Issue 26069: Remove the Deprecated API in trace module

A number of old methods in trace module were deprecated in issue10371. They should be removed in 3.6 release.

This patch removes the deprecated apis from 3.6. After getting a review from one another core dev, I will commit this.

* No doc changes are required as the deprecated apis were not documented.
* README will be added during commit.

You seem to have forgotten to include a patch.

Sorry for that. Here is the patch.

Thanks for the review, matrixise. I've submitted this change.

I couldn't find exact references, but I think we've reached an agreement that we want to keep old APIs in the stdlib to make porting from Python 2 easier. So you might want to revert this :)

Hi Berker, could you find the reference for it? It will be helpful to analyze.
IMO, the non-removal of 2.x-> 3.x APIs could be done on a case to case basis.

In this case, issue10371 made the change in (2010) of making the undocumented public methods to private internal and deprecated those old undocumented internal (but public) methods. It was a correct thing to do. Removal of the deprecated should have been done sooner. Otherwise, we are left with redundant methods (public and _private) in the same module serving no useful purpose.

Sorry, I don't have much time investigate this further, but here is a few references from my bookmarks:

* http://bugs.python.org/msg253473 (from issue 20438)
* https://hg.python.org/peps/rev/570913685f49 (this doesn't mention old APIs, but I think we can safely follow it for old APIs)

Another discussions about deprecation policy: issue 24203 (old threading API), issue 25486 (inspect.getargspec()) and issue 26041 (platform.dist() and platform.linux_distribution())

If you want to keep the old API removed, it would be great to add a note in Doc/whatsnew/3.6.rst in addtion to the Misc/NEWS entry.

Thanks for the pointers, Berker. That was very helpful and I will keep in mind when evaluating other deprecated apis. 

For the trace module, I will add this removal information in Doc/whatsnew/3.6.rst
