/**
@brief: This function is used to Aggregate the formated buffer, this
also check the overflow condition and adds the overflow message
to the end of the log Dump buffer reserved of MAX_OVERFLOW_MSG size.
@param: tpAniSirGlobal pMac
@param: char *pBuf
@param: variable arguments...
@return: Returns the number of bytes added to the buffer.
Returns 0 incase of overflow.
@note: Currently in windows we do not print the Aggregated buffer as there
is a limitation on the number of bytes that can be displayed by DbgPrint
So we print the buffer immediately and we would also aggregate where
the TestDbg might use this buffer to print out at the application level.
