base64 encode length returns size of encoded string + 1.

Key: AXIS2C-976
URL: https://issues.apache.org/jira/browse/AXIS2C-976
Project: Axis2-C
Issue Type: Bug
Affects Versions: 1.3.0
Reporter: Senaka Fernando
base64 encode length returns size of encoded string + 1, which is incorrect.
This is because we assume that someone expects the length + 1 to accommodate
'\0' that we add. But, if we gave the same string to a strlen() it returns size
of encoded string. This would confuse a potential user.
axutil_base64_encode (encoded, "senaka", 6) = 9, and strlen(encoded) = 8. Also,
axutil_base64_encode_len(6) = 9.
Therefore, I think it is better to stick to the strlen() way, especially
because popular libraries and resources adopt that strategy. Refer [1] for more
information.
