Among other things this changes tracking of the location of resources
during GC from using the BootEntrySource enum rather than a path, since
we have that and it is more efficient and easier to grok.
The reworks the ESP/XBOOTLDR logic to pin the ESP/XBOOTLDR via an fd,
and return that as optional return parameter.
So far we only pinned the parent dir of the ESP/XBOOTLDR, which was
useful when verifying that ESP/XBOOTLDR is actually a mount point by
comparing mount ids. This however became obsolete with
a98a6eb95c. Hence, let's clean this up,
and pin the inode we really care about and return it.
Let's not leak details from src/shared and src/libsystemd into
src/basic, even though you can't actually do anything useful with
just forward declarations from src/shared.
The sd-forward.h header is put in src/libsystemd/sd-common as we
don't have a directory for shared internal headers for libsystemd
yet.
Let's also rename forward.h to basic-forward.h to keep things
self-explanatory.
I think the current behaviour of not doing EFI variables when we are run
in a container makes a ton of sense, but in some cases it's useful to
do EFI var setup even when a set of namespaces is set up for us, for
example to recover a hosed installation from a rescue disk.
While we are at it, let's remove some duplicate checks, and
systematically output information why we skip various operations.
Fixes: #36174#35005
This allows loading the X.509 certificate from an OpenSSL provider
instead of a file system path. This allows loading certficates directly
from hardware tokens instead of having to export them to a file on
disk first.
