Previously there were no functions in the simple API that return the
matched attributes other than the secret value, while there were needs
for augumenting user input with additional information (such as
completing web forms).
This adds a set of functions which wrap secret_service_search*. Note
that the return value is a list of GHashTable not of SecretItem,
because SecretItem is a subclass of GDBusProxy, which we don't want to
expose from the simple API.
Fixes#16
* When passing NULL for a string vararg attribute print
a critical warning.
* Make all attribute warnings critical
* Add tests for the various critical warnings
https://bugzilla.gnome.org/show_bug.cgi?id=686015
* It's clearer what happens here: we try to remove as many matching
passwords as possible.
* Also rename secret_service_remove() to secret_service_clear()
* Rename secret_password_clear() which used to wipe password memory
to secret_password_wipe().
* Death by a thousand paper cuts from gir and vapi not liking
the fact that the secret.h file was not usable uninstalled
and installed in the same way.
