4058f363d6 More robust RealDictRow population 
In the presence of repeated columns the mapping would have remained into
into the dictionary. Now it is removed.

Fix #884

cc815e8e8d RealDictRow inherits from OrderedDict 
Now its state is unmodified, so apart from special-casing creation
and initial population can work unmodified, and all the desired
properties just work (modifiability, picklability...)

Close #886.

3f890f8bbe Use True/False instead of 1/0 to represent bool values 
Slightly more modern, readable, and Pythonic.

35ec7ad9c1 Use a proper LRU cache for namedtuples 
Previous one didn't refresh by last use. Use the stdlib version for py3
and one of our own for py2.

Max size set to 512, which should be fine for everyone (tweaking is
still possible by monkeypatching, as the tests do, but I don't want to
make an interface of it).

bc84b6233e Allow non-ascii chars in namedtuple fields 
They can be valid chars in Python 3. Or maybe not? In which case Python
will throw an exception, but that's fine.

8ad2098b74 Drop 2to3 build step; make all code compatible with all Pythons 
Make all library code compatible with both Python 2 and Python 3. Helps
move to modern Python idioms. Can now write for Python 3 (with
workarounds for Python 2) instead of the other way around.

In the future, when it is eventually time to drop Python 2, the library
will be in a better position to remove workarounds

Added a very small comparability module compat.py where required. It
includes definitions for:

- text_type -- A type. str on Python 3. unicode on Python 2.
- string_types -- A tuple. Contains only str on Python 3. Contains str &
                  unicode on Python 2.

19b1efd629 Drop long deprecated function register_tstz_w_secs() 
Deprecated in commit b263fbf274 on
2010-01-13. The deprecation warning was first released in version 2.2.2.

The function used to register an alternate type caster for TIMESTAMP
WITH TIME ZONE to deal with historical time zones with seconds in the
UTC offset. These are now correctly handled by the default type caster,
so currently the function doesn't do anything.
