changegroup: don't try to prune manifest nodes if not ellipses
In non-ellipses case, the number of manifest nodes can be very big, and finding
whether one of them can be pruned or not is very costly. For each node, we try
to find the rev and the linkrev, which is expensive.
Sending bit more manifest nodes seems better and much faster here. On our
internal repository, this saves around 5 seconds on `hg tracked --addinclude
<some_path>` on a narrow repo with ellipses disabled.

Set up an extension to make sure remotefilelog clientsetup() runs
unconditionally even if we have never used a local shallow repo.
This mimics behavior when using remotefilelog with chg. clientsetup() can be
triggered due to a shallow repo, and then the code can later interact with
non-shallow repositories.
$ cat > setupremotefilelog.py << EOF
> from mercurial import extensions
> def extsetup(ui):
> remotefilelog = extensions.find(b'remotefilelog')
> remotefilelog.onetimeclientsetup(ui)
> EOF
Set up the master repository to pull from.
$ hg init master
$ cd master
$ cat >> .hg/hgrc <<EOF
> [remotefilelog]
> server=True
> EOF
$ echo x > x
$ hg commit -qAm x
$ cd ..
$ hg clone ssh://user@dummy/master child -q
We should see the remotefilelog capability here, which advertises that
the server supports our custom getfiles method.
$ cd master
$ echo 'hello' | hg -R . serve --stdio | grep capa | identifyrflcaps
exp-remotefilelog-ssh-getfiles-1
x_rfl_getfile
x_rfl_getflogheads
$ echo 'capabilities' | hg -R . serve --stdio | identifyrflcaps ; echo
exp-remotefilelog-ssh-getfiles-1
x_rfl_getfile
x_rfl_getflogheads
Pull to the child repository. Use our custom setupremotefilelog extension
to ensure that remotefilelog.onetimeclientsetup() gets triggered. (Without
using chg it normally would not be run in this case since the local repository
is not shallow.)
