Add new methods to the PendingFrame and Frame classes to obtain the stack frame level for each object. The use of 'level' as the method name is consistent with the existing attribute RecordFunctionSegment.level (though this is an attribute rather than a method). For Frame/PendingFrame I went with methods as these classes currently only use methods, including for simple data like architecture, so I want to be consistent with this interface. gdb/ChangeLog: * NEWS: Mention the two new methods. * python/py-frame.c (frapy_level): New function. (frame_object_methods): Register 'level' method. * python/py-unwind.c (pending_framepy_level): New function. (pending_frame_object_methods): Register 'level' method. gdb/doc/ChangeLog: * python.texi (Unwinding Frames in Python): Mention PendingFrame.level. (Frames In Python): Mention Frame.level. gdb/testsuite/ChangeLog: * gdb.python/py-frame.exp: Add Frame.level tests. * gdb.python/py-pending-frame-level.c: New file. * gdb.python/py-pending-frame-level.exp: New file. * gdb.python/py-pending-frame-level.py: New file.
