(L)APIC is a part of cpu [1] so move APIC initialization inside of
x86_cpu object. Since cpu_model and override flags currently specify
whether APIC should be created or not, APIC creation&initialization is
moved into x86_cpu_apic_init() which is called from x86_cpu_realize().
[1] - all x86 cpus have integrated APIC if we overlook existence of i486,
and it's more convenient to model after majority of them.

Implement byte/halfword read and write for the NVIC SCB_SHPRx
(System Handler Priority Registers). Do this by removing SHPR word access
from nvic_readl/writel and adding common code to hande all access
sizes in nvic_sysreg_read/write.
Because the "nvic_state *s" variable now needs to be declared in
nvic_sysreg_read/write, the "void *opaque" parameter of
nvic_readl/writel is changed to "nvic_state *s".

This code adds console support by implementing SCLP's ASCII Console
Data event. This is the same console as LPARs ASCII console or z/VMs
sysascii.
The console can be specified manually with something like
-chardev stdio,id=charconsole0 -device sclpconsole,chardev=charconsole0,id=console0
Newer kernels will autodetect that console and prefer that over virtio
console.
When data is received from the character layer it creates a service
interrupt to trigger a Read Event Data command from the guest that will
pick up the received character byte-stream.
When characters are echo'ed by the linux guest a Write Event Data occurs
which is forwarded by the Event Facility to the console that supports
a corresponding mask value.
Console resizing is not supported.
The character layer byte-stream is buffered using a fixed size iov
buffer.

This implements the sclp signal quiesce event via the SCLP Event
Facility.
This allows to gracefully shutdown a guest by using system_powerdown
notifiers. It creates a service interrupt that will trigger a
Read Event Data command from the guest. This code will then add an
event that is interpreted by linux guests as ctrl-alt-del.

Several SCLP features are considered to be events. Those events don't
provide SCLP commands on their own, instead they are all based on
Read Event Data, Write Event Data, Write Event Mask and the service
interrupt. Follow-on patches will provide SCLP's Signal Quiesce (via
system_powerdown) and the ASCII console.
Further down the road the sclp line mode console and configuration
change events (e.g. cpu hotplug) can be implemented.
