Summary:                    Transfer to parking lot replies '202 Accepted'
rather than '480 Temporarily Unavailable' when lot is full
Description: 
When using sip refer to blind transfer to the parking lot, asterisk always
responds '202 Accepted'. When the parking lot is full it should instead
respond '480 Temporarily Unavailable'.

I see that a park_space_reserve function was fairly recently added to
features.c. At the moment it is used only for dtmf initiated transfers to
parking lots but there is no reason it cannot also be used in chan_sip.c
for the same purpose. For example (in pseudocode):

sip_park_thread() {
 pu = ast_park_space_reserve()
 if (!pu) { transmit_response("480 Temporarily Unavailable"); }
 else {
  ast_do_masquerade()
  res = ast_park_call(pu); 
 }
}
