Thanks for working on this. With the exception of the final patch, this
all seems pretty sane to me from a quick look.

There is one thing that your test patches made me wonder. When we have
to make an exception to a test (i.e., that doesn't work under v2), you
do it by unsetting GIT_TEST_PROTOCOL_VERSION in the environment. That
means we'll actually run the test, but not with the version that the
caller specified.

I wonder if it would be more obvious what's going on if we instead had a
prereq like:

  test_expect_success !PROTO_V2 'ls-remote --symref' '
     ...
  '

and just skipped those tests entirely (and in a way that appears in the
TAP output).

I think it would also future-proof us a bit for v2 becoming the default
(i.e., when GIT_TEST_PROTOCOL_VERSION being blank does mean "use v2").

I dunno. It probably doesn't matter all that much, so it may not be
worth going back and changing at this point. Just a thought.
