revlog: add a callback "tracking" duplicate node addition
If a changegroup contains node already added to the repository, they will be
skipped. Skipping them is the right behavior (we don't need to store things
twice), but it can hide some information to the code doing the unbundle (eg:
shelve looking for the tip of the bundle).
The first step to improve this situation is to add a low level callback. We do
not need this tracking on all revlog, so actual tracking will be added in the
next changeset.
Tests discovery against servers without getbundle support:
$ cat >> $HGRCPATH <<EOF
> [ui]
> logtemplate="{rev} {node|short}: {desc} {branches}\n"
> EOF
$ cp $HGRCPATH $HGRCPATH-withcap
$ CAP="getbundle known changegroupsubset bundle2"
$ . "$TESTDIR/notcapable"
$ cp $HGRCPATH $HGRCPATH-nocap
$ cp $HGRCPATH-withcap $HGRCPATH
Prep for test server without branchmap support
$ CAP="branchmap"
$ . "$TESTDIR/notcapable"
$ cp $HGRCPATH $HGRCPATH-nocap-branchmap
$ cp $HGRCPATH-withcap $HGRCPATH
Setup HTTP server control:

> echo 'allow_push = *' >> $1/.hg/hgrc
> cp $HGRCPATH-nocap $HGRCPATH
> hg serve -R $1 -p $HGPORT -d --pid-file=hg.pid -E errors.log
> cat hg.pid >> $DAEMON_PIDS
> }
$ tstop() {
