This reverts commit a41fd3b.

* Travis fixes (sandialabs#55)

Fix some travis/testing issues.

Travis now pulls from ULFM master branch when it needs to rebuild ULFM.
Travis has an environment variable enabling oversubscription during the tests, instead of having that on all platforms when running make test
Tests that involve failure have their timeouts individually set to 1, so tests don't take 10+ seconds each w/ the default timeout of 10s
Simplified travis scripts (no more .travis_helpers directory)

Fix some travis/testing issues.

Travis now pulls from ULFM master branch when it needs to rebuild ULFM.
Travis has an environment variable enabling oversubscription during the tests, instead of having that on all platforms when running make test
Tests that involve failure have their timeouts individually set to 1, so tests don't take 10+ seconds each w/ the default timeout of 10s
Simplified travis scripts (no more .travis_helpers directory)

* First pass at removing the request store

New function, "Fenix_test_cancelled" for checking if pre-failure requests completed or were cancelled.

One thing to try finding a solution for: If a failure was found during an MPI_Test, that request has
already been removed from MPI internals and replaced w/ MPI_REQUEST_NULL. Fenix_test_cancelled will
report that this req was completed

* Implement custom errhandler

This includes removing the option for comm_replace - users now must provide
a comm pointer to fenix_init and cannot rely on fenix to automatically replace
their input comm with the resilient comm.

* Fenix comms are stack-allocated now, instead of malloced

* Cleanup redundant set_errhandler calls

* Fix data recovery bug

* Add usage instructions to all examples/tests

* Add support for MPI_Issend and MPI_Ssend (#3)

Merge in Issend test
