First release candidate for MCT 2.10 release

Update how buffers are allocated in Rearranger for

Merge branch 'jedwards/impi_fix' (PR #56)

Was having problems with extremely long start up times using impi on large task counts
(10,000 to 100,000.) In the process of debugging found that adding a barrier and avoiding
an unnecessary allocation on non-root tasks improves the startup performance greatly
(down from 2 or more hours to 5 minutes or less). Don't have a good explination for
this at this time, but it should be harmless.
