Subject: [PATCH] Use Variant.unpack() instead of Variant.dup_strv().
Variant.dup_strv() returns a tuple in pygobject 3.2, e.g. (['<Control>space'], 1L), and a list in pygobject 3.4, e.g. ['<Control>space'] .

Subject: [PATCH] client: Queue events while the IBus context isn't ready
There are actually 3 patches here.
---
client: Queue events while the IBus context isn't ready
We may lose events that ought to be processed while the IBus context
isn't ready or if the connection to IBus isn't fully established yet.
To avoid that, enqueue events to be processed later when the IBus
context creation finishes.
---
client: Don't cancel an ongoing create input context on another request
This would only add more delays.
---
client: Cancel any ongoing create input context request on finalize
