If there is no free loop device, the call of loopsetup -f will create one and return it. For this it needs privilege escalation.
It doesn't need those, if there is already an used device, but that cannot be guaranteed.
Closes#436
* KDF support for argon2 memory intensive algorithm
following many requests, here is support for argon2 KDF to be switched
on using --kdftype argon2 (--kdf iterations --kdfmem memory)
effective memory required is 2^memory KiB, defaults to 18 (262 MiB)
number of iterations are still specified as --kdf argument
requires the argon2 reference C implementation from P-H-C
also requires tomb-kdb-pbkdf2-gensalt in extras/kdf-keys
example usage:
tomb forge -k argon.key --kdf 10 --kdftype argon2
* manual updates for argon2
* small improvements to loopback setup and --sudo
* support reading hostname from file
also tolerate not finding the hostname (fill localhost)
address #428
* cleanup and support sup,sud,pkexec

now supporting also pkexec (polkit daemon), suckless' sup and
sud.dyne.org
pkexec is autodetected when polkit is running
manpage documents the --sudo flag which overrides any autodetection
Depending script invokation, behavior is not exactly similar.
Assuming that if SUDO_USER is set, the _sudo invokation can be dropped (EUID=0).
In the other case, user has created file, owner is already good, don't call chown.
Preparation:
$ tomb dig foo.tomb -s 10
Method 1:
$ sudo tomb forge foo.tomb.key -v
Method 2:
$ tomb forge foo.tomb.key -v
... ask user password to gain superuser privileges
...
Sorry, user <username> is not allowed to execute '/bin/chown <uid>:<gid> foo.tomb.key' as root on <hostname>.

check works both for empty ("") and non-existing vars and is a fix
for regression #398 to work on older Zsh versions. It is normalized
through all tomb's code.
