TS, TSGLEE: added error messages

TS: Created an interface to initialize the time integrator error to a specific value (for restarts)
TSGLEE: Implemented the initialization of the error/auxiliary solution

TS: Fix in TSGetTimeError and TSGetAuxSolution so that it doesn't crash for TSTypes that don't have them.

TS: created interfaces for TSGetAuxSolution, and TSGetTimeError
TSGLEE: Implemented TSGetAuxSolution, and TSGetTimeError, also TSGetSolutionComponents return all r components, not r-1

TSGLEE, TS: Renamed TSGetAuxSolution to TSGetSolutionComponents

TS, TSGLEE: created an interface for a "starting method". Set it to a default starting method for TSGLEE.

TS, TSGLEE: added interface for getting "auxiliary" solutions, which in the case of TSGLEE, is the y~ or the eps

TSGLEE: Implemented the General Linear methods with Error Estimation

TSPostEvaluate: Format doc line to conform display width.

TSPostEvaluate: Updated docs for TSSetPostEvaluate() and TSSetPostStep() to explain the differences between the two.

TSPostEvaluate: Support for setting a custom post evaluate function (Only added to TSRK for now)

TSPostEvaluate: Support for setting a custom post evaluate function (Only added to TSRK for now)

TSPostEvaluate can be used for modifying the solution after the step evaluation. Having TSPostEvaluate enables
the user to solve DAEs with PETSc's explicit methods using a partitioned approach in which the differential
variables are updated by the time-stepping solver while the algebraic variables are updated through user
callbacks in TSPostStage() and TSPostEvaluate(). Another use of TSPostEvaluate is to modify the solution such as
via some filtering. Typically such filtering operations (from Emil) are done in TSPostStep(). However, TSEvent can
modify the solution if it detects an event thus making the action taken in TSPostStep() invalid. So, instead of
doing the filtering in TSPostStep(), the users should rather do it in TSPostEvaluate().

Some Fortran stubs that returned strings could produce garbage

Some Fortran stubs that returned strings did not properly use FIXRETURNCHAR() to blank out the end of the Fortran string. Thus the Fortran string would contain "garbage".

TS: Changed TSGL to TSGLLE because TSGL is too general and we want to emphasize that TSGLLE is a type of GL with local error estimation.

Revert Barry's commit bd373395e526a8abeca18718888f591d98e14969

It broke Jed's cool support for TS TSComputeRHSJacobianConstant
Had Jed actually added his test cases to the nightly build this
breakage would have been detected immediately but instead it had to
take years to find. Why write the test cases if you are not going to
add them to be run automatically with testing?

Update the test output for changes in formatting of various XXView commands
and added the tests to be automatically run!
