branchcache: skip entries that are topological heads in the on disk file In the majority of cases, topological heads are also branch heads. We have efficient way to get the topological heads and efficient way to retrieve their branch information. So there is little value in putting them in the branch cache file explicitly. On the contrary, writing them explicitly tend to create very large cache file that are inefficient to read and update. So the branch cache v3 format is no longer including them. This changeset focus on the format aspect and have no focus on the performance aspect. We will cover that later.

Check that the pull logger plugins logs pulls
=============================================

Enable the extension

  $ echo "[extensions]" >> $HGRCPATH
  $ echo "pull-logger = $TESTDIR/../contrib/pull_logger.py" >> $HGRCPATH


Check the format of the generated log entries, with a bunch of elements in the
common and heads set

Check the number of entries generated in the log when pulling from multiple
clients at the same time

  $ rm -f server/.hg/pull_log.jsonl
  $ for i in $($TESTDIR/seq.py 32); do
  >   hg clone ssh://user@dummy/server client_$i --rev 0
  > done > /dev/null
  $ for i in $($TESTDIR/seq.py 32); do
  >   hg -R client_$i pull --rev 1 &
  > done > /dev/null
  $ wait
  $ wc -l server/.hg/pull_log.jsonl
  \s*64 .* (re)


Test log rotation when reaching some size threshold

  $ cat >> $HGRCPATH << EOF

  > EOF

  $ rm -f server/.hg/pull_log.jsonl
  $ for i in $($TESTDIR/seq.py 10); do

  $ wc -l server/.hg/pull_log.jsonl
