[PATCH v2 0/1] plainmount: Support plain encryption mode.

[Maxim Fomin]

This patch adds support for plain encryption mode (plain dm-crypt) via
new module/command named 'plainmount'. This is the second version of the
patch send at 
https://lists.gnu.org/archive/html/grub-devel/2022-01/msg00179.html.

The patch was significantly rewritten. Notable changes are:
1. removing UUID code - UUID path can be supported by other grub tools
(grub probe and search), thus avoiding code duplication.

2. option -p (specify password, usefull for testing) was added as an
alternative for console interactive password prompt.

3. K/M/G offset suffix support was added - previously offsets were
specified as 512 byte blocks.

4. removed grub_print_error() inside plainmount internal functions -
all errors are reported when grub command exits.

5. other minor coding changes. Error handling in cryptodisk_setkey() was
refactored in dedicated function in order to handle GPG errors uniformly.
However, the way GPG errors are handled was not changed due to reasons
mentioned in previous discussion. Option -Z (sector size) was renamed to
-S. Also, unique cryptodisk UUIDs were added.
