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.

traitobject assumes assumes the layout of fat pointers

This crate gets the data pointer from fat pointers assuming that the first element in a fat pointer is the data pointer. This is currently true, but it may change in a future Rust version, leading to memory corruption.

This has been fixed in the master branch of the crate, but is has not been released into crates.io.
