[splinecommon_] Wrong index variable and other fixes

See merge request !2897

Otherwise the reverse feature would not work.
This bug exists since the beginning of splinecommon_.

Thanks Timo for spotting a mistake I'd introduced.

added updateDirichletConstraints to NoPrimaryVariableSwitch stub

See merge request !2896

fix RichardsVelocityOutput

Closes #1087

See merge request !2884

Roman Winter authored 3 years ago and Timo Koch committed 3 years ago

Richards works conceptually with numPhases == 2 but only one velocity
should be computed. Therefore we need to overload the velocity output.

[md][ff-pm] Add freeflow porous medium coupling managers and test

See merge request !2826

Provide new interface subApply that applies a given function to
the correct sub coupling manager making available the correct local indices.

Also makes problem interfaces obsolete which is fixed in the same commit
for the freeflow-darcy stuff (the only coupl manager using the binary model so far)

with fixes of coupling context by Timo
- updateCouplingContext was never called due to some overload issue
- fixed the function to actually update the coupling context
- be careful with obtaining element from stored geometry, the element
  pointer might be dangling!
