The Dark Avengers are not considered an "official" Avengers team by the Avengers themselves. They had official government status at the time due to Norman Osborn, but you can believe that if there is a situation where Captain America needs to call on every Avenger ever (like they did at the start of the Busiek/Perez run), the call is NOT going to be going out to Bullseye, Norman Osborn, Mac Gargan, etc.
The Savage Avengers are also not an actual Avengers team--although a number of the characters who have appeared in it ARE actual Avengers. But that is a case of a book that has "Avengers" thrown in the title for sales purposes. In-story there is nothing connecting that team to the Avengers franchise; they are just groups that happen to include one or two actual Avengers in the cast so the "Avengers" name was slapped on the cover to boost sales. The same was true for A-FORCE and OCCUPY AVENGERS...although Red Wolf from OCCUPY was later granted official status after working with the Avengers in the "No Surrender" storyline.
The Avengers Unity Squad (the UNCANNY team) absolutely are an official Avengers team. That was the entire point -- the Avengers reaching out and embracing the mutant community (and later the Inhuman community as well) to try and do their part for promoting equality and tolerance within the Marvel Universe.
The new West Coast Avengers are a bit trickier. Its hard to say at this point whether the main Avengers would consider them 'official' members or not. Both Hawkeyes are official Avengers, which is a point in their favour. However, if you remove Clint the team suddenly looks more like a new Young Avengers which are more of a satellite team, like the Great Lakes Avengers.
