scsi: fix searching for an empty id
The conditions for detecting no free target or LUN were wrong.
The LUN loop was followed by an "if" condition that is never
true, because the loop is exited as soon as lun becomes equal
to bus->info->max_lun, and never becomes greater than it.
The target loop had a wrong condition (<= instead of <). Once
this is fixed, the loop would fail in the same way as the LUN
loop.
The fix is to see whether scsi_device_find returned the device with the
last (channel, target, LUN) pair, and fail if so.

i8254: Rework & fix interaction with HPET in legacy mode
When the HPET enters legacy mode, the IRQ output of the PIT is
suppressed and replaced by the HPET timer 0. But the current code to
emulate this was broken in many ways. It reset the PIT state after
re-enabling, it worked against a stale static PIT structure, and it did
not properly saved/restored the IRQ output mask in the PIT vmstate.
This patch solves the PIT IRQ control in a different way. On x86, it
both redirects the PIT IRQ to the HPET, just like the RTC. But it also
keeps the control line from the HPET to the PIT. This allows to disable
the PIT QEMU timer when it is not needed. The PIT's view on the control
line state is now saved in the same format that qemu-kvm is already
using.
Note that, in contrast to the suppressed RTC IRQ line, we do not need to
save/restore the PIT line state in the HPET. As we trigger a PIT IRQ
update via the control line, the line state is reconstructed on mode
switch.

Make -machine/-enable-kvm options merge into a single list
Make the "machine" option list use list merging, so that multiple
-machine arguments (and the -enable-kvm argument) all merge together
into a single list. Drop the calls to qemu_opts_reset() which meant
that only the last -machine or -enable-kvm option had any effect.

the '-enable-kvm' option, and "-machine foo -enable-kvm" would
ignore the '-machine foo' option.
