[PATCH 4/4]: Xend interface for HVM S3
  - extend "xm trigger <domid> s3resume" to be able to S3 resume HVM domain.
  - when user issue "xm trigger" command for HVM domain, xend will use xc
    lib API to call XEN_DOMCTL_SENDTRIGGER_S3RESUME domctl hypercall.
  - add s3_suspended state for HVM domain

Note: S3 suspend is initiated from HVM guest itself and resumed from
xm trigger command. We also add a new HVM state: s3_suspended, so that
save/restore now could work with a s3_suspended domain.
