[myhdl-list] Signal getattr and setattr

[Christopher L. F. <chr...@gm...>]

Attached is a patch with some modification to __getattr__ and adds the 
__setattr__ in _Signal.py.

I like the idea that the Signal class is "transparent".  Meaning that 
the object that the Signal contains, its (the contained object) 
attributes and properties can be accessed.

The change checks the "slots" before accessing the "objects" (self._val) 
attributes.

The patch fixes the bug I previously posted, max recursion depth.

I think I generated the bundle/patch correctly and tried to verify with 
a separate repository clone.  The workspace I created the bundle from 
has additional changes (mainly error/warning statements and prints) that 
are not ready to be pushed.  The only changes should be the couple lines 
in _Signal.py
