remotenames: introduce new template keywords for remotenames

This patch introduces three new template keywords 'remotenames',
'remotebookmarks', 'remotebranches' to show remotenames, remotebookmarks and
remotebranches associated to a changeset.

This is a part of moving hgremotenames extension to core. The remotenames
template keyword was present in the extension and the rest of the two are not
present in the hgremotenames extension and are introduced in this patch.

Source bundle was generated with the following script:

# hg init

# ln -s a l
# hg ci -Ama -d'0 0'
# mkdir b
# echo a > b/a
# chmod +x b/a
# hg ci -Amb -d'1 0'

  $ hg init
  $ hg -q pull "$TESTDIR/bundles/test-manifest.hg"

The next call is expected to return nothing:

  $ hg manifest

  $ hg co

  $ hg manifest

  $ hg files -vr .

           1 l l
  $ hg files -r . -X b

  $ hg manifest tip

  $ hg manifest --all

The next two calls are expected to abort:

  $ hg manifest -r 2
  abort: unknown revision '2'!
