Remove deprecated features from Djblets 2.0.
Review Request #10616 — Created July 3, 2019 and submitted
We had a large number of classes, functions, modules, and parameters
that have been marked as deprecated, some for a very long time. This
change removes all these deprecated pieces of code.
Some parts of the codebase were still making use of the deprecated
functionality, so they've been updated accordingly.
There's a couple of template tag libraries that weren't themselves
marked as deprecated. These are the
template tag libraries. They're now empty, but we're keeping them around
Unit tests pass.
