changegroup: populate _clnodetorev as part of changelog linknode lookup

The thing that matters is that self._clnodetorev is populated with
changesets that are being sent. Back when this code was in an
extension, it wasn't possible to monkeypatch the changelog lookup
function. Now that the code is in core, we can move this code to
where it logically belongs.

#require serve

  $ hg init server
  $ hg serve -R server -p $HGPORT -d --pid-file=hg1.pid -E ../error.log
  $ cat hg1.pid >> $DAEMON_PIDS

Check basic fetching

  $ hg debugdownload "http://localhost:$HGPORT/?cmd=lookup&key=tip"
  1 0000000000000000000000000000000000000000
  $ hg debugdownload  -o null.txt "http://localhost:$HGPORT/?cmd=lookup&key=null"
  $ cat null.txt
  1 0000000000000000000000000000000000000000

Check the request is made from the usual Mercurial logic
(rev details, give different content if the request has a Mercurial user agent)

  $ get-with-headers.py --headeronly "localhost:$HGPORT" "rev/tip" content-type
  200 Script output follows
  content-type: text/html; charset=ascii
  $ hg debugdownload "http://localhost:$HGPORT/rev/tip"
  
  # HG changeset patch
  # User 
  # Date 0 0
  # Node ID 0000000000000000000000000000000000000000
  
  
  
  

Check other kind of compatible url

  $ hg debugdownload ./null.txt
  1 0000000000000000000000000000000000000000
