* A reimplementation of itoa(), as this is not available

* that fits us well, so it is no longer plain itoa().
*
* This method works with the US-ASCII alphabet. If you port this
* to e.g. EBCDIC, you need to make a small adjustment. Keep in mind,
* that on the wire it MUST be US-ASCII, so basically all you need
* to do is replace the constant '0' with 0x30 ;).
*
* \param pBuf Caller-provided buffer that will receive the
* generated ASCII string.
*
* \param iLenBuf Length of the caller-provided buffer.
*
* \param iToConv The integer to be converted.
