3.0M2 testing progress

[Andrus Adamchik]

I've started some M2 local testing, fixing things that I deemed  
important for M2 and opening Jiras for the rest. Here is the results  
so far:

PostgreSQL (passed)
MySQL (passed)
HSQLDB (passed)
Derby (one issue - CAY-897)
FrontBase (one issue - CAY-898)
I will do Oracle/Sybase/... in the next couple of days.
