Googletest death tests, MPI and fork()

D-01131

Googletest implements death tests with fork(), but child processes using MPI functions (e.g. MPI_Finalize at exit!) is undefined behaviour.

PreDev Notes:

The death tests are still being run for the moment, but are run together, separately from the rest of the tests (i.e. on 1 process, and on several processes with MPI.

An option might be to get a list of death tests and run each one individually... ? A better option would be to have ExSeisDat not crash on error, replacing death tests with catching an exception.
