revlog: add a `canonical_index_file` attribute on inner revlog

This is currently the same and the index_file but it will become more complex
when we start doing delayed write.

  $ hg commit -m 'c_modify_c - modify a.txt'

Modify and rename a.txt to b.txt

  $ hg up -r "desc('c_base_c')"
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ sed -e 's/6/bar/' a.txt > a.tmp; mv a.tmp a.txt

Merge each branch

  $ hg merge -r "desc('c_modify_c')"

the history was altered

in theory p1/p2 order does not matter but in practice p1 == nullid is used as a
marker that some metadata are present and should be fetched.

Test the command that fixes the issue
=====================================

Restore a broken repository with multiple broken revisions and a filename that
would get encoded to test the `report` options.
It's a tarball because unbundle might magically fix the issue later.

  $ cd ..
  $ mkdir repo-to-fix
  $ cd repo-to-fix
  $ tar -xf - < "$TESTDIR"/bundles/issue6528.tar

Check that the issue is present
(It is currently not present with rhg but will be when optimizations are added
to resolve ambiguous files at the end of status without reading their content
if the size differs, and reading the expected size without resolving filelog
deltas where possible.)
