Davi Arnaut 96a3a92c71 Bug#49141: Encode function is significantly slower in 5.1 compared to 5.0 ...

The problem was that the multiple evaluations of a ENCODE or
DECODE function within a single statement caused the random
generator to be reinitialized at each evaluation, even though
the parameters were constants.

The solution is to initialize the random generator only once
if the password (seed) parameter is constant.

This patch borrows code and ideas from Georgi Kodinov's patch.
