branchcache-v3: use more explicit header line

The key-value approach is clearer and gives more rooms to have the format evolve
in a clear way. It also provides extension (like topic) simpler way to extend
the validation scheme.

This is just a small evolution, the V3 format is still a work in progress.

  $ hg init test
  $ cd test
  $ hg debugbuilddag '+2'
  $ hg phase --public 0

  $ hg serve -p $HGPORT -d --pid-file=hg.pid -E errors.log
  $ cat hg.pid >> $DAEMON_PIDS
  $ cd ..
  $ hg init test2
  $ cd test2
  $ hg incoming http://foo:xyzzy@localhost:$HGPORT/ -T '{desc}\n'
  comparing with http://foo:***@localhost:$HGPORT/
  r0
  r1
  $ killdaemons.py

  $ cd ..
  $ hg -R test --config server.view=immutable serve -p $HGPORT -d --pid-file=hg.pid -E errors.log
  $ cat hg.pid >> $DAEMON_PIDS
  $ hg -R test2 incoming http://foo:xyzzy@localhost:$HGPORT/ -T '{desc}\n'
  comparing with http://foo:***@localhost:$HGPORT/
  r0

Check same result using `experimental.extra-filter-revs`

  $ hg -R test --config experimental.extra-filter-revs='not public()' serve -p $HGPORT1 -d --pid-file=hg2.pid -E errors.log
  $ cat hg2.pid >> $DAEMON_PIDS
  $ hg -R test2 incoming http://foo:xyzzy@localhost:$HGPORT1/
  comparing with http://foo:***@localhost:$HGPORT1/

cleanup

  $ cat errors.log
  $ killdaemons.py

Check the behavior is other filtered revision exists
----------------------------------------------------

add more content and complexity to the repository too

  $ hg -R test debugbuilddag '+6:branchpoint.:left+4*branchpoint.:right+5' --from-existing
  $ hg -R test phase --public 'desc("re:^r11$")'
  $ hg -R test phase --secret --force 'desc("re:^r9$")'
  $ hg -R test log -G -T '{desc} {phase}\n'
