Add some tests of reference D/F conflicts (by which I mean the fact
that references like "refs/foo" and "refs/foo/bar" are not allowed to
coexist) in the context of reference transactions.
The test of creating two conflicting references in the same
transaction fails, leaving the transaction half-completed. This will
be fixed later in this patch series.
Please note that the error messages emitted in the case of conflicts
are not very user-friendly. In particular, when the conflicts involve
loose references, then the errors are reported as
error: there are still refs under 'refs/foo'
fatal: Cannot lock the ref 'refs/foo'.
or
error: unable to resolve reference refs/foo/bar: Not a directory
fatal: Cannot lock the ref 'refs/foo/bar'.
This is because lock_ref_sha1_basic() fails while trying to lock the
new reference, before it even gets to the is_refname_available()
check. This situation will also be improved later in this patch
series.
