rust-index: stop using C index

We still keep its wrapper implementation in `hg-cpython::cindex`,
because we might want to recreate ancestors handling objects using
it for the case of REVLOGV2.

Also, we still instantiate it (from Python code) and store it as
attribute, for the likes of `get_cindex` and the caller that
relies on it, but that is soon to be removed, too.

Bundle with partial content works

  $ hg -R server bundle --type gzip-v1 --base null -r 53245c60e682 partial.hg
  1 changesets found

We verify exact bundle content as an extra check against accidental future
changes. If this output changes, we could break old clients.

Again, we perform an extra check against bundle content changes. If this content
changes, clone bundles produced by new Mercurial versions may not be readable
by old clients.

Inline bundle
=============

Checking bundle retrieved over the wireprotocol

Feature works over SSH with inline bundle
-----------------------------------------

  $ mkdir server/.hg/bundle-cache/
  $ cp full.hg server/.hg/bundle-cache/
  $ echo "peer-bundle-cache://full.hg" > server/.hg/clonebundles.manifest
  $ hg clone -U ssh://user@dummy/server ssh-inline-clone

We don't use the clone bundle, but we do not crash either.

Pre-transmit Hook
-----------------

Hooks work with inline bundle

  $ cp server/.hg/hgrc server/.hg/hgrc-beforeinlinehooks
  $ echo "[hooks]" >> server/.hg/hgrc
  $ echo "pretransmit-inline-clone-bundle=echo foo" >> server/.hg/hgrc

Hooks can make an inline bundle fail

  $ cp server/.hg/hgrc-beforeinlinehooks server/.hg/hgrc
  $ echo "[hooks]" >> server/.hg/hgrc
  $ echo "pretransmit-inline-clone-bundle=echo bar && false" >> server/.hg/hgrc
  $ hg clone -U ssh://user@dummy/server ssh-inline-clone-hook-fail
  applying clone bundle from peer-bundle-cache://full.hg

  abort: stream ended unexpectedly (got 0 bytes, expected 1)

Testing a clone bundles that involves revlog splitting (issue6811)
==================================================================

  $ cat >> $HGRCPATH << EOF
  > [format]
  > revlog-compression=none
  > use-persistent-nodemap=no
  > EOF

  $ hg init server-revlog-split/
  $ cd server-revlog-split
  $ cat >> .hg/hgrc << EOF
  > [extensions]
  > clonebundles =
  > EOF
  $ echo foo > A
  $ hg add A
  $ hg commit -m 'initial commit'
IMPORTANT: the revlogs must not be split
  $ ls -1 .hg/store/00manifest.*
  .hg/store/00manifest.i
  $ ls -1 .hg/store/data/_a.*
  .hg/store/data/_a.i

do big enough update to split the revlogs

  $ $TESTDIR/seq.py 100000 > A
  $ mkdir foo
  $ cd foo
  $ touch `$TESTDIR/seq.py 10000`
  $ cd ..
  $ hg add -q foo
  $ hg commit -m 'split the manifest and one filelog'

IMPORTANT: now the revlogs must be split
  $ ls -1 .hg/store/00manifest.*
  .hg/store/00manifest.d
  .hg/store/00manifest.i
  $ ls -1 .hg/store/data/_a.*
  .hg/store/data/_a.d
  .hg/store/data/_a.i

Add an extra commit on top of that

  $ echo foo >> A
  $ hg commit -m 'one extra commit'

  $ cd ..

Do a bundle that contains the split, but not the update

  $ hg bundle --exact --rev '::(default~1)' -R server-revlog-split/ --type gzip-v2 split-test.hg
  2 changesets found

  $ cat > server-revlog-split/.hg/clonebundles.manifest << EOF
  > http://localhost:$HGPORT1/split-test.hg BUNDLESPEC=gzip-v2
  > EOF

start the necessary server

  $ "$PYTHON" $TESTDIR/dumbhttp.py -p $HGPORT1 --pid http.pid
  $ cat http.pid >> $DAEMON_PIDS
  $ hg -R server-revlog-split serve -d -p $HGPORT --pid-file hg.pid --accesslog access.log
  $ cat hg.pid >> $DAEMON_PIDS

Check that clone works fine
===========================

Here, the initial clone will trigger a revlog split (which is a bit clowny it
itself, but whatever). The split revlogs will see additionnal data added to
them in the subsequent pull. This should not be a problem

manifest should work

  $ hg  files -r tip | wc -l
  \s*10001 (re)

file content should work

  $ hg  cat -r tip A | wc -l
