bundle: do no check the changegroup version if no changegroup is included

We don't need to check the compatibility of something we will not use.

In practice this was getting in the was of `streamv2` bundles on a narrow
repository as the 'cg.version=02' value was rejected by this checks.

Initial cloning if needed
-------------------------

  $ hg admin::chainsaw-update --dest repo --rev default --source ./src

Test lock breacking capabilities
--------------------------------

Demonstrate lock-breaking capabilities with locks that regular Mercurial
operation would not break, because the hostnames registered in locks differ
from the current hostname (happens a lot with succesive containers):

  $ ln -s invalid.host.test/effffffc:171814 .hg/store/lock
  $ ln -s invalid.host.test/effffffc:171814 .hg/wlock
  $ hg debuglock
  lock:  (.*?), process 171814, host invalid.host.test/effffffc \((\d+)s\) (re)
  wlock: (.*?), process 171814, host invalid.host.test/effffffc \((\d+)s\) (re)
  [2]

  $ hg admin::chainsaw-update --no-purge-ignored --dest . --rev default --source ../src
  loaded repository at "."
  had to break store lock
  had to break working copy lock
  recovering after interrupted transaction, if any
  no interrupted transaction available
  pulling from ../src
  updating to revision 'default'
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  chainsaw-update to revision 'default' for repository at '$TESTTMP/repo' done

Test file purging capabilities
------------------------------

Let's also add local modifications (tracked and untracked) to demonstrate the
purging.

  $ echo untracked > bar
  $ echo modified > foo
  $ hg status -A
  M foo
  ? bar
  C root

  $ echo 2 > ../src/foo
  $ hg -R ../src commit -mB_1
  $ hg admin::chainsaw-update --dest . --rev default --source ../src -q
  no interrupted transaction available
  $ hg log -G

  $ hg status -A
  C foo
  C root
  $ cat foo
  2

Now behaviour with respect to ignored files: they are not purged if
the --no-purge-ignored flag is passed, but they are purged by default

  $ echo bar > .hgignore
  $ hg ci -Aqm hgignore
  $ echo ignored > bar
  $ hg status --all
  I bar
  C .hgignore
  C foo
  C root

  $ hg admin::chainsaw-update --no-purge-ignored --dest . --rev default --source ../src -q
  no interrupted transaction available
  $ hg status --all
  I bar
  C .hgignore
  C foo
  C root
  $ cat bar
  ignored

  $ hg admin::chainsaw-update --dest . --rev default --source ../src -q
  no interrupted transaction available
  $ hg status --all
  C .hgignore
  C foo
  C root
  $ test -f bar
  [1]

test --minimal-initial-cloning variant
--------------------------------------

With `--minimal-initial-cloning`, there is no "requesting all changes"
message. Hence clone bundles would be bypassed (TODO test both cases
# with an actual clone-bundle)

  $ cd ..
  $ hg admin::chainsaw-update --dest repo2 --rev default --source src --initial-clone-minimal
  no such directory: "repo2"
  creating repository at "repo2"
  recovering after interrupted transaction, if any
  no interrupted transaction available
  pulling from src
  updating to revision 'default'
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  chainsaw-update to revision 'default' for repository at '$TESTTMP/repo2' done

  $ cd repo2
  $ hg log -G
