Draw the diffstat bars as SVG

The bars were cells spanning up to 1000 columns of a nested table, which
kept them free of inline styles under a strict CSP but broke the HTML
table model, 18 errors on a commit page, and left Firefox's longest bar
short of the full width. An SVG canvas sized by its attributes is just
as safe under a CSP, validates, and draws every bar exactly to scale.
