Test that accessing to invalid changelog cache is avoided at
subsequent operations even if repo object is reused even after failure
of transaction (see 0a7610758c42 also)

"hg log" after failure of transaction is needed to detect invalid
cache in repoview: this can't detect by "hg verify" only.

Combination of "finalization" and "empty-ness of changelog" (2 x 2 =
4) are tested, because '00changelog.i' are differently changed in each
cases.

Test symlink traversal over cached audited paths:
-------------------------------------------------

#if symlink

set up symlink hell

  $ mkdir merge-symlink-out
  $ hg init merge-symlink
  $ cd merge-symlink
  $ touch base
  $ hg commit -qAm base
  $ ln -s ../merge-symlink-out a
  $ hg commit -qAm 'symlink a -> ../merge-symlink-out'
  $ hg up -q 0
  $ mkdir a
  $ touch a/poisoned
  $ hg commit -qAm 'file a/poisoned'
  $ hg log -G -T '{rev}: {desc}\n'
  @  2: file a/poisoned
  |
  | o  1: symlink a -> ../merge-symlink-out
  |/
  o  0: base


try trivial merge after update: cache of audited paths should be discarded,
and the merge should fail (issue5628)

  $ hg up -q null
  >>> from hgclient import check, readchannel, runcommand
  >>> @check
  ... def merge(server):

  ...     runcommand(server, [b'merge', b'2'])
  *** runcommand up -qC 2
  *** runcommand up -qC 1
  *** runcommand merge 2
  abort: path 'a/poisoned' traverses symbolic link 'a'
   [255]
  $ ls ../merge-symlink-out

cache of repo.auditor should be discarded, so matcher would never traverse
symlinks:

  $ hg up -qC 0
  $ touch ../merge-symlink-out/poisoned
  >>> from hgclient import check, readchannel, runcommand
  >>> @check
  ... def files(server):

  ...     # here 'a' is a symlink, so a/poisoned should be warned
  ...     runcommand(server, [b'files', b'a/poisoned'])
  *** runcommand up -qC 2
