1. Workaround for Oracle ODBC driver for Linux. Number of fetched rows is
not set,
   therefore one should calculate this number ourself.
2. TODBCServer::GetDrivers() and TODBCServer::GetDataSources() static
methods are implemented.
   They provide information about available configured ODBC drivers and data
sources respectively.
   Also PrintDrivers() and PrintDataSources() methods are implemented.
3. TODBCServer::ServerInfo() method is implemented. It nows returns server
name and version like:
     "Oracle 10.01.0030" or "MySQL 4.1.11"
   TMySQLServer::ServerInfo() modified to return info in form: "MySQL
4.1.11"
4. TODBCServer::GetTablesList() modified in respect of Oracle ODBC driver
functionality -
    wildcarding is now works correctly.
