Added parSafe=false to a test
Add parallel execution of make to lots of testing scripts.
Do not use parallel execution when calling `make check`.

start_test breaks because the backend C build (inside chpl compiler) calls
make. However, when that make starts up, it assumes it is a submake and
attempts to communicate with a job server that does not exist. There is
probably some way to fix that (one thought is to set .NOTPARALLEL in the
Makefile.exe), but it is simple enough to call regular make with parallel
execution and then make a second call to make check.
An initial version of jacobi-unroll.  Need to ask Ian and Cathie
about the fact that it still doesn't pass the correctness test.

Improve error handling in nightly when CHPL_NIGHTLY_LOGDIR is not set.

* Report error and exit with non-zero code if CHPL_NIGHTLY_LOGDIR is not set
  (or empty) in -cron mode.
* Try to create the logdir, if it does not exist already (for both -cron and
  -debug modes).
* Check that directory is accessible in both -cron and -debug modes.

Some of these things were already done in -debug mode.

I am adding the baseline c version of the code
Including 2 different version of the the CFD-mini benchmark.
One is the baseline chapel

Adding jacobi-unroll example to colostate study.
Last week I had started reworking my noinit tests now that _defaultOf is in the
repository.  This is just storing all those changes until I can get back to it
Merge remote-tracking branch 'upstream/master'
Number of edits:
1) re-renamed the 1D/2D situation.
   Names reflect the data dimensionality, and not the dimensionality of the tile.
2) Unified graphs by dimension. There is now only a Jacobi-1D and Jacobi-2D graphs.
Remove self comparisons in test/extern/ferguson/c_ptrs.chpl

c_ptrs.chpl had comparisons that looked like:

assert(my_ptr == my_ptr);

These now check that my_ptr != c_nil. I added a couple of overloads in
SysBasic to allow comparison between c_ptr and c_void_ptr to let us do
this.
Snapshot -- got 3D working, but broke 1D
This version works for 1D and 3D again
Let a script override testEnv in sub_test &c.
