unstable-list: add the basic about orphan changesets

The goal of this part is to quickly explain orphan and main idea behind its
resolution.

test discovery avoid exchanging known markers

  $ hg push
  pushing to ssh://user@dummy/server
  searching for changes
  no changes found

  $ hg -R ../other pull
  pulling from ssh://user@dummy/server
  searching for changes
  no changes found

test discovery can be disabled

  $ hg push --config experimental.evolution.obsdiscovery=no
  pushing to ssh://user@dummy/server
  searching for changes
  (skipping discovery of obsolescence markers, will exchange everything)
  (controled by 'experimental.evolution.obsdiscovery' configuration)
  no changes found
  remote: obsmarker-exchange: 274 bytes received
  [1]
  $ hg -R ../other pull --config experimental.evolution.obsdiscovery=no
  pulling from ssh://user@dummy/server
  searching for changes
  no changes found
  (skipping discovery of obsolescence markers, will exchange everything)
  (controled by 'experimental.evolution.obsdiscovery' configuration)
  obsmarker-exchange: 274 bytes received

  $ cd ..

And disable it server side too:

  $ hg serve -R server -n test -p $HGPORT -d --pid-file=hg.pid -A access.log -E errors.log  --config experimental.evolution.obsdiscovery=no
  $ cat hg.pid >> $DAEMON_PIDS

  $ hg debugcapabilities http://localhost:$HGPORT | grep _evoext
    _evoext_getbundle_obscommon
    _evoext_obshashrange_v1

Check we cannot use pushkey for marker exchange anymore

  $ hg debugpushkey http://localhost:$HGPORT/ obsolete
  abort: HTTP Error 410: won't exchange obsmarkers through pushkey
  [255]
  $ cat errors.log
  $ hg debugpushkey ssh://user@dummy/server obsolete
  remote: abort: won't exchange obsmarkers through pushkey
  remote: (upgrade your client or server to use the bundle2 protocol)
  abort: unexpected response: empty string
  [255]

(do some extra pulling to be sure)

  $ hg -R client pull http://localhost:$HGPORT/
  pulling from http://localhost:$HGPORT/
  searching for changes
  no changes found

  $ hg -R client pull http://localhost:$HGPORT/ --config experimental.evolution=createmarkers
  pulling from http://localhost:$HGPORT/
  searching for changes
  no changes found

  $ hg -R client pull http://localhost:$HGPORT/ --config experimental.evolution=createmarkers --config extensions.evolve='!'
  pulling from http://localhost:$HGPORT/
  searching for changes
  no changes found

But we do let it goes fine on repository with exchange disabled:

  $ $RUNTESTDIR/killdaemons.py $DAEMON_PIDS
  $ hg serve -R server -n test -p $HGPORT -d --pid-file=hg.pid -A access.log -E errors.log  --config experimental.evolution='!'
  $ cat hg.pid >> $DAEMON_PIDS
  $ hg debugpushkey http://localhost:$HGPORT/ obsolete
