Message Logging and Inline Recovery

[Matthew-Whitlock]

Depends on the mpi_coroutines branch. See examples/08_inline_recovery/stencil.cpp for an example using message logging and inline recovery.

TODO:

• Proper integration into Fenix. Something like Fenix_Mlog_create(int log_id, MPI_Comm comm), etc.
• Support collectives. Collective consistency checking already exists, it just needs a bit more to actually log and replay the collectives. Lots of future work here, but for now just do basic support for barriers and reductions/allreductions/bcasts
• Switch to forming consistency only during the actual reset_consistency call as a blocking operation. It still needs the async mpi_coroutines stuff, but do a barrier after forming all consistency so we don't have to IProbe for every application MPI operation. It also just simplifies the logic.
• Separate the MPI override functions as a different library module that can be linked with CMake, so applications can enable/disable based on if they are using message logging.
