This commit adds support for passing arguments to the GDB test scripts
so it's possible to parse the args in an "argparse way" in the test
scripts launched by the runner. The arguments should be preceded by --
when passed to the runner. For example, passing "--help" arg to the
GDB_TEST_SCRIPT:
run-test.py [...] --test <GDB_TEST_SCRIPT> -- --help
The test script should not use the argparse module directly but import
arg_parser from test_gdbstub module. arg_parser then can be used just
like the argparse.ArgumentParser class:
from test_gdbstub import arg_parser
p = arg_parser(prog="test-mytest.py", description="My test.")
p.add_argument("--vowel", help="Select vowel",
required=True, choices=['a','e','i','o','u'])
[...]
The arg_parser allows a smooth and informative exit if, for instance,
the caller of the runner script passes an invalid argument or misses a
required argument by the test script.
