rebase: use obsolete.isenabled() to check for experimental.allowdivergence

Now that obsolete.isenabled() can also check if divergence is allowed, let's
use it for consistency. Other experimental.evolution options are already
checked via this function.

Requesting parents works

  $ sendhttpv2peer << EOF

Requesting revision data works
(haveparents defaults to False, so fulltext is emitted)

  $ sendhttpv2peer << EOF

      b'node': b'\n\x862\x1f\x13y\xd1\xa9\xec\xd0W\x9a"\x97z\xf7\xa5\xac\xaf\x11'

haveparents=False should be same as above

      b'node': b'\n\x862\x1f\x13y\xd1\xa9\xec\xd0W\x9a"\x97z\xf7\xa5\xac\xaf\x11'

  ]

haveparents=True should emit a delta

  $ sendhttpv2peer << EOF

    b'\x00\x00\x00Q\x00\x00\x00Q\x00\x00\x00\x03a1\n'

Requesting multiple revisions works
