issue13183 - Fix pdb skipping frames after hitting a breakpoint and running step. Patch by Xavier de Gaye

issue13183 - Fix pdb skipping frames after hitting a breakpoint and running step. Patch by Xavier de Gaye

Many tests simply didn't care if they unset a pre-existing trace function. This
made test coverage impossible. This patch fixes various tests to put back any
pre-existing trace function. It also introduces test.support.no_tracing as a
decorator which will temporarily unset the trace function for tests which
simply fail otherwise.

Thanks to Kristian Vlaardingerbroek for helping to find the cause of various
trace function unsets.

Show the traceback line numbers as well as the current line numbers if an exception is being debugged.  Courtesy of pdb++ by Antonio Cuni.  Also document -> and >> markers for "list".

* added basic test for basic commands
* removed duplication of command docs, and moved them to their implementation
* unified and useful display of exceptions
* output messages and errors using overridable methods (also fixes #1503502)

#809887: improve pdb feedback for breakpoint-related actions.  Also add a functional test for these commands.

#1472251: remove addition of "\n" to code given to pdb.run[eval](), the bug in exec() that made this necessary has been fixed.  Also document that you can give code objects to run() and runeval(), and add some tests to test_pdb.
