sidedata: use revlogv2 requirement in the test helper

We are about to drop the requirement dedicated to sidedata (since revlogv2 will
support them unconditionally and previous version will not.).

To prepare this more we adapt the test code to not use that requirements.

#testcases tree flat-fncache flat-nofncache

Tests narrow stream clones

  $ . "$TESTDIR/narrow-library.sh"

#if tree
  $ cat << EOF >> $HGRCPATH
  > [experimental]
  > treemanifest = 1
  > EOF
#endif

#if flat-nofncache
  $ cat << EOF >> $HGRCPATH
  > [format]
  > usefncache = 0
  > EOF
#endif

Server setup

  $ hg init master
  $ cd master
  $ mkdir dir
  $ mkdir dir/src
  $ cd dir/src
  $ for x in `$TESTDIR/seq.py 20`; do echo $x > "F$x"; hg add "F$x"; hg commit -m "Commit src $x"; done

  $ cd ..
  $ mkdir tests
  $ cd tests
  $ for x in `$TESTDIR/seq.py 20`; do echo $x > "F$x"; hg add "F$x"; hg commit -m "Commit src $x"; done
  $ cd ../../..

Trying to stream clone when the server does not support it

  $ hg clone --narrow ssh://user@dummy/master narrow --noupdate --include "dir/src/F10" --stream
  streaming all changes
  remote: abort: server does not support narrow stream clones
  abort: pull failed on remote
  [100]

Enable stream clone on the server

  $ echo "[experimental]" >> master/.hg/hgrc
  $ echo "server.stream-narrow-clones=True" >> master/.hg/hgrc

Cloning a specific file when stream clone is supported

  $ hg clone --narrow ssh://user@dummy/master narrow --noupdate --include "dir/src/F10" --stream
  streaming all changes
  * files to transfer, * KB of data (glob)
  transferred * KB in * seconds (* */sec) (glob)

  $ cd narrow
  $ ls -A
  .hg
  $ hg tracked
  I path:dir/src/F10

Making sure we have the correct set of requirements

  $ cat .hg/requires
  dotencode (tree !)
  dotencode (flat-fncache !)
  fncache (tree !)
  fncache (flat-fncache !)
  generaldelta
  narrowhg-experimental
  persistent-nodemap (rust !)
  revlog-compression-zstd (zstd !)
  revlogv1
  sparserevlog
  store
  treemanifest (tree !)

Making sure store has the required files

  $ ls .hg/store/
  00changelog.i
  00manifest.i
  data
  fncache (tree !)
  fncache (flat-fncache !)
  meta (tree !)
  narrowspec
  undo
  undo.backupfiles
  undo.narrowspec
  undo.phaseroots

Checking that repository has all the required data and not broken

  $ hg verify
  checking changesets
  checking manifests
  checking directory manifests (tree !)
  crosschecking files in changesets and manifests
  checking files
  checked 40 changesets with 1 changes to 1 files
