XKB: fix XkbGetKeyboardByName with Xming server
XkbGetKeyboardByName relies on flags to read the data from the server. If the X server sends us the wrong flags or if a subreply is smaller than it should be, XkbGetKeyboardByName will not read all the available data and leave data in the buffer, which will cause the next _XReply() to fail with: [xcb] Extra reply data still left in queue [xcb] This is most likely caused by a broken X extension library [xcb] Aborting, sorry about that. xcb_io.c:576: _XReply: Assertion `!xcb_xlib_extra_reply_data_left' failed. Aborted Check if there is some extra data left at the end of XkbGetKeyboardByName() and discard that data if any is found. Many thanks to Peter Hutterer <peter.hutterer@who-t.net> for finding the root cause of the issue and Adam Jackson <ajax@redhat.com> for helping with the analysis!
