This class takes care of details of the trace facility;
a derived class should implement user interaction.
The standard debugger class (pdb.Pdb) is an example.
The optional skip argument must be an iterable of glob-style
module name patterns. The debugger will not step into frames
that originate in a module that matches one of these patterns.
Whether a frame is considered to originate in a certain module
is determined by the __name__ in the frame globals.

For real filenames, the canonical form is a case-normalized (on

angle brackets, such as "", generated in interactive
mode, are returned unchanged.

aO Dispatch a trace function for debugged frames based on the event.
This function is installed as the trace function for debugged
frames. Its return value is the new trace function, which is
usually itself. The default implementation decides how to
dispatch a frame, depending on the type of event (passed in as a
string) that is about to be executed.
The event can be one of the following:
line: A new line of code is going to be executed.
call: A function is about to be called or another code block
is entered.
return: A function or other code block is about to return.
exception: An exception has occurred.
c_call: A C function is about to be called.
c_return: A C function has returned.
c_exception: A C function has raised an exception.
For the Python events, specialized functions (see the dispatch_*()
methods) are called. For the C events, no action is taken.
The arg parameter depends on the previous event.

Whether a break should happen depends on the way that b (the breakpoint)
was set. If it was set via line number, check if b.line is the same as
the one in the frame. If it was set via function name, check if this is
the right function and if it is on the first executable line.

The "active breakpoint" is the first entry in bplist[line, file] (which
must exist) that is enabled, for which checkfuncname is True, and that
has neither a False condition nor a positive ignore count. The flag,
meaning that a temporary breakpoint should be deleted, is False only
when the condiion cannot be evaluated (in which case, ignore count is
ignored).
If no such entry exists, then (None, None) is returned.
