python-gdb.py now handles errors on computing the line number of a Python frame. Changes: * PyFrameObjectPtr.current_line_num() now catchs any Exception on calling addr2line(), instead of failing with a surprising "<class 'TypeError'> 'FakeRepr' object is not subscriptable" error. * All callers of current_line_num() now handle current_line_num() returning None. * PyFrameObjectPtr.current_line() now also catchs IndexError on getting a line from the Python source file. (cherry picked from commit 2e438cc)
