Currently the vcpu_make_request and signal_event in vcpu_lock_instr_emulation
does not check whether target VCPU is up and running. This can cause
problems because when VCPU is created but not launched,
vcpu_make_request will not trigger wait_event on target VCPU, but
signal_event may still execute to reduce the counter.
This patch adds a check before vcpu_make_request and signal_event to
make sure the request and signal are issued after target VCPU is up.

Because the emulation code is for both split-lock and uc-lock,
rename splitlock.c/splitlock.h to lock_instr_emul.c/lock_instr_emul.h
