Enables full functionality for complex-boolean and multichoice-callback
options.
Note that setter-function callback isn't used in any GnuCash code so it
is not implemented and is not present in the register-callback functions.
The root cause of which is that on recent releases of GLib (recent
meaning 2.66 in the current Debian stable!) g_type_instance_get_private
looks in the wrong place for the private data. When running the script
in question it returned NULL and since the code didn't check for a valid
pointer, it crashed.
So this change replaces all calls to g_type_instance_get_private with
the function [type_prefix]_get_instance_private() added in glib-2.36
except for two register2 files that have been removed from master; those
are ignored to avoid unnecessary merge conflicts.
Separate the "All noncurrency" convenience category in the commodity
selector and the default non-commodity namespace proposed by the QIF
importer because they have different functions.
Also remove the namespace guessing code from qif-dialog because with
only one default non-currency namespace there's nothing to guess.
Python bindings already have some wrapping objects for
qof predicates. This adds the one missing for GncNumeric
comparisons.
Additionally fixes a wrong number for QOF_NUMERIC_MATCH_ANY
in example file.
Leave it to users to categorize their non-currency commodities. In the
QIF importer default non-classifiable commodities to
GNC_COMMODITY_NS_NONCURRENCY.
The original merge was of a PR based on master into maint, bringing
along all of the development changes in master along with it. We don't
want that so the merge was reverted and the PR's two changes
cherry-picked in. That fixed maint, but then the next regular merge of
maint into master naturally included that revert commit undoing the
changes in master. Not so good. Reverting the revert, this commit,
restores the changes, albeit with messed up history.
