[PATCH v2 0/7] common: Introduce crypt-style password support

[Steffen Jaeckel]

This patchset introduces support for crypt-style passwords to unlock
the console in autoboot mode.

The implementation of crypt-sha256 and crypt-sha512 originate from
libxcrypt at https://github.com/besser82/libxcrypt.git
Version v4.4.17
Git commit hash 6b110bc

I didn't re-format those two files to make diffing to the original
versions from libxcrypt easier, which leads to a huge load of
checkpatch.pl warnings&errors. Please advise on whether they should be
re-formatted or can be kept as is.

The remaining warnings from checkpatch.pl are intentional resp. open for
discussion.

A sandbox defconfig with password entry has been added. I'm not sure
whether this should be kept or not, it's just there as an example.

Cheers,
Steffen
