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.

# Misbehaving `HandleLike` implementation can lead to memory safety violation
Unsafe code in `ObjectPool` has time-of-check to time-of-use (TOCTOU) bug that
can eventually lead to a memory safety violation. `ObjectPool` and `HandlePool`
implicitly assumes that `HandleLike` trait methods are pure, i.e., they always
return the same value. However, this assumption is unsound since `HandleLike`
is a safe, public trait that allows a custom implementation.
