Brett Cannon 9fa812668f Issue #18018: Raise an ImportError if a relative import is attempted

Brett Cannon 849113af6b Issue #25791: Warn when __package__ != __spec__.parent.
In a previous change, __spec__.parent was prioritized over
__package__. That is a backwards-compatibility break, but we do
eventually want __spec__ to be the ground truth for module details. So
this change reverts the change in semantics and instead raises an
ImportWarning when __package__ != __spec__.parent to give people time
to adjust to using spec objects.

Victor Stinner f3914eb16d co_lnotab supports negative line number delta
Issue #26107: The format of the co_lnotab attribute of code objects changes to

Changes:

* assemble_lnotab(): if line number delta is less than -128 or greater than
  127, emit multiple (offset_delta, lineno_delta) in co_lnotab
* update functions decoding co_lnotab to use signed 8-bit integers

  - dis.findlinestarts()
  - PyCode_Addr2Line()
  - _PyCode_CheckLineNumber()
  - frame_setlineno()

* update lnotab_notes.txt
* increase importlib MAGIC_NUMBER to 3361
* document the change in What's New in Python 3.6
* cleanup also PyCode_Optimize() to use better variable names

a module. Thanks to Rose Ames for the patch.
