ui-log: Change display of full commit messages (and notes)

When showmsg is enabled, ui-log (in addition to the table row containing
the details of the current commit) adds a second table row containing the
remainder of the commit message, and yet another table row containing the
commit notes (if any). The vertical margins between commit subject, commit
message and commit notes are controlled by CSS.

In preparation for the commit graph (which will be printed to the left of
the commit message/notes) we need to eliminate these vertical margins (as
they would produce ugly gaps in the commit graph) and instead achieve them
by adding newlines to the commit message/notes. Furthermore, we can no
longer print the "Notes:" header in the "Age" column, since the graph will
be drawn between the "Age" column and the "Commit message" column.

This patch therefore prepares the commit message and commit notes in a
single buffer (properly formatting the notes using the NOTES_SHOW_HEADER
and NOTES_INDENT flags to format_note()), and then prints the entire
buffer into a single table row.
