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.

Merge branch 'pr1819/jkruzik/feature-pcdeflation/master' [PR #1819]
* pr1819/jkruzik/feature-pcdeflation/master:
PCDeflation.
Implements multilevel deflation preconditioner that can shift part of the spectrum to a predefined value.
Given a full rank deflation matrix W, the deflation preconditioner uses projections Q = W*(W'*A*W)^{-1}*W' and P = I - Q*A.
It computes computes initial guess x0 = x_{-1} - Q*r_{-1} which is the solution on the deflation space.
The preconditioner application consists of P*M^{-1} + factor*Q, where M^{-1} is an additional preconditioner.
See the documentation for PCDEFLATION above PCCreate_Deflation for more detailed description.
