I don't know why it has been choosen to move to a metaclass but it actually
brings more problems and a more complex code that it brings benefits.

Actually the old compatibility code actually prevented this bug so back it up.

There was a missmatched combination of:

* the frame wasn't always correctly grabbed
* grabbing the frame in the situation of a decorator didn't make any sens, so
  switch to func.__module__
* the tests were bad and expected "[logilab.common]" while it should have been
  "[test_deprecation]" because it was there that the depreciation was declared

Taken from yams taken from nemo

[deprecation] use send_warning in attribute/argument_renamed, argument_removed and DeprecationWrapper
