graphmod: allow for different styles for different edge types

Rather than draw all edges as solid lines, allow for using different styles for
different edge types. For example you could use dotted lines for edges that
do not connect to a parent, and dashed lines when connecting to a grandparent
(implying missing nodes in between).

For example, setting the following configuration:

    [ui]
    graphstyle.grandparent = :
    graphstyle.missing = .

would result in a graph like this:

  o    changeset:   32:d06dffa21a31

Edge styles can be altered by setting the following one-character config options::

    [ui]
    graphstyle.parent = |
    graphstyle.grandparent = :
    graphstyle.missing = .

The default configuration leaves all 3 types set to |, leaving graph styles
unaffected.

This is part of the work towards moving smartlog upstream; currently smartlog
injects extra nodes into the graph to indicate grandparent relationships (nodes
elided).
