[improvement] Firebird 5.0 Trace, parameter logging

[pbhofstede2]

When tracing, parameters are logged, very nice.
Currently we use CHAR(16) CHARACTER SET OCTETS to store ID-values.

Tracing log them like this.
param0 = varchar(16), " ßFÃ/¿J¹Z3¡õñ]["

I can manually convert this to hex by Win1252 decoding, (DF46C32FBF4AB95A33A1F5F15D5B) but it would be much easier to have a Hex presentation when parameter is of Octets charset.
Please implement encoding with hex-values when parameter is of type CHAR(16) CHARACTER SET OCTETS.
