cpu: Introduce CPUClass::synchronize_from_tb() for cpu_pc_from_tb()

Where no extra implementation is needed, fall back to CPUClass::set_pc().

linux-user: Move cpu_clone_regs() and cpu_set_tls() into linux-user

The functions cpu_clone_regs() and cpu_set_tls() are not purely CPU
related -- they are specific to the TLS ABI for a a particular OS.
Move them into the linux-user/ tree where they belong....

cpu: Move halted and interrupt_request fields to CPUState

Both fields are used in VMState, thus need to be moved together.
Explicitly zero them on reset since they were located before
breakpoints.

Pass PowerPCCPU to kvmppc_handle_halt().

cpu: Replace do_interrupt() by CPUClass::do_interrupt method

This removes a global per-target function and thus takes us one step
closer to compiling multiple targets into one executable.

It will also allow to override the interrupt handling for certain CPU...

target-unicore32: Mark as unmigratable

CPU_SAVE_VERSION 2 was bogus as both save and load would just throw a
hw_error(). Therefore we can without problems suppress registration of
"cpu_common" VMState by dropping CPU_SAVE_VERSION define and provide an
unmigratable "cpu" VMStateDescription for UniCore32CPU at device level...

cpus: Pass CPUState to [qemu_]cpu_has_work()

For target-mips also change the return type to bool.

Make include paths for cpu-qom.h consistent for alpha and unicore32.

target-unicore32: Drop UC32_CPUID macros

Any code that depends on a particular CPU type can now go through
callbacks on the QOM UniCore32CPUClass.

unicore32-softmmu: Make UniCore32 cpuid & exceptions correct and runable

This patch initializes the cpuid to exactly correct value because
linux kernel will check it.
In addition, the exception types are specified in proper situations.
Then it could make exceptions generated correctly and timely....

target-unicore32: Relicense to GPLv2+

Adopt the license text suggested by Guan Xue-tao (with a minor
simplification) for all target-unicore/ files except helper.c.

To helper.c Anthony Liguori contributed a qemu_malloc() -> g_malloc()
conversion, still pending IBM relicensing approval, so that remains...
