We used to have a huge hack where RBTools would do a bunch of stuff to

try to find the local repository, but then the client could replace the

entire repository info structure. In 3.0 we cleaned all this up to add

the update_from_remote method, which would let the client fetch

whatever data it needed. When we did this we kept the old methods around

with a deprecation warning because third party tools and scripts could

potentially still be calling them. This change finally removes the

methods.

Ran unit tests.
