track-tags: write all tag changes to a file

The tag changes information we compute is now written to disk. This gives
hooks full access to that data.

The format picked for that file uses a 2 characters prefix for the action:

    -R: tag removed
    +A: tag added
    -M: tag moved (old value)
    +M: tag moved (new value)

This format allows hooks to easily select the line that matters to them without
having to post process the file too much. Here is a couple of examples:

 * to select all newly tagged changeset, match "^+",
 * to detect tag move, match "^.M",
 * to detect tag deletion, match "-R".

Once again we rely on the fact the tag tests run through all possible
situations to test this change.

Testing tagging with the EOL extension

  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > eol =
  > 
  > [eol]
  > native = CRLF
  > EOF

setup repository

  $ hg init repo
  $ cd repo
  $ cat > .hgeol <<EOF
  > [patterns]
  > ** = native
  > EOF
  $ printf "first\r\nsecond\r\nthird\r\n" > a.txt
  $ hg commit --addremove -m 'checkin'
  adding .hgeol
  adding a.txt

Tag:

  $ hg tag 1.0

Rewrite .hgtags file as it would look on a new checkout:

  $ hg update -q null
  $ hg update -q

Touch .hgtags file again:

  $ hg tag 2.0

  $ cd ..
