conncheck: test inbound stun address on the candidate base address
When receiving an stun packet on a socket, and looking for the matching local candidate, normally it doesn't make a difference to test the address or the base address. Because a pair cannot have a local candidate of type srv-rflx, where there would be a difference, the local candidate obtained will be part of a pair of the conncheck list. Except for the case of a pairs with tcp-act local candidate, where the addr has a port number of zero (tcp-act socket before connect), and the socket of the stun packet has a non-null port number (tcp-act socket after connect), corresponding to the base address of another peer-reflexive tcp-act local candidate, previously discoverd. The selection of the local candidate concerned by an inbound stun request happens when early incoming checks are processed, and when inbound stun packets are normally received during the conncheck. This commit complete commit e6a19418 (for early incoming checks) in the normal inbound stun packets code path, where is similar modification is needed.
