requires them. Disable executable bits and shebang lines in test and
benchmark files in order to prevent using a random system python, and in
source files of modules which don't provide command line interface. Fixed
shebang line to use python3 executable in the unittestgui script.
I thought I had run the full test suite before the last checkin, but
obviously I didn't. test_multibytecodec_support.py isn't really a test file,
it is a support file that contains a base test class. Rename it to
multibytecodec_support so that regrtest test discovery doesn't think it is a
test file that should be run.
