cb3f833a63 Added support for binding objects and setting attributes on objects of numbers, 
strings and dates.

b05d71b386 Use the national character set encoding if setting a value with the national 
character set needing to be used; otherwise, the wrong encoding could be used
if the environment variable NLS_NCHAR is set.

3c36e8cde3 Added support for NCHAR, FIXED_NCHAR and LONG_NCHAR, which are the same as the 
types UNICODE, FIXED_UNICODE and LONG_UNICODE (now deprecated).

faadbe4730 Remove code specific to strings being 4000 characters now that Oracle 12c has 
the ability to have strings up to 32k characters. This implies that using
setinputsizes() is necessary if a long string type is desired as this will not
occur automatically when the string exceeds 4000 characters. Tests are tidied
up to remove the "p_" prefix from all bind variables.

d255b7457f Expose the UNICODE, FIXED_UNICODE and LONG_UNICODE types so that in Python 3 
one can actually specify the use of the NCHAR type fields when binding or using
setinputsizes().

4838055084 Ensure that in Python 3 NCHAR and NVARCHAR2 and NCLOB columns are retrieved 
properly without conversion issues. Thanks to Joakim Andersson for pointing
out the issue and the possible solution.

04f1904a7d Remove "unicode" mode and simply permit unicode to be used everywhere within 
cx_Oracle; stop using "unicode" mode in the OCI as well since that appears to
have bugs in some places and doesn't really solve any problems anyway.

9be85a356c Free temporary LOBs prior to each fetch in order to avoid leaking them; thanks 
to Uwe Hoffmann for the initial patch.

c6603b324d Add new attributes size, bufferSize and numElements to variable objects, 
deprecating allocelems (replaced by numElements) and maxlength (replaced by
bufferSize); avoid increasing memory allocation for strings when using variable
width character sets and increasing the number of elements in a variable during
executemany(). Thanks to Don Reid for pointing out this issue.

515bca0f96 All test cases now run correctly in Unicode mode. There are still additional 
things that need to be dealt with but the majority of the code has now been
transformed to use either Unicode or encoded strings with Oracle.

eae705cef1 Rename additional macro as suggested by Amaury Forgeot d'Arc; added additional 
support for full Unicode; in Python 2.x allow for keyword arguments which use
strings and simply convert them to Unicode on the way through.

030d6528b5 Fix handling of unicode on narrow build machines now that byte length semantics 
are being used in all cases.

2e26d0beb8 Continued work on Unicode support; added new test cases for full unicode 
support within Python 2.x; move away from character semantics which Oracle is
deprecating anyway to byte semantics which should hopefully eliminate the
problem with a backend character set of UTF-8.

8e506ceeea Make a base type for all variables so that the attributes and methods are 
shared without having to specify such; remove references to methods that get
the attributes and methods dynamically since these are deprecated in Python 2.6
and above. Thanks to Amaury Forgeot d'Arc for the initial patch.

to facilitate migration to Python 3.0.

ea3def86c5 Added support for returning unicode values for nchar and nvarchar data and 
for binding unicode. Thanks to Amaury Forgeot d'Arc for the initial patch.
