/* Function: Filter ============================================================
* Abstract:
* Filter the outgoing message to translate any bytes that conflict with
* escape chars. If a byte does conflict, the byte is replaced with two
* bytes: The first is the escape character and the second is the conflicted
* byte exclusive or'd with the mask character. If a byte does not conflict,
* it is unchanged. Returns the new size of the buffer after filtering.
*
* Note: In the worst case where every char is an escape char, the
* destination buffer will be 2 times the size of the source buffer.
