Merge pull request #795 from RosettaCommons/jadolfbr/mpi_dbout
This merge fixes 2 FeaturesReporter MPI Issues:
Bugs Fixed
---------------
1) Allows the use of the command-line flag for separate_db_per_mpi_process to work in with the XML.
2) Fixes a nasty bug that was sending the MPI JOB_FAILURE_TAG instead of the REQUEST_MESSAGE_TAG when requesting batch and protocol ids for MPI. This fixes sqlite3 MPI and may fix MySQL MPI if it was broken as well.
Code and Test
-------------------
Reorganized basic/message_passing into basic/mpi and moved enums out of MPIJD and into this namespace. This allows use of the enums instead of ints, which should help prevent something like this in the future (Thanks Vikram!)
Add MPI integration test for this (Again, thanks Vikram!).
Expected Test Failures
-------
Some cosmetic changes in integration tests that used the message_passing namespace. MPI integration test will fail for being new.
