Subject: [PATCH] imDefLkup: verify that a pointer isn't NULL before using it
It is possible for _XimICOfXICID() to return NULL, so it is necessary
to check this isn't actually the case before dereferencing the pointer.
All other callers of _XimICOfXICID() do this check too.
(The check itself is ugly, but it follows the style of the code in the
rest of the module.)
Fixes issue #45.

Subject: [PATCH libX11 1/7] ximcp: Unmark to fabricate key events with
XKeyEvent serial
_XimProtoKeypressFilter() and _XimProtoKeyreleaseFilter() can
receive XKeyEvent from both the typing on the keyboard and the
callback of XIM_FORWARD_EVENT.
If the filter functions unmark to fabricate XKeyEvent from the typing
on the keyboard during receiving XKeyEvent from the callback of
XIM_FORWARD_EVENT with typing keys very quickly likes an bar code
scanner (or evemu-play), XIM server cannot receive some key events and
it causes the key typing order to get scrambled.
Now XIM client saves the serial in XKeyEvent and the filter functions
unmark to fabricate XKeyEvent from the callback of XIM_FORWARD_EVENT
only.
This and 024d229f are same patches but the regression issues will be
fixed by the later patches.
Closes: #198

Subject: [PATCH libX11 4/7] ximcp: Add fabricated_time in XimProtoPrivate for
timeout
When users type keys quickly, some applications using Steam or Java
do not call XNextEvent() for a key event but _XimFilterKeypress()
and _XimFilterKeyrelease() expect to receive the key events
forwarded by input methods.
Now fabricated_time Time value is added to XimProtoPrivate to check
the timeout value.

Subject: [PATCH libX11 5/7] Accept anon windows in XFilterEvent to update XIM
state
When input focuses are switched quickly with shortcut keys in a Java
window, the focus is sometimes lost and the Window=0 is assigned in
XFilterEvent() but the XKeyEvent was forwarded by a XIM serer(IBus)
with XIM_FORWARD_EVENT -> XNextEvent() -> XFilterEvent() and the event
needs to be forwarded to the XIM XKeyEvent press and release filters
to update the XIM state with Window=0 likes _XimPendingFilter() and
_XimUnfabricateSerial().
Closes: #205, #206
Fixes: 024d229f ("ximcp: Unmark to fabricate key events with XKeyEvent serial")
Part-of: <https://gitlab.freedesktop.org/xorg/lib/libx11/-/merge_requests/246>
(cherry picked from commit 5a1e62d77b65ba148b1c6d1d22a81dc2b07e7d9e)

Subject: [PATCH libX11 6/7] ximcp: Unmark fabricated with serial 0 and Xic
commit_info
GTK2 XIM resets the XKeyEvent serial to 0 even if _XimCommitRecv()
sets the serial so now checks if the events are sent with
Xic->private.proto.commit_info.

Subject: [PATCH libX11 7/7] imDefIm: Add LIBX11_ENABLE_FABRICATED_ORDER env
If an XIM application does not return the XKeyEvent from XNextEvent()
to XFilterEvent(), a timeout is reached and the behavior is fallen
back to the previous one with a warning messsage and we can ask
the application to send the XKeyEvent to XFilterEvent() but also
libX11 provides LIBX11_ENABLE_FABRICATED_ORDER environment variable.
If the application runs with LIBX11_ENABLE_FABRICATED_ORDER=0, the
previous behavior is available until the application is fixed.
