In commit 802cbcb730, most issues have been fixed when qemu guest
migration. But the queue size still need to check whether is equal to
PS2_QUEUE_SIZE. If yes, the wptr should set as 0. Or, wptr would larger
than PS2_QUEUE_SIZE and never come back when ps2_queue_noirq is called.
This could lead to OOB access, add check to avoid it.

MacOS 9 has a bug in its PMU driver whereby after configuring the ADB bus
devices it sends another write to reg 3 on both devices resetting them
both back to the same address.
Add a new disable_direct_reg3_writes property to ADBDevice to disable these
direct writes which can enabled just for the upcoming pmu-adb support.

This allows guest's to correctly reinitialize and identify the mouse
should the guest decide to re-scan or reset during mouse input events.
When the guest sends the "Identify" command, due to the PC's hardware
architecutre it is impossible to reliably determine the response from
the command amongst other streaming data, such as mouse or keyboard
events. Standard practice is for the guest to disable the device and
then issue the identify command, so this must be obeyed.

NB, the virtio-input device reports a bitmask to the guest driver that
has a bit set for each Linux keycode that the host is able to send to
the guest.
Thus by adding these extra key mappings we are technically changing the
host<->guest ABI. This would also happen any time we defined new mappings
for QEMU keycodes in future.
When a keycode is removed from the list of possible keycodes that host can
send to the guest, it means that the guest OS will think it is possible
to receive a key that in pratice can never be generated, which is harmless.
When a keycode is added to the list of possible keycodes that the host can
send to the guest, it means that the guest OS can see an unexpected event.
The Linux virtio_input.c driver code simply forwards this event to the
input_event() method in the Linux input subsystem. This in turn calls
input_handle_event(), which then calls input_get_disposition(). This method
checks if the input event is present in the permitted keys bitmap, and if
not returns INPUT_IGNORE_EVENT. Thus the unexpected event will get dropped,
which is harmless.
If the guest OS reboots, or otherwise re-initializes the virt-input device,
it will read the new keycode bitmap. No matter how many keys are defined,
the config space has a fixed 128 byte bitmap. There is, however, a size
field defiend which says how many bytes in the bitmap are used. So the guest
OS reads the size of the bitmap, and then it reads the data from bitmap upto
the designated size. So if the guest OS re-initializes at precisely the time
that QEMU is migrated across versions, in the worst case, it could conceivably
read the old size field, but then get the newly updated bitmap. If a key were
added this is harmless, since it simply means it may not process the newly
added key. If a key were removed, then it could be readnig a byte from the
bitmap that was not initialized. Fortunately QEMU always memsets() the entire
bitmap to 0, prior to setting keybits. Thus the guest OS will simply read
zeros, which is again harmless.
Based on this analysis, it is believed that there is no need to preserve the
virtio-input-hid keymaps across migration, as the host<->guest ABI change is
harmless and self-resolving at time of guest reboot.
NB, this behaviour should perhaps be formalized in the virtio-input spec
to declare how guest OS drivers should be written to be robust in their
handling of the potentially changable key bitmaps.

AT Set 2: e0 12 e0 7c (Down) e0 f0 7c e0 f0 12 (Up)
which QEMU gets right. When pressed in combination with the 'Alt_L' or 'Alt_R'
keys (which signify SysRq), the scancodes are required to follow a different
scheme. With Alt_L, the expected sequences are
AT set 1: 38, 54 (Down) d4, b8 (Up)
AT set 2: 11, 84 (Down) f0 84, f0 11 (Up)
And with Alt_R
AT set 1: e0 38, 54 (Down) d4, e0 b8 (Up)
AT set 2: e0 11, 84 (Down) f0 84, f0 e0 11 (Up)
It is actually slightly more complicated than that, because (according results
of 'showkey -s', keyboards will in fact first release the currently pressed
modifier before sending the sequence above (which effectively re-presses &
then releases the modifier) and finally re-press the original modifier
afterwards. IOW, with Alt_L we need to send
AT set 1: b8, 38, 54 (Down) d4, b8, 38 (Up)
AT set 2: f0 11, 11, 84 (Down) f0 84, f0 11, 11 (Up)

AT set 1: e0 b8, e0 38, 54 (Down) d4, e0 b8, e0 38 (Up)
AT set 2: e0 f0 11, e0 11, 84 (Down) f0 84, e0 f0 11, e0 11 (Up)
The AT set 3 scancodes have no special handling for Alt-Print.
Rather than fixing the handling of the 'print' key in the ps2 driver to consider
the Alt modifiers, way back, a patch was commited that defined an extra 'sysrq'
key name:

With this patch QEMU would send
AT set 1: 38, 54 (Down) d4, b8 (Up)
AT set 2: 11, 84 (Down) f0 84, f0 11 (Up)
but this doesn't match what actual real keyboards send, as it is not releasing
the original modifier & pressing it again afterwards. In addition the original
problem remains, and a new problem was added:
- The sequence 'alt-print-t' is still broken, acting as if 'print-t' was
requested
- The sequence 'sysrq-t' is broken, injecting an undefine scancode sequence
tot he guest os (bare 0x54)
To deal with this mess we make these changes to the ps2 code, so that we track
the state of modifier keys (Alt, Shift, Ctrl - both left & right). Then we can
vary what scancodes are sent for Q_KEY_CODE_PRINT according to the Alt key
modifier state
Interestingly, it appears that of operating systems I've checked (Linux, FreeBSD
and OpenSolaris), none of them actually bother to validate the full sequences
for a unmodified 'Print' key. They all just ignore the leading "e0 2a" and
trigger based off "e0 37" alone. The latter two byte sequence is what keyboards
send with 'Print' is combined with 'Shift' or 'Ctrl' modifiers.

[Eric Blake noted that xargs grep '%[-+ 0'I]+#' should be xargs grep
"%[-+ 0'I]+#" instead so the shell quoting is correct.

In some cases a failing VMSTATE_*_EQUAL does not mean we detected a bug,
but it's actually the best we can do. Especially in these cases a verbose
error message is required.
Let's introduce infrastructure for specifying a error hint to be used if
equal check fails. Let's do this by adding a parameter to the _EQUAL
macros called _err_hint. Also change all current users to pass NULL as
last parameter so nothing changes for them.

When the guest resets the keyboard also clear the queue. It is highly
unlikely that the guest is still interested in the events stuck in the
queue, and it avoids confusing the guest in case the queue is full and
the ACK can't be queued up.

When resetting the keyboard, we need to reset not just the pending keystrokes,
but also any pending modifiers. Otherwise there's a race when we're getting
reset while running an escape sequence (modifier 0x100).

Time to wire up all the call sites that request a shutdown or
reset to use the enum added in the previous patch.
It would have been less churn to keep the common case with no
arguments as meaning guest-triggered, and only modified the
host-triggered code paths, via a wrapper function, but then we'd
still have to audit that I didn't miss any host-triggered spots;
changing the signature forces us to double-check that I correctly
categorized all callers.
Since command line options can change whether a guest reset request
causes an actual reset vs. a shutdown, it's easy to also add the
information to reset requests.

cannot_instantiate_with_device_add_yet was introduced by commit
efec3dd631 to replace no_user. It was
supposed to be a temporary measure.
When it was introduced, we had 54
cannot_instantiate_with_device_add_yet=true lines in the code.
Today (3 years later) this number has not shrunk: we now have
57 cannot_instantiate_with_device_add_yet=true lines. I think it
is safe to say it is not a temporary measure, and we won't see
the flag go away soon.
Instead of a long field name that misleads people to believe it
is temporary, replace it a shorter and less misleading field:
user_creatable.
