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.

Multiple security issues including data race, buffer overflow, and uninitialized memory drop

arr crate contains multiple security issues. Specifically,

  1. It incorrectly implements Sync/Send bounds, which allows to smuggle non-Sync/Send types across the thread boundary.
  2. Index and IndexMut implementation does not check the array bound.
  3. Array::new_from_template() drops uninitialized memory.
