Hi. I'm using firebirdsql, it helps my work very much.
I think I found some bugs, I'll report it.

Some of Properties for FBDriver (e.g.
TRANSACTION_REPEATABLE_READ=concurrency,write,nowait)
will be dropped.

FBDriverPropertyManager#normalize() removes all the Properties
except ones with isc_dpb_* form.

FBDriver#connect() calls FBDriverPropertymanager#normalize(),
dropping some properties. After that it calls
FBConnectionHelper#getTpbMapper()
which looks in vain for parameters like TRANSACTION_REPEATABLE_READ.
