--- buffer variable moved to the heap;
--- return type changed to int, returning 0 for success;
--- chain of dependency updated to propagate the error.
-- added size in the function parameters;
-- BUFFER_ERROR returned in case of message overflow (piece larger than the hello size);
-- OPAQUE24_LEN used whenever 3 bytes are needed;
-- removed unnecessary variable i;
-- Moved BUFFER_E check outside of the while, check against certSz is not needed, in this case the problem is a malformed packet since certSz can never be bigger than listSz.
-- added size in the function parameters;
-- BUFFER_ERROR returned in case of message overflow (piece larger than the hello size);
-- ENUM_LEN and OPAQUE8_LEN used whenever 1 byte is needed;
-- OPAQUE16_LEN used whenever 2 bytes are needed;
-- removed unnecessary variables (signature, sigLen);
-- removed unnecessary #ifdef HAVE_ECC.
-- added size in the function parameters;
-- BUFFER_ERROR returned in case of message overflow (piece larger than the message size);
-- OPAQUE16_LEN used where 2 bytes are needed.
-- added size in the function parameters;
-- BUFFER_ERROR returned in case of message overflow (piece larger than the message size);
-- OPAQUE16_LEN used where 2 bytes are needed.
-- added size and totalSz in the function parameters;
-- BUFFER_ERROR returned in case of message overflow (piece larger than the message size);
-- INCOMPLETE_DATA returned in case of buffer overflow (piece smaller than the expected size);
-- removed unnecessary variable mac;
-- added size and totalSz in the function parameters;
-- BUFFER_ERROR returned in case of message overflow (piece larger than the message size);
-- INCOMPLETE_DATA returned in case of buffer overflow (piece smaller than the expected size);
-- removed unnecessary variable idx;
-- fixed the sniffer to adapt to the changes.
-- switched from totalSz to size in the function parameters;
-- BUFFER_ERROR returned in case of message overflow (piece larger than the hello size);
-- ENUM_LEN used whenever 1 byte is needed;
