YubiKey 4 series GPG and SSH setup guide

Written for fairly adept technical users, preferably of Debian GNU/Linux, not for absolute beginners.

You'll probably be working with a single smartcard, so you'll want only one primary key (1. Sign & Certify) and two associated subkeys (2. Encrypt, 3. Authenticate). I've published a Bash function which automates this slightly special key generation process.

Every atomic object has a timeline (TL) of writes:
- A write is either a store or a read-modify-write (RMW): it read latest write & pushed new one.
- A write is either tagged Relaxed, Release, or SeqCst.
- A read observes some write on the timeline:
  - On the same thread, future reads can't go backwards on the timeline.
  - A read is either tagged Relaxed, Acquire, or SeqCst.
  - RMWs can also be tagged Acquire (or AcqRel). If so, the Acquire refers to the "read" portion of "RMW".
Each thread has its own view of the world:

Shared write timelines but each thread could be reading at different points.
