KVM: Remove internal timer abstraction
kvm_timer_fn(), the sole inhabitant of timer.c, is only used by lapic.c. Move it there to make it easier to hack on it. struct kvm_timer is a thin wrapper around hrtimer, and only adds obfuscation. Move near its two users (with different names) to prepare for simplification. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
