qmp: qmp_send_key(): accept key codes in hex
Before the qapi conversion, the sendkey command could be used to
send key codes in hex directly to the guest. In HMP, this would
be like:
(qemu) sendkey 0xdc
However, the qapi conversion broke this, as it only supports sending
QKeyCode values to the guest. That's a regression.
This commit fixes the problem by adding hex value support down
the QMP interface, qmp_send_key().
In more detail, this commit:
1. Adds the KeyValue union. This can represent an hex value or
a QKeyCode value
2. *Changes* the QMP send-key command to take an KeyValue argument
instead of a QKeyCode one
3. Adapt hmp_send_key() to the QMP interface changes
Item 2 is an incompatible change, but as we're in development phase
(and this command has been merged a few weeks ago) this shouldn't be
a problem.
Finally, it's not possible to split this commit without breaking the
build.
