Factor out the "direct kernel boot" code path from arm_load_kernel()
into its own function; this function is getting long enough that
the code flow is a bit confusing.
This commit only moves code around; no semantic changes.
We leave the "load the dtb" code in arm_load_kernel() -- this
is currently only used by the "direct kernel boot" path, but
this is a bug which we will fix shortly.

It is possible that the modifier state on keyup is different from the
modifier state on keydown. In that case the keycode lookup can end up
with different keys in case multiple keysym -> keycode mappings exist,
because it picks the mapping depending on modifier state.
To fix that change the lookup logic for keyup events. Instead of
looking at the modifier state check the key state and prefer a keycodes
where the key is in "down" state right now.

Now that most user interfaces are using QKeyCodes it is easier to have
common keyboard code useable by all user interfaces.
This patch adds helper code to track the state of all keyboard keys,
using a bitmap indexed by QKeyCode. Modifier state is tracked too,
as separate bitmap. That makes checking modifier state easier.
Likewise we can easily apply special handling for capslock & numlock
(toggles on keypress) and ctrl + shift (we have two keys for that).

Signed-off-by: Eric Blake <eblake@redhat.com>
The existing qemu-nbd --partition code claims to handle logical
partitions up to 8, since its introduction in 2008 (commit 7a5ca86).
However, the implementation is bogus (actual MBR logical partitions
form a sort of linked list, with one partition per extended table
entry, rather than four logical partitions in a single extended
table), making the code unlikely to work for anything beyond -P5 on
actual guest images. What's more, the code does not support GPT
partitions, which are becoming more popular, and maintaining device
subsetting in both NBD and the raw device is unnecessary duplication
of effort (even if it is not too difficult).
Note that obtaining the offsets of a partition (MBR or GPT) can be
learned by using 'qemu-nbd -c /dev/nbd0 file.qcow2 && sfdisk --dump
/dev/nbd0', but by the time you've done that, you might as well
just mount /dev/nbd0p1 that the kernel creates for you instead of
bothering with qemu exporting a subset. Or, keeping to just
user-space code, use nbdkit's partition filter, which has already
known both GPT and primary MBR partitions for a while, and was
just recently enhanced to support arbitrary logical MBR parititions.
Start the clock on the deprecation cycle, with examples of how
to accomplish device subsetting without using -P.

The tests tries to let qemu server mode to process the connection
which turns out to be racy after commit 8258292e18 ("monitor: Remove
"x-oob", offer capability "oob" unconditionally"). This is because the
filter may try to mirror the packets before UNIX socket object is
ready (connected was set to true) from the view of qemu. In this case
the packet will be dropped silently.
Fixing this by passing pre-connected socket created by socketpair() to
qemu through fd.

There is a flaw in the xen-bus state model. To allow a frontend to re-
connect the backend state of an online XenDevice is transitioned from
Closed to InitWait, but this is currently done unilaterally which is
incorrect. The backend state should remain Closed until the frontend state
transitions to Initialising.
This patch removes the automatic backend state transition from
xen_device_backend_state_changed() and, instead, adds an extra check in
xen_device_frontend_state_changed() to determine whether a frontend is
trying to re-connect to a previously Closed XenDevice. Only if this is
found to be the case is the backend state transitioned from Closed to
InitWait. Note that this transition will be common amongst all XenDevice
classes and hence xen_device_frontend_state_changed() returns immediately
afterwards without calling into the XenDeviceClass frontend_changed()
method.
