NEED_SYNC_REPLY flag should be in Xim not in Xic.
Because the focused Xic can be changed before sending sync reply.
After focused Xic changed, the new Xic doesn't have NEED_SYNC_REPLY
flag enabled, so libX11 doesn't send XIM_SYNC_REPLY packet.

This patch adds sync reply flag to Xim and removes sync reply
from Xic.
