Set a feature to prevent versions older that 2.6.20 from loading a
database from which they cannot read the dates. Ideally we would do this
only if the database is written to, but the current persistence design
includes committing back to the database during the load so the net
effect is that the flag would be set anyway.
This commit introduces a new feature flag:
GNC_FEATURE_GUID_FLAT_BAYESIAN. It signifies that the bayes import map
data are stored flat and by guid. Any time bayes import map data are
accessed, they are converted if necessary.
This will avoid a ninja-build from picking up a config.h generated by the autotools build
(in the root build directory). Picking up the wrong config.h may lead to all kinds of
subtle issues if the autotools run was done with different options than the cmake run.
It is split into
- /libgnucash (for the non-gui bits)
- /gnucash (for the gui)
- /common (misc source files used by both)
- /bindings (currently only holds python bindings)
This is the first step in restructuring the code. It will need much
more fine tuning later on.
