Originally, there is cross-references between instr_emul.h and instr_emul_wrapper.h.
User must include both of them when calling instruction emulation functions. This
will raise up some confusion and inconvenience.
So we rearrange the logic of instruction emulation code as following:
- External API -- defined in instr_emul.h
* decode_instruction(struct vcpu *vcpu)
* emulate_instruction(struct vcpu *vcpu)
- Make all other functions as static in instr_emul.c
- Remove instr_emul_wrapper.c/h
No functional change.
