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.

GDB commit a207f6b3a38 ('Rewrite "python" command exception handling')
changed how exit() called from Python scripts loaded by GDB behave,
turning it into an exception instead of a generic error code that is
returned. This change caused several QEMU tests to crash with the
following exception:
Python Exception <class 'SystemExit'>: 0
Error occurred in Python: 0
This happens because in tests/guest-debug/test_gdbstub.py exit is
called after the tests have completed.
This commit fixes it by politely asking GDB to exit via gdb.execute,
passing the proper fail_count to be reported to 'make', instead of
abruptly calling exit() from the Python script.

Both the report() function as well as the initial gdbstub test sequence
are copy-pasted into ~10 files with slight modifications. This
indicates that they are indeed generic, so factor them out. While
at it, add a few newlines to make the formatting closer to PEP-8.
