  1. modules: add mydef_boot 

    MyDef provides general templating facilities.

  2. test/mpi: add p2p benchmarks in test/mpi/bench 

    Add point-to-point benchmark code in MyDef. The tests have automatic
warm-ups and adjusts number of iterations for measurement accuracy.
It produces latency measurements with standard deviations and equivalent
bandwidths.

MYDEF_BOOT=[topsrc_dir]/modules/mydef_boot
export PATH=$MYDEF_BOOT/bin:$PATH
export PERL5LIB=$MYDEF_BOOT/lib/perl5
export MYDEFLIB=$MYDEF_BOOT/lib/MyDef

To run:
    mydef_page p2p_latency.def  # -> p2p_latency.c
    mpicc p2p_latency.c && mpi_run -n 2 ./a.out

Alternatively use mydef_run (uses settings from config):
    mydef_run p2p_latency.def

Next commit will add "make testing".

  3. autogen: convert mydef code in autogen 

    We could add rules to directly work with mydef code in Makefile, but
convert the code in autogen removes the mydef dependency.

Also fix a spelling error.

  4. test/runtests: add TestBench result check 

    This check does not capture output (thus test results will show in
console log) and only checks for exit code - zero means success and
nonzero means failure.

We'll use this check for benchmark tests.

  5. test/bench: add Makefile and testlist 

    "make testing" in test/mpi/bench should work.

  6. test/bench: add support for device memory 

    Add device memory support using mtest_common utilities. This will add
the dependency to utility libraries, which the makefile already
imports.

However, this will remove the simpliicity of building single
source with mpicc or mydef_run. If one doesn't need test device memory,
one can simply comment off "$include macros/mtest.def" to restore the
simplicity.
