Bug 1411462 - Add test for `configure --help`; r=glandium We add a simple cram test that `configure --help` works. I added the test to build/tests because I'm not sure where else it should go. This test uncovers a few interesting things: 1) piping `./configure --help` to `head` directly causes a Python traceback (presumably due to the pipe disappearing once N lines have been read) 2) "checking for vcs source checkout" is printed for --help 3) It is printed twice (!!) These will be addressed later. Establishing test coverage is more important. MozReview-Commit-ID: 9zQ5X8ulTkc --HG-- extra : rebase_source : aaf660152cdfe37580f559976bca13ea9bf14c49

Bug 1411462 - Abort when I/O error seen; r=glandium Before, I/O errors writing to stdout/stderr (e.g. due to broken pipe) would result in handleError() being called and execution would keep running. This would potentially result in an error message for every log/line failure being printed to stderr. We change the behavior so I/O failures are fatal and abort execution. We test the new behavior by changing a test to pipe to `head` directly. Since `head` exits once it has seen sufficient output, this results in an EPIPE which now results in immediate program termination.
