[PROCFS 0/5] Add and improve (proc) entries

[Glenn Washburn <development@efficientek.com>]

This patch series adds proc entries to show the user some of GRUB's internal
state on devices, loopback devices, and luks devices. This can be valuable
when debugging grub, either as a developer, or as a user trying to determine
why their config is not working as expected. Some of the same info can be
gotten from the "ls" command with no arguments, however the proc entry is a
lot less verbose, which is helpful when output is more than one screen's
worth of data.

Patch #1: Add (proc)/loopbacks which shows all configured loopback devices
Patch #2-4: Improve the existing luks proc entry by adding LUKS2 support,
  add field names for the cryptodisk names and source device names, and
  adding a header to make the file more easily comprehensible
Patch #5: Add (proc)/devices to show all devices grub knows about.
