Allows removing many duplicate imports and better follows PEP8
guidelines:
https://www.python.org/dev/peps/pep-0008/#imports
> Imports are always put at the top of the file, just after any module
> comments and docstrings, and before module globals and constants.
Rather than deleting, the class, use the skip feature. Provides a more
informative message during test output.
Never skip DatetimeTests as all supported Python environments have the
datetime module builtin.
The tests relied on Python2 relative import semantics. Python3 changed
import semantics to always search sys.path by default. To import using a
relative path it must have a leading dot.
Forward compatible with newer Pythons.
Works towards the goal of moving tests outside of the installed package.

There is no need to import testutils.unittest instead of simply
unittest. They are simple aliases. Use system unittest to be more
regular, consistent as well as idiomatic with the wider Python
community.
It was registered as side effect of an excessive definition that got
cleaned up in 338dbe70a6.
Looking at other removed redundant type oids, this was the only one
missing from the `string_types` map.
Close#578.
Should close#558, but I'm curious to know if a number is returned
for interval < 1 day too (which wouldn't trigger the overflow, but will
finish parsing with part=0).
(almost... except for micros rounding)
While this is probably an improvement on the previous implementation,
I am largely waving a dead chicken at windows, which keeps failing to
pass the seconds overflow test. If it doesn't pass now either I'll start
blaming Python's timedelta.
Named cursors on old server versions have a different prefetch behaviour.
This has hidden me the supported range of the 24:00 time format.
Let's have another go at full testing...
Avoid creating new a new FixedOffsetTimezone instance if one with the
same offset and name has been created before. This will save memory
when returning many rows containing "timestamp with timezone" columns,
and also improves comparability.
The offset displayed was always positive and somewhat confusing. The
offset displayed now is the offset that the instance was created
with.
Also added some tests for initialisation.
Dropped cyclic import from modules to tests: they were only working
because a second copy of the package was found in the project dir.
Use relative import so that 2to3 can do a good conversion.
Allow the objects to be recognized as the proper type by Postgres in not
strong contexts: problem reported by Peter Eisentraut.
Added tests to check the types are respected in a complete Py -> PG ->
Py roundtrip without context.
coverage for datetime and time strings with and without time zone
information.
* psycopg/typecast_datetime.c (typecast_PYDATETIME_cast): adjust
to handle the changes in typecast_parse_time.
(typecast_PYTIME_cast): add support for time zone aware time
values.
* psycopg/typecast_mxdatetime.c (typecast_MXDATE_cast): make sure
that values with time zones are correctly processed (even though
that means ignoring the time zone value).
(typecast_MXTIME_cast): same here.
* psycopg/typecast.c (typecast_parse_time): Update method to parse
second resolution timezone offsets.
