[PATCH 0/2] Last big GIT_TEST_PROTOCOL_VERSION=2 fix, hopefully

This is built on master+jt/test-protocol-version, but should apply cleanly to master.

After [1] and this patch set, there is only one more small thing to fix or mark GIT_TEST_PROTOCOL_VERSION=0 at master+jt/test-protocol-version.

This is very similar to [2], which was neither reviewed nor merged, perhaps because I had another patch [3] that I declared to supersede [2] and that was merged as bd0b42aed3 ("fetch-pack: do not take shallow lock unnecessarily", 2019-01-10). But it turns out that [3] was not enough to make all tests pass with GIT_TEST_PROTOCOL_VERSION=2, hence this patch set.

  fetch-pack: call prepare_shallow_info only if v0
  fetch-pack: respect --no-update-shallow in v2
