27421f1e41 Name can be passed as None to cursor() 
Makes invocation from subclasses and generic code easier.

Code simplified by using default values for keyword arguments
and avoiding needless conversions back and forth between Python and C
strings. Also added connection type check to cursor's init.

7221ea9ec5 Added test to check rowcount behaves fine during named cursor iteration 
Actually *it doesn't*: once we iterate the first itersize records, rowcount
is reset to zero. If we want to fix it we need an extra member in the
cursor.

ad3a198919 Fixed reference leak with arguments referenced more than once in queries 
Plus, some more care in objects life cycle, mostly in exceptions handling.

Closes ticket #81.

c620f18be1 Provide cursor.description as named tuple if possible 
If namedtuple() is not available, use regular tuples.

99b3c72312 Some cleanup in mogrify 
- Raise an exception on incomplete placeholders.
- Minor speedups.
- Don't change the string in place (??!!) if the placeholder is not s
  and the value is null.

The latter point can be done because downstream we don't accept anything
different from s anyway (in the Bytes_Format function).

Notice that now the format string is constant whatever the arguments.
This means that executemany is still more inefficient than it should be
as mogrify may work only on the parameters. However this is an
implementation only worthwhile if we start supporting real parameters.

Let's talk about that for the next release.

63ac6cdde5 Added cursor.itersize 
The value is used to control the number of records to fetch per network
roundtrip in named cursors iteration. Used to avoid the inefficient
arraysize default of 1 without giving this value the magic meaning of
2000.

159cda3688 Added cursor.cast() method 
The method exposes the typecasters lookup algorithm. Useful to create
recursive typecasters.

ade1b2cc7b Test suite converted into a proper package. 
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.
