common: mpi helper functions

based on PCU's api

common/test: use phio stats interface

phIO: add stats interface

test: use streamio_setup_r instead of streamio_setup_write and streamio_read_r

common: create a phio_fp handle from a restart stream in read or write mode

this should replace streamio_setup_write(...)

common: support reading from restart streams

common: loop iteration limit was off by one

common: test zero sized stream write and read

build within phastaChef to run this test; core has phstream.h/cc

phSolver: update input.config with git hash when there is a commit

if the commu string is not quoted properly print a helpful message

incompressible: replace ic_serial_test macro with add_test call

common: use clean reference directory for read-only tests

compressible: append solver name to test name

incompressible: append solver name to test name

compressible: replace remaining macros

compressible: replace test macros

compressible: remove valgrind tests

incompressible: remove valgrind tests

incompressible: remove broken restart comparison

incompressible: start replacing test macros

phSolver: link against SCOREC/core/phasta for phstream

new compressible test case

add a for loop to support multiple tests

before pushing up to github a little more description of the Shock Adaptivity changes

moved shock-capturing error so that it works when DC is off
