doc: integrate graphviz graphs in tutorials

Use the mercurial-graphviz extension
(https://bitbucket.org/octobus/mercurial_graphviz) in tutorials in order to
have some dot graphs in the tutorials .t files.

In order to run the tests, export the GRAPHVIZ_EXTENSION variable which points
to your copy of the extension. Please be aware that pygraphviz should be
installed in your environment.

That should be sufficient for generating dot graphs in text format.

Then generate the doc as usual, the sphinx-graphviz extension (http://www
.sphinx-doc.org/en/stable/ext/graphviz.html) has been added and it should
handle the generation of the graphs. Please be aware that you need the dot
binary installed in your system. Please refer to the extension documentation
for more configuration.

Test NGTip feature
==================

Simple linear case

  $ echo babar >> jungle
  $ hg add jungle
  $ hg ci -t elephant -m babar

  $ hg log -G
  @  4 (elephant) babar
  |
  o  3 () c_delta
  |
  o  2 () c_gamma
  |
  o  1 () c_beta
  |
  o  0 () c_alpha
  
  $ hg log -r 'ngtip(.)'
  3 () c_delta
  $ hg log -r 'default'
  3 () c_delta


multiple heads with topic

  $ hg up "desc('c_beta')"
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ echo zephir >> jungle
  $ hg add jungle
  $ hg ci -t monkey -m zephir
  $ hg log -G
  @  5 (monkey) zephir
  |
  | o  4 (elephant) babar
  | |
  | o  3 () c_delta
  | |
  | o  2 () c_gamma
  |/
  o  1 () c_beta
  |
  o  0 () c_alpha
  
  $ hg log -r 'ngtip(.)'
  3 () c_delta
  $ hg log -r 'default'
  3 () c_delta

one of the head is a valid tip

  $ hg up "desc('c_delta')"
  2 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo epsilon >> epsilon
  $ hg add epsilon
  $ hg ci -m "c_epsilon"
  $ hg log -G
  @  6 () c_epsilon
  |
  | o  5 (monkey) zephir

  o  1 () c_beta

  o  0 () c_alpha
  
  $ hg log -r 'ngtip(.)'

  $ hg log -r 'default'
