Further work on tests path change.
Finished changes for test dir paths.
Disabled remaining tests..
Adding stdlib.h to file_parser.c
Fixing TEST_FILE_DIR path.
Fixing some node comparisons in the C++ bindings.
Switched the order of TEST_FILE_DIR and VALGRIND_ENVIRONMENT in order for TEST_FILE_DIR to be visible in valgrind builds. Cleaned up the code for file path resolution in file_parser.cpp
Moved file path code dealing with getenv(TEST_FILE_DIR) to the google test code instead of having it in our general C++ public api. Refactored the loadVtt functions to normalize them a bit.
