'systemd-analyze security' (available since systemd v240) makes a nice
overall evaluation of hardening levels of services in a system. More
details can be found with 'systemd-analyze security SERVICE' for each
service.

Detect tools for dm-integrity and dm-verity, check if some devices
in /dev/mapper/* use them and especially the system root device.

Manual page crypt(5) gives recommendations for choosing password
hashing methods, so let's check if there are weakly encrypted
passwords in the system.

There are several challenges with the existing method of using
/etc/crypttab:
1)encrypted rootfs partitions are not typically listed in this
file (users are prompted for password in early boot instead)
2)the 'luks' option is the default option so it is possible for
/etc/crypttab entries to never have this set explicitly and any
block device configured as such will be missed currently
3)any device mounted manually, or using any other mechanism aside
from /etc/crypttab will be missed
This commit executes 'cryptsetup isLuks' on every block device in
the system to determine whether it is a LUKS device. This handles
all 3 cases mentioned above.
Test case wording was also updated to reflect the fact that it
only checks for LUKS entrypted block devices. So, plain dm-crypt
and TrueCrypt/VeraCrypt block device encryption is not detected.
Nor is any file system level encryption such as eCryptfs, EncFs,
gocryptfs.
Adds a test to detect systemd-boot. The 'bootctl' binary is also
added as this is the utility used to inspect the systemd-boot
configuration.
This test is only executed if systemd is installed, the bootctl
utility exists and the system is booted in UEFI mode.
* Added kernel.dmesg_restrict to sysctl checks.
* Initial addition of tests_usb_devices
* More updates for tests_usb_devices
* More updates
* Updated logging and other output.
