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.

HeaderMap::Drain API is unsound

Affected versions of this crate incorrectly used raw pointer, which introduced unsoundness in its public safe API.

Failing to drop the Drain struct causes double-free, and it is possible to violate Rust's alias rule and cause data race with Drain's Iterator implementation.

The flaw was corrected in 0.1.20 release of http crate.
