Tony Arcieri ac125ee29a Translate database into V3 advisory format (#420) 
As proposed in #240 and tracked in #414, this PR translates all
advisories into the new "V3" advisory format, which is based on Markdown
with leading TOML front matter.

This format makes it easier to see rendered Markdown syntax
descriptions, whether rendered by an IDE or GitHub. This should help
with both crafting advisories initially as well as review, and ideally
encourages more lengthy descriptions.

Support for this format shipped in `cargo-audit` v0.12.0 on
May 6th, 2020.

Uncontrolled recursion leads to abort in HTML serialization

Affected versions of this crate did use recursion for serialization of HTML DOM trees.

This allows an attacker to cause abort due to stack overflow by providing a pathologically nested input.

The flaw was corrected by serializing the DOM tree iteratively instead.
