[dm-crypt] FAQ rework for LUKS2: First pass done

[Arno Wagner <arno@wagner.name>]

Hi all,

I just finished the firsy pass through the FAQ to adapt it for LUKS2.
In particular I did the following:

- Clearly state LUKS1 or LUKS2 for things that do not apply to both
- Still uses "LUKS" when both LUKS1 or LUKS2 are affected
- Added references for LUKS2 header spec
- Added specific instructions for LUKS2 where needed
- Added a (currently pretty short) LUKS2 section

If some of you find the time to read through it and let me know
about any errors or omissions, I would apprecitate it.

Also, if you have any suggestions for Section 10 (LUKS2 Questions),
or mabybe even a small item to add, I would appreciate that as
well. In particular, the LUKS2 section would benefit from some
mini-HOWTOs, I think.

As usual, the FAQ is found at 
   https://gitlab.com/cryptsetup/cryptsetup/-/wikis/FrequentlyAskedQuestions

I did update the version in the sources as well, but that may take a while
to propagate.

Regards,
Arno
