* \brief Convert data into base64 encoded text.

* Notes:
*\li The base64 encoded text in 'target' will be divided into
* words of at most 'wordlength' characters, separated by
* the 'wordbreak' string. No parentheses will surround
* the text.
*
* Requires:
*\li 'source' is a region containing binary data
*\li 'target' is a text buffer containing available space
*\li 'wordbreak' points to a null-terminated string of
* zero or more whitespace characters
*
* Ensures:
*\li target will contain the base64 encoded version of the data
* in source. The 'used' pointer in target will be advanced as
* necessary.
