- Got rid of the fixed array that kept the stream count in the first element and 255 streams after it.
...
- Changed streams from UCHAR to ULONG as Dmitry wanted
- Got rid of some redundant flags to indicate BLR level
- Misc changes (for example, converted to test for DBB_read_only in Database to a function)
- BLR v6 is left commented (waiting for a better solution to appear, if any exists)
- This change is not going to raise the engine limits until a solution is found to express more than 255 streams in BLR.

Include platform definitions file common.h in firebird.h. Use OS-specific ThreadId instead artificial FB_THREAD_ID, avoiding unneeded casts in the code. This should fix BSD and MAC ports.

2) Created ExprNode::expressionEqual method to replace a new big and ugly switch.
3) Make boolean referencers use BoolExprNode instead of jrd_nod, except nod_validate for now. This includes BinaryBoolNode and NotBoolNode working without jrd_nod references.
4) Rework in the impure allocation code (replace "csb_impure += ..." by CMP_impure calls).
