Modified IStatement interface in our API: 1. Never allocate empty statement - always use att->prepare() to create statement interface 2. Separated IStatement into 2 parts - statement itself and resultset. 3. Added stmt->openCursor() (and att->openCursor() for unprepared statements) to create IResultSet. 4. Always use IMessageMetadata (former IParametersMetadata) to pass message fromat info from client, therefore avoiding need in BLR generation in client applications.

Remove FbMessage struct from the API. This struct lost its main value (group various blr-related properties in a single parameter). And since openCursor/fetch already split the message/buffer, it does not make sense anymore to have it.
