[issue12231] regrtest: add -k and -K options to filter tests by function/file names

[STINNER Victor]

New submission from STINNER Victor <victor.stinner at haypocalc.com>:

Attached patch adds -k/--func-regex and -K/--file-regex options to filter tests by function/file names. It modifies makeSuite() and getTestCaseNames() functions of unittest.loader to add an optional filter argument: callback taking a function name as argument and returning False if the test should be ignored. You can use the new options more than once and their argument are regular expressions (case insensitive).

Examples:

- "./python -m test -k subprocess -K pass_fds" runs only 1 function of 1 file: test_subprocess.test_pass_fds()
- "./python -m test -k os$" runs 1 file: test_os
- "./python -m test -K codecencoding" runs 6 files: test_codecencodings_cn, test_codecencodings_hk, test_codecencodings_iso2022, test_codecencodings_jp, test_codecencodings_kr, test_codecencodings_tw
