostStep to run every step rather than once per call to TSStep.

It was not useful to place these at the start and end of the entire
time-stepping sequence (because the user might as well have called their
functions directly). With these hooks, it is at least possible for the
user to implement IMEX schemes within TS.

Implicit formulation in TS, TS_THETA

TS: Adding support for implicit form F(t,X,Xdot)=0, suitable for DAE

TS_Theta: Implementation of theta integrator cast as a 1-stage
Runge-Kutta method which uses the implicit form and thus may be applied
to DAE.

TS: Cleanup unused/broken TS methods.

- the methods TS::reform(), TS::reallocate() were neither set nor called
ever.
- TS::update() and TS::postupdate() could be set, however update() would
never be called, and postupdate() only in one place, for sundials.
This functionality will be taken over by prestep() / poststep()
eventually.
