[r23164]Bug #684670 - Interest amount calculation is wrong in Sqllite3 format

Yet another corner where forgetting to run a edit-commit cycle when
changing state breaks database save.

[r23174]Bug #674862 - 2038 bug in libdbi

Retrieve the numerical value directly from the dbi_result and use
it to create the Timespec or GDate.

NB: In Gnucash 2.4 there are plenty of other 2038 bugs due to reliance
on the libc time functions. This has been corrected in trunk.

Don't call g_type_init in tests if Glib is v 2.36 or later.

[r23191]Fix leaking Gtkosxapplication objects.

[r23192]Bug 632362 - Unable to create "reversing transaction" again after it is removed

From leaking references in g_object_get because both g_object_get
and g_value_set_object ref the object, which is only unreffed once.
Using g_value_take_object() instead prevents the double-ref.
