	** Fixes #565149 - by Daniel Morgan  <monodanmorg@yahoo.com>
	* System.Data.OracleClient/OracleParameter.cs:
	- if programmer explicitly sets the Size property,
	do not override the size later if the Value property
	is set for character data.
	- for character and numeric data types, output and
	return parameters were not allocated memory.
	Also, input/output parameters need to allocate memory
	based on Size because the output can be bigger than
	the input after an execute.

	* Test/TestOracleClient.cs: Data Adapter Test 2 is failing
	for NET_2_0 profile.
