Convert TriBITS to lower-case CMake command, macro, and function names (#274)

[bartlettroscoe]

This PR adds a new tool tribits/python_utils/lower_case_cmake.py and driver tribits/refactoring/lower-case-cmake-tree.sh that I ran on all of TriBITS (which completes #274). I had to fix several things to get the TriBITS test suite to pass after this but this looks pretty good.

I tested this locally with the TriBITS test suite and I am also testing this locally against Trilinos using the ATDM Trilinos 'sems-rhel7' configuration with 'gnu-shared-dbg'. (There is some code that got broken that is not tested in TriBITS!)

I tested this with Trilinos with an ATDM Trilinos 'sems-rhel7' configuration on my machine 'crf450' and it built and gave test results:

$ grep -A 100 "failed out of" ctest.out 
99% tests passed, 1 tests failed out of 1997

Errors while running CTest

(NOTE: This is using the flaky gather method for the build-stats wrapper that will be fixed by Trilinos PR trilinos/Trilinos#8638. This failure is unrelated to this issue.)
