x86: fix migration from pre-version 12
On KVM, the KVM_SET_XSAVE would be executed with a 0 xstate_bv,
and not restore anything.
Since FP and SSE data are always valid, set them in xstate_bv at reset
time. In fact, that value is the same that KVM_GET_XSAVE returns on
pre-XSAVE hosts.

kvmvapic: Prevent reading beyond the end of guest RAM
rom_state_paddr is guest provided (caller address of outw(VAPIC_PORT) +
writen 16-bit value) and can be influenced to point beyond the end of
the host memory backing the guest's RAM. Make sure we do not use this
pointer to actually read beyond the limits.
Reading arbitrary guest bytes is harmless, the guest kernel has to
manage access to this I/O port anyway.

Delete an unnecessary dependency for cocoa.o; we already have
a general rule that tells Make that we can build a .o file
from a .m source using an ObjC compiler, so this specific
rule is unnecessary. Further, it is using the dubious construct
"$(SRC_PATH)/$(obj)" to get at the source directory, which will
break when $(obj) is redefined as part of the preparation for
per-object library support.

Log Message:
-----------
Fix VNC SASL authentication when using a QXL device
ui/vnc.c:vnc_display_open() and spice-server/server/reds.c:do_spice_init()
are both calling sasl_server_init(). If spice_server_set_sasl_appname()
hasn't been called, spice-server will call it with "spice" as an appname,
causing cyrus-sasl to try to use a /etc/sasl2/spice.conf config file rather
than the /etc/sasl2/qemu.conf file that QEMU uses.
When using -spice sasl on the command line, QEMU properly calls
spice_server_set_sasl_appname() to set the SASL appname as "qemu",
but when using a QXL device without using SPICE, spice_server_init()
is called from qemu_spice_add_interface() without setting the appname
to "qemu", which then causes the VNC code to try to use spice.conf
instead of qemu.conf.

spice: fix multihead support
This patch fixes spice display initialization to handle
multihead properly.
spice-core now keeps track of which QemuConsole has a spice
display channel attached to it and which has not. It also
manages display channel ids.
spice-display looks at all QemuConsoles and will pick up any
graphic console not yet bound to a spice channel (which in practice
are all non-qxl graphic devices).
Result is that
(a) you'll get a spice client window for each graphical device
now (first only without this patch), and
(b) mixing qxl and non-qxl vga cards works properly.

qemu-thread: add QemuEvent
This emulates Win32 manual-reset events using futexes or conditional
variables. Typical ways to use them are with multi-producer,
single-consumer data structures, to test for a complex condition whose
elements come from different threads:
for (;;) {
qemu_event_reset(ev);
... test complex condition ...
if (condition is true) {
break;
}
qemu_event_wait(ev);
}
Or more efficiently (but with some duplication):
... evaluate condition ...
while (!condition) {
qemu_event_reset(ev);
... evaluate condition ...
if (!condition) {
qemu_event_wait(ev);
... evaluate condition ...
}
}
QemuEvent provides a very fast userspace path in the common case when
no other thread is waiting, or the event is not changing state.

Note, qemu_clock_enable(foo,false) can _not_ be called from timer's cb.
Also, the callers of qemu_clock_enable() should be protected by the BQL.

timer: add timer_mod_anticipate and timer_mod_anticipate_ns
These let a user anticipate the deadline of a timer, atomically with
other sites that call the function. This helps avoiding complicated
lock hierarchies.

icount: reorganize icount_warp_rt
To prepare for future code changes, move the increment of qemu_icount_bias
outside the "if" statement.
Also, hoist outside the if the check for timers that expired due to the
"warping". The check is redundant when !runstate_is_running(), but
doing it this way helps because the code that increments qemu_icount_bias
will be a critical section.

icount: prepare the code for future races in calling qemu_clock_warp
Computing the deadline of all vm_clocks is somewhat expensive and calls
out to qemu-timer.c; two reasons not to do it in the seqlock's write-side
critical section. This however opens the door for races in setting and
reading vm_clock_warp_start.
To plug them, we need to cover the case where a new deadline slips in
between the call to qemu_clock_deadline_ns_all and the actual modification
of the icount_warp_timer. Restrict changes to vm_clock_warp_start and
the icount_warp_timer's expiration time, to only move them back (which
would simply cause an early wakeup).
If a vm_clock timer is cancelled while CPUs are idle, this might cause the
icount_warp_timer to fire unnecessarily. This is not a problem, after it
fires the timer becomes inactive and the next call to timer_mod_anticipate
will be precise.
In addition to this, we must deactivate the icount_warp_timer _before_
checking whether CPUs are idle. This way, if the "last" CPU becomes idle
during the call to timer_del we will still set up the icount_warp_timer.
