Convert MPI error type to PETSc error with string message for all MPI calls
Now PETSc examples will ONLY return PETSc error codes and never MPI error codes directly so we can understand and post-process their
errors better.
The test harness will now automatically retry tests that fail with MPI, this may help with Intel MPI that produces
seemingly random failures.

Introduce UNKNOW_NONZERO_PATTERN for MatAXPY() make it the default for TS when using both IJacobian and RHSJacobian
Provide TSSetMatStructure() to allows users to indicate the nonzero structure relationship between the RHS and I Jacobian
When the RHS Jacobian matrix is not set and is obtained with a MatDuplicate() from the I Jacobian set the flag to SAME_NONZERO_PATTERN
Add MatStructures and update SLEPc to compile with no warning message after the new MatStructure MAT_UNKNOWN_PATTERN was introduced

Support smart shifting for TSComputeRHSJacobianConstant
Since the SNES Jacobian matrices and the TS Jacobian matrices are different, we can safely shift the SNES Jacobians. The TS Jacobian is used only for generating RHS (u'=A*u).
