Enhance sendkey with key hold time (Jan Kiszka).

Browse Source 
Current key injection via the monitor basically generates no key hold
time. This is fine for keyboard emulations that have their own queues,
but it causes troubles for those how don't (like the MusicPal - it
simply does not work with injected keys). Moreover, I would like to use
this mechanism to simulate pressed buttons during power-up.

Therefore, this patch enhances the key injection with a configurable
release delay (by default 100 virtual milliseconds).

This feature allows to get rid of the initial sleep() in musicpal_init
because one can now simply start qemu with -S and issue "sendkey m 1000"
and "continue" in the monitor to achieve the desired effect of a pressed
menu button during power-up. So there is no need for a per-musicpal or
even qemu-wide "-hold-button" switch.
