Subject: [PATCH] Fix not to SEGV ibus-ui-gtk3 with wrong 'preload-engines'
value.
Fedora internal patch could save engines from the result of
'setxkbmap -query' but they do not exist in simple.xml likes
'xkb:cn::chi' while now the current implementation converts
those engines to 'xkb:us::eng'.

Subject: [PATCH] Carry current context content type into fake context when
switching
When focus moves out of a context to the fake context we should keep
the content type properties as they were in the focused out context.
This allows panel implementations to show the proper UI while input
focus moves away temporarily from a text entry.
E.g. a password entry is focused and the user clicks on the panel
UI. At this point ibus switches the currently focused context to the
fake context and emits set-content-type with the fake context
properties which are empty and thus the panel reacts to it. This isn't
the intended behavior though since, from a user POV, the password
entry is still the context that will be getting text input when the
panel UI gets dismissed.

Subject: [PATCH] IMdkit: Track window property offsets correctly
The XIM specification requires that XIM tranports over 20 bytes in size
be transferred via window properties. The sender calls XChangeProperty
with PropModeAppend, and instructs the recipient via ClientMessage to
call XGetWindowProperty with delete set to True.
Naive implementations exhibit a race condition because the receiver
could have written more data in the meantime, and XGetWindowProperty
only deletes the property when bytes_after_return is zero. If
bytes_after_return is non-zero, it is necessary to use an offset when
reading from the property again.
To ensure that the property data does not grow indefinitely, Xlib
recycles 21 Atoms in round-robin fashion. Because the XIM specification
does not limit the number of Atom names of the form "_clientXXX" to be
used for data transfer over window properties, an XIM server should be
able to keep of track any number of Atoms, remembering the offset into
each property.
This patch implements correct tracking of property offsets.
