upgrade: implement partial upgrade for upgrading persistent-nodemap

Upgrading repositories to use persistent nodemap should be fast and easy as it
requires only two things:

1) Updating the requirements
2) Writing a persistent-nodemap on disk

For both of the steps above, we don't need to edit existing revlogs.

This patch makes upgrade only do the above mentioned two steps if we are
only upgarding to use persistent-nodemap feature.

Since `nodemap.persist_nodemap()` assumes that there exists a nodemap file for
the given revlog if we are trying to call it, this patch adds `force` argument
to create a file if does not exist which is true in our upgrade case.

The test changes demonstrate that we no longer write nodemap files for manifest
after upgrade which I think is desirable.

Create a repo and add some commits

  $ hg init mm
  $ cd mm
  $ echo "Test content" > testfile1
  $ hg add testfile1
  $ hg commit -m "First commit" -u "Proper <commit@m.c>"
  $ echo "Test content 2" > testfile2
  $ hg add testfile2
  $ hg commit -m "Second commit" -u "Commit Name 2 <commit2@m.c>"
  $ echo "Test content 3" > testfile3
  $ hg add testfile3
  $ hg commit -m "Third commit" -u "Commit Name 3 <commit3@m.c>"
  $ echo "Test content 4" > testfile4
  $ hg add testfile4
  $ hg commit -m "Fourth commit" -u "Commit Name 4 <commit4@m.c>"

Add a .mailmap file with each possible entry type plus comments
  $ cat > .mailmap << EOF
  > # Comment shouldn't break anything
  > <proper@m.c> <commit@m.c> # Should update email only
  > Proper Name 2 <commit2@m.c> # Should update name only
  > Proper Name 3 <proper@m.c> <commit3@m.c> # Should update name, email due to email
  > Proper Name 4 <proper@m.c> Commit Name 4 <commit4@m.c> # Should update name, email due to name, email
  > EOF
  $ hg add .mailmap
  $ hg commit -m "Add mailmap file" -u "Testuser <test123@m.c>"

Output of commits should be normal without filter
  $ hg log -T "{author}\n" -r "all()"
  Proper <commit@m.c>
  Commit Name 2 <commit2@m.c>
  Commit Name 3 <commit3@m.c>
  Commit Name 4 <commit4@m.c>
  Testuser <test123@m.c>

Output of commits with filter shows their mailmap values
  $ hg log -T "{mailmap(author)}\n" -r "all()"
  Proper <proper@m.c>
  Proper Name 2 <commit2@m.c>
  Proper Name 3 <proper@m.c>
  Proper Name 4 <proper@m.c>
  Testuser <test123@m.c>

Add new mailmap entry for testuser
  $ cat >> .mailmap << EOF
  > <newmmentry@m.c> <test123@m.c>
  > EOF

Output of commits with filter shows their updated mailmap values
  $ hg log -T "{mailmap(author)}\n" -r "all()"
  Proper <proper@m.c>
  Proper Name 2 <commit2@m.c>
  Proper Name 3 <proper@m.c>
  Proper Name 4 <proper@m.c>
  Testuser <newmmentry@m.c>

A commit with improperly formatted user field should not break the filter
  $ echo "some more test content" > testfile1
  $ hg commit -m "Commit with improper user field" -u "Improper user"
  $ hg log -T "{mailmap(author)}\n" -r "all()"
  Proper <proper@m.c>
  Proper Name 2 <commit2@m.c>
  Proper Name 3 <proper@m.c>
  Proper Name 4 <proper@m.c>
  Testuser <newmmentry@m.c>
  Improper user

No TypeError beacause of invalid input

  $ hg log -T '{mailmap(termwidth)}\n' -r0
