OpenDBX 1.3.4

OpenDBX is an extremely lightweight but extensible C library for accessing databases with a single API.
OpenDBX provides a clean and simple interface across all supported databases that leads to an elegant code design automatically. Currently supported databases are:
- Firebird
- Interbase
- MS SQL Server
- MySQL
- PostgreSQL
- SQLite
- SQLite3
- Sybase
Backends for more native database APIs can be written easily. If you want your application to support different databases with little effort, this is definitively the right thing for you!
Enhancements:
- This release adds the C++ interface for the large object functions, the missing Conn::getCapability() member function, and the regression test code for libopendbxplus.
- For more control over loading the backend modules, its now possible to supply the full path to the backend library as the first parameter to odbx_init().
- Also, there was a change of the parameter type of odbx_lo_open() as well as a change regarding the visibility of the C++ class variables.
- Finally, the pgsql backend returned partly wrong results for boolean values if odbx_field_value() was called twice. This is fixed now.
