    pam: update code
    
    Eliminate another md->v1_st reference in IKEv2 code.
    
    - replace #define AUTH_HAVE_PAM with #define USE_PAM_AUTH
    - wrap #include "pam_auth.h" in #ifdef USE_PAM_AUTH
    - taint "pam_auth.h" - error when included and not USE_PAM_AUTH
    - name everything pam_auth_*()
    - change fork callback to return stf_status; and pass that on to
      complete_v*_state_transition() making it IKEv2 friendly
      (still much duplication between thread and fork callbacks, sigh)
    - drop make variable USE_XAUTHPAM - 4.4 has been released
