Send a response to cryptprompt

Pass encrypted device to cryptprompt

Add cryptprompt kernel param to run a custom prompt

Store passphrase in linux keyring

Caveats:
- The linux keyring is hardcoded and created in initramfs-init instead
  of by another binary
- The permission set for the keyring are not secure
- The keyring & key are chown'd to a hardcoded uid
- The changes always occur instead of being behind a flag

Prevent overriding mkinitfs while developing

support specifying root device by partuuid

mkinitfs: allow specifying compression level

(and perhaps injecting more options)

the defaults are taken from before:

gzip: -9 -> -9
xz: unspecified (-1)! -> -9
zstd: -19 -> -19
lz4: --best(-12) -> -12
