gdb/testsuite/
	* lib/gdb.exp (python_supported, gdb_py_test_silent_cmd,
	gdb_py_test_multiple): New functions.
	* gdb.python/python-cmd.exp: Use Python test functions from
	lib/gdb.exp instead of defining its own functions.
	* gdb.python/python-frame.exp: Likewise.
	* gdb.python/python-function.exp: Likewise.
	* gdb.python/python-value.exp: Likewise.
	* gdb.python/python.exp: Likewise.
