When driving QEMU from the outside, we have basically no chance to determine how quickly the guest OS picks up key events, so we usually have to limit ourselves to very slow keyboard presses to make sure the guest always has enough chance to pick them up. This patch adds a trace events when the keyboarde queue is drained. An external driver can use that as hint that new keys can be pressed.
