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
GPLv2 for now.

By relicensing all possible parts now, we avoid having to formally
relicense new, e.g., QOM code.

Scripted conversion:

  done

All occurrences of CPUArchState are expected to be replaced by QOM CPUState,
once all targets are QOM'ified and common fields have been extracted.

This aids in refactoring CPUState by adopting the common naming scheme.

Parameter is_softmmu (and its evil mutant twin brother is_softmuu)
is not used in cpu_*_handle_mmu_fault() functions, remove them
and adjust callers.

Move functions cpu_has_work() and cpu_pc_from_tb() from exec.h to cpu.h. This is
needed by later patches.
