Change event indicator functions from PetscScalar to PetscReal. Change the API of TSSetEventHandler(): in the user `indicator()` callback, the 'fvalue' argument type changed from PetscScalar[] to PetscReal[]. Add TSSetPostEventStep(), deprecate TSSetPostEventIntervalStep(). Deprecate option -ts_event_post_eventinterval_step. Fix bugs in interaction of TSEvent with tspan. Add six new test examples. Below are the examples of bugs fixed by this patch. The source codes (ex3.c, ex3span.c, ex4.c, ex5.c) can be found in src/ts/event/tests. To run them with the older Petsc versions, one would need to comment out "#define NEW_VERSION".
