As previously announced, key snooping is something that we should not
support in GTK. In particular because AT-SPI made every key press a
synchronous DBUS call / spawned a nested main loop with the key
snoopers. This breaks responsiveness, order of key presses and internal
consistency when the AT decides to remove key events.
For god-knows-what reason, at-spi is trying various formats
of strings when registering listeners, triggering g_warnings()
from gailutil code. Stop doing that.
Also, don't leak temporary string arrays that are a side-effect
of passing parameters around as formatted strings.

Due to tragic misunderstandings at the birth of ATK, AtkUtil
can't actually be properly derived. Instead, each implementation
has to poke its vfuncs directly into the AtkUtilClass struct.
So painful to have shipped this stuff for 10 years...
