Use Tor Browser's integrated `AF_LOCAL` support on alpha.
The tbb_stub.so
used by sandboxed-tor-browser
currently overloads socket()
and connect()
to force Firefox into using an AF_LOCAL socket for the control and socks ports.
Once the stable release series has first class support for AF_LOCAL, the surrogate and stub should be changed to use those over the hack to reduce the amount of code in the stub.
Note: The stub has other duties and likely will be impossible to eliminate entirely, but the smaller the stub is the better.
