Before the change, the common Emacs test scheme was to print buffer content to stdout and redirect it to a file or capture it in a shell variable. This does not work if we switch to using emacsclient(1) for running the tests, because you can not print to the stdout in this case. (Actually, you can print to stdout from Emacs server, but you can not capture the output on emacsclient(1)). The patch introduces new Emacs test auxiliary functions: `test-output' and `test-visible-output'. These functions are used to save buffer content to a file directly from Emacs. For most tests the changes are trivial, because Emacs stdout output was redirected to a file anyway. But some tests captured the output in a shell variable and compare it with the expected output using test_expect_equal. These tests are changed to use files and test_expect_equal_file instead. Note: even if we do not switch Emacs tests to emacsclient(1), the patch makes tests cleaner and is an improvement.
