* Split test_pycfunction.py: add test_cfunction_full.py. Split the function into the following 6 functions. In verbose mode, these "pycfunction" tests now log each tested call. * test_pycfunction_noargs() * test_pycfunction_o() * test_pycfunction_varargs() * test_pycfunction_varargs_keywords() * test_pycfunction_fastcall() * test_pycfunction_fastcall_keywords() * Move get_gdb_repr() to PrettyPrintTests. * Replace DebuggerTests.get_sample_script() with SAMPLE_SCRIPT. * Rename checkout_hook_path to CHECKOUT_HOOK_PATH. * Rename gdb_version to GDB_VERSION_TEXT. * Replace (gdb_major_version, gdb_minor_version) with GDB_VERSION. * run_gdb() uses "backslashreplace" error handler instead of "replace". * Add check_gdb() function to util.py. * Enhance support.check_cflags_pgo(): check also for sysconfig PGO_PROF_USE_FLAG (if available) in compiler flags. * Move some SkipTest checks to test_gdb/__init__.py. * Elaborate why gdb cannot be tested on Windows: gdb doesn't support PDB debug symbol files.
