1fd7940494 Ensure that error ORA-24816: Expanded non LONG bind data supplied after actual 
LONG or LOB column" is not raised by ensuring an empty string does not use a
size of zero (which triggers this situation in Oracle 12.1).

1bd8e95807 Added support for closing the connection when reaching the end of a code block 
controlled by the connection as a context manager, but in a backwards
compatible way (https://github.com/oracle/python-cx_Oracle/issues/113).

cf19bc7f74 Remove unnecessary type checks since PyFloat_AsDouble() will convert the value 
to floating point if possible anyway, and if not, will raise an appropriate
exception.

3d8b74e77f Ensure that a call to setinputsizes() with an invalid type prior to a call to 
executemany() does not result in a type error, but instead gracefully ignores
the call to setinputsizes() as required by the DB API
(https://github.com/oracle/python-cx_Oracle/issues/75).

c2c8d541bf On Windows, sizeof(long) = 4 which means that integers between 10 and 18 digits 
were not converted to Python correctly
(https://github.com/oracle/python-cx_Oracle/issues/70).

ece92442ab Delay initialization of the ODPI-C library until the first standalone 
connection or session pool is created so that manipulation of the environment
variable NLS_LANG can be performed after the module has been imported
(https://github.com/oracle/python-cx_Oracle/issues/36); this also has the added
benefit of reducing the number of errors that can take place when the module is
imported.

1f917aafbb In certain cases where non-long values follow LOB values in the list of bind 
variables, the error "ORA-24816: Expanded non LONG bind data supplied after
actual LONG or LOB column" is raised; this occurs if the length of the supplied
value, when expanded, might exceed 4000 bytes
(https://github.com/oracle/python-cx_Oracle/issues/50).
