the build.
Historical note: internal was initially the only back-end; then support for
libtestdriver1 was added gradually.
Question: if/when we have complete libtestdriver1 support, do we still need
internal? Thoughts:
- It's useful to have builds with both a driver and the built-in, in
order to test fallback to built-in, but this could be achieved with
libtestdriver1 too.
- Performance might be better with internal though?
- The instrumentation works the same with both back-ends.
libtestdriver1 was added gradually. Support for libtestdriver1 is now complete
(see following sub-sections), so we could remove internal now. Note it's
useful to have builds with both a driver and the built-in, in order to test
fallback to built-in, which is currently done only with internal, but this can
be achieved with libtestdriver1 just as well.
Note: our test drivers tend to provide all possible entry points (with a few
exceptions that may not be intentional, see the next sections). However, in
