cc700b54b8 * Implemented TBufDataset.UniDirectional property 
* Run all tests of TestDBBasics also using UniDirectional TBufDatasets. (Introduces a lot of false failures)

cb92994356 * New property TSQLConnection.FieldNameQuoteChars, these chars (start- and 
end -quote) are used around field-names. Parameter-names are always quoted
   using double-quotes, since they are replaced by sqldb for all systems which
   don't use double-quotes as fieldnamequotechars. Bug #12275.

a4a1cd76e5 * Do only add parentheses when necessary for filtering. So that when the 
query parser fails this only leads to problem when the filter is used

3f98f6a5d0 * When a dataset is closed and it is not prepared it is assumed that a 
problem occured, and unprepare is called to clean everything up. But in
   case the dataset is read from a data-packet, the dataset is also not
   prepared but no problem occured, so do not call unprepare
 * Always use AllocateCursorHandle to allocate a cursor, or else its type
   can be different from what the connection expects

* TIBConnection now sets the statement type of a call to a stored procedures to stExecProcedure. This also works for "insert into .. returning" queries. (+test)
