0923b4253c tree-wide: replace "plural(s)" by "plurals"
(s) is just ugly with a vibe of DOS. In most cases just using the normal plural
form is more natural and gramatically correct.

There are some log_debug() statements left, and texts in foreign licenses or
headers. Those are not touched on purpose.

047273e6e8 pcrphase: add two additional phases
This adds two more phases to the PCR boot phase logic: "sysinit" +
"final".

The "sysinit" one is placed between sysinit.target and basic.target.
It's good to have a milestone in this place, since this is after all
file systems/LUKS volumes are in place (which sooner or later should
result in measurements of their own) and before services are started
(where we should be able to rely on them to be complete).

This is particularly useful to make certain secrets available for
mounting secondary file systems, but making them unavailable later.

This breaks API in a way (as measurements during runtime will change),
but given that the pcrphase stuff wasn't realeased yet should be OK.

55c041b4e4 tree-wide: also settle on "initrd" instead of "initial RAM disk"
With this the concept is now called the same way everywhere except where
historical info is relevant or where the other names are API.

a434e25f52 measure: make --public-key= optional if "sign" is called
We can derive the public key from the private key, so let's do that, to
make things a bit easier.

127b72da2b measure: add --current switch for "systemd-measure calculate"
This allows allows shortcutting measurements of the specified files and
use the information from /sys/ instead.

This is not too useful on its own given that "systemd-measure status"
already exists which displays the current, relevant PCR values. The main
difference is how "complete" the information is. "status" will detect if
the measurements make any sense, and show more than PCR 11. "calculate
--current" otoh only reads PCR 11 and uses that, and that's really it.

This is mainly preparation for later work to add PCR signing to the
tool, where usually it makes most sense to sign prepared kernel images,
but for testing it's really useful to shortcut signing to the current
PCR values instead

ca1092dc15 measure: add new tool to precalculate PCR values for a kernel image
For now, this simply outputs the PCR hash values expected for a kernel
image, if it's measured like sd-stub would do it.

(Later on, we can extend the tool, to optionally sign these
pre-calculated measurements, in order to implement signed PCR policies
for disk encryption.)
