API: Introduce value and datatype structs to Extern C
Summary
See #22 (closed). Introduce datatype and value structs to the Extern C interface which are then used to set and get property and entity values and datatypes. For this, an AbstractValue class was introduced to libcaosdb.
Focus
The former implementations of the caosdb_entity_{property,entity}_get_<type>_value
functions have been replaced by the corresponding get functions that operate on value structs. In the same way, the former ..._{set,get}_datatype(char *, bool, bool)
functions have been replaced by the corresponding caosdb_entity_datatype_is_<type>
and caosdb_entity_datatype_get_datatype_name
functions. The tests in test_ccaosdb
have been adapted and extended.
Test Environment
Unit and integration tests should be sufficient.
