target-i386: Enabling IA32_TSC_ADJUST for QEMU KVM guest VMs

CPUID.7.0.EBX[1]=1 indicates IA32_TSC_ADJUST MSR 0x3b is supported

Basic design is to emulate the MSR by allowing reads and writes to the
hypervisor vcpu specific locations to store the value of the emulated MSRs.
In this way the IA32_TSC_ADJUST value will be included in all reads to
the TSC MSR whether through rdmsr or rdtsc.

As this is a new MSR that the guest may access and modify its value needs
to be migrated along with the other MRSs. The changes here are specifically
for recognizing when IA32_TSC_ADJUST is enabled in CPUID and code added
for migrating its value.

target-alpha: Avoid leaking the alarm timer over reset

Move the timer from CPUAlphaState to AlphaCPU to avoid the pointer being
zero'ed once we implement reset. Would cause a segfault in
sys_helper.c:helper_set_alarm().

This also simplifies timer initialization in Typhoon.

target-alpha: Turn CPU definitions into subclasses

Make TYPE_ALPHA_CPU abstract and add types <name>-alpha-cpu.
Use type inheritence, and turn "2*" models into aliases.

Move cpu_alpha_init() to cpu.c and split out CPU realization.
Default to creating type "ev67-alpha-cpu" as before.

qdev-properties.c: Separate core from the code used only by qemu-system-*

This separates the qdev properties code in two parts:
 - qdev-properties.c, that contains most of the qdev properties code;
 - qdev-properties-system.c for code specific for qemu-system-*,
   containing:
   - Property types: drive, chr, netdev, vlan, that depend on code that
     won't be included on *-user
   - qemu_add_globals(), that depends on qemu-config.o.

This change should help on two things:
 - Allowing DeviceState to be used by *-user without pulling
   dependencies that are specific for qemu-system-*;
 - Writing qdev unit tests without pulling too many dependencies.

The copyright/license of qdev-properties.c isn't explicitly stated at
the file, so add a simple copyright/license header pointing to the
commit ID of the original file.
