The issue was: for MacOS/clang, the virtual format-specific
option structs had to be embedded in one compile unit (for RTTI).
In Windows this will lead to link errors since the DLL is not
reachable at build time for the generic reader/writer configuration in
the buddy tools.
The solution is to use GSI methods (provided for scripting) to
set the reader/writer options in a generic way that does not
require linking against the plugin DLLs.
The goal of the refactoring is to support unit tests
for the db library.
For this, a distributed unit test concept has been
introduced (later to be extended to other libs).
Unit tests are shared objects called ".ut" and are
automatically loaded by the ut runner. The bd library
now has two folders - one for sources and one for the
unit tests. The sources are separated into lib and apps.
First unit tests for the writer options have been
provided.
