* LongVersion nIni may be causing the test thread death. Pausing OpenSimulator during startup causes a nIni error that makes debugging startup operations difficult for users. It might be because when it's in pause mode, something else reads from the nini config passed? If it is, it might not be fixable.. however, if it's concurrency that causes nini death it would make sense to give each section of the tests a new IConfigSource so that they don't read from the same configsource at the same time.
This may break a lot of things, but it needs to go in. It was tested in standalone and the UCI grid, but it needs a lot more testing.
Known problems:
* HG asset transfers are borked for now
* missing texture is missing
* 3 unit tests commented out for now
* Now, the 144 unit tests takes roughly as long time to run (16s on my laptop) that the 10 long running takes. The database tests takes forever.
* Feel free to run the unit tests as you code, and the rest before commit.
* This moves authentication from the client thread (where failure was difficult to detect) to the particular thread handling that packet
* I've kept the authentication outside of the crucial clientCircuits lock (though any delay here is probably swamped by the other delays associated with login)
* Also added more to the unit test to ensure this doesn't regress
* This checks that a client circuit is established when the udp server is given a use client circuit code packet
* And checks that other circuit codes do not exist
