diff-tree.c: load notes machinery when required
Since its introduction in 7249e91 (revision.c: support --notes
command-line option, 2011-03-29), combining '--notes' with any option
that causes us to format notes (e.g., '--pretty', '--format="%N"', etc)
results in a failed assertion at runtime.
$ git rev-list HEAD | git diff-tree --stdin --pretty=medium --notes
commit 8f3d9f354286745c751374f5f1fcafee6b3f3136
git: notes.c:1308: format_display_notes: Assertion `display_notes_trees' failed.
Aborted
This failure is due to diff-tree not calling 'load_display_notes' to
initialize the notes machinery.
Ordinarily, this failure isn't triggered, because it requires passing
both '--notes' and another of the above mentioned options. In the case
of '--pretty', for example, we set 'opt->verbose_header', causing
'show_log()' to eventually call 'format_display_notes()', which expects
a non-NULL 'display_note_trees'.
Without initializing the notes machinery, 'display_note_trees' remains
NULL, and thus triggers an assertion failure.
Fix this by initializing the notes machinery after parsing our options,
and harden this behavior against regression with a test in t4013. (Note
that the added ref in this test requires updating two unrelated tests
which use 'log --all', and thus need to learn about the new refs).
