Rename interfaces to bring consistency with previous pid->runtime type
renaming. See PR #106 or 69a403cd original type renaming.
Interfaces that are still in use were renamed with a compatibility
interface. Unused interfaces were fully deprecated for removal.

When SECMARK or Netlabel packet labeling is used, it's useful to
forbid receiving and sending unlabeled packets. If packet labeling is
not active, there's no effect.

Add EFI bootloaders rEFInd and systemd-boot. Boot tools which manage
bootloader files in UEFI (DOS) partition need also to manage UEFI boot
variables in efivarfs. Bootctl (systemd-boot tool) verifies the type
of EFI file system and needs to mmap() the files.

In many cases, this won't result in a change in the actual policy generated, but if the definitions of macros are changed going forward, the mismatches could cause issues.

Usbguard enforces the USB device authorization policy for all USB
devices. Users can be authorized to manage rules and make device
authorization decisions using a command line tool.
Add rules for usbguard. Optionally, allow authorized users to control
the daemon, which requires usbguard-daemon to be able modify its rules
in /etc/usbguard.

Modern systems shouldn't need direct access to raw memory
devices (/dev/mem, /dev/kmem, /dev/mergemem, dev/oldmem, /dev/port)
anymore, so let's remove the access in most cases and make it tunable
in the rest.
Add dev_read_raw_memory_cond(), dev_write_raw_memory_cond() and
dev_wx_raw_memory_cond(), which are conditional to new boolean
allow_raw_memory_access.
Remove raw memory access for a few domains that should never have
needed it (colord_t, iscsid_t, mdamd_t, txtstat_t), should not need it
anymore (dmidecode_t, Debian devicekit_diskt_t, hald_t, hald_mac_t,
xserver_t) or the domains that should transition to different domain
for this (rpm_t, kudzu_t, dpkg_t).

On a Debian 10 test virtual machine, when installing packages adds a
group, the following AVC occurs:
type=USER_AVC msg=audit(1578863991.588:575): pid=381 uid=104
auid=4294967295 ses=4294967295 subj=system_u:system_r:system_dbusd_t

Allow groupadd to use nss-systemd, which calls DBUS method
LookupDynamicUserByName().
