0e15c14f63 tpm2: add bind key
Currently, the tpm2 support will use encrypted sessions by creating a
primary key that is used to encrypt traffic. This creates a problem as
the key created for encrypting the traffic could be faked by an active
interposer on the bus. In cases when a pin is used, we can introduce the
bind key. The pin is used as the auth value for the seal key, aka the
disk encryption key, and that auth value can be used in the session
establishment. An attacker would need the pin value to create the secure
session and thus an active interposer without the pin could not
interpose on TPM traffic.

b5b7879a5d repart: Add support for formatting verity partitions
This commit adds a new Verity= setting to repart definition files
with two possible values: "data" and "hash".

If Verity= is set to "data", repart works as before, and populates
the partition with the content from CopyBlocks= or CopyFiles=.

If Verity= is set to "hash", repart will try to find a matching
data partition with Verity=data and equal values for CopyBlocks=
or CopyFiles=, Format= and MakeDirectories=. If a matching data
partition is found, repart will generate verity hashes for that
data partition in the verity partition. The UUID of the data
partition is set to the first 128 bits of the verity root hash. The
UUID of the hashes partition is set to the final 128 bits of the
verity root hash.

Fixes #24559

Hence, this should not change the current behavios.

f2f7785d7a busctl: Add introspect support for methods with same name but different signature
D-Bus interfaces can have multiple methods with the same name, as long
as they have different arguments (signature). Currently busctl can call
those methods but when introspecting the interface it just displays
"Duplicate method"

This PR fixes the behavior, by also adding the signature to the hash for
the members set.

Before this patch:

$ busctl introspect org.asamk.Signal /org/asamk/Signal
Invalid introspection data: duplicate method 'sendMessage' on interface 'org.asamk.Signal'.

After this patch:

$ busctl introspect org.asamk.Signal /org/asamk/Signal
NAME                                TYPE      SIGNATURE RESULT/VALUE FLAGS
org.asamk.Signal                    interface -         -            -
.sendMessage                        method    as        x            -
.sendMessage                        method    s         x            -

Calling the methods already works as expected, as the user must specify
the signature explicitely:
busctl --user call org.asamk.Signal /org/asamk/Signal org.asamk.Signal sendMessage "as" 2 foo bar
busctl --user call org.asamk.Signal /org/asamk/Signal org.asamk.Signal sendMessage "s" foo

$ busctl --xml introspect org.asamk.Signal /org/asamk/Signal

90782fde46 test: don't fail if we don't need any external nss libs
On certain systems the `install_libnss()` function might end up with an
empty list of libraries to install, which triggers an assertion in
`image_install()`:

```
I: Install libnss
..//test-functions: line 2721: 1: parameter null or not set
make: *** [Makefile:4: setup] Error 1
```

E.g.:
```
# LD_DEBUG=files getent passwd 2>&1 >/dev/null | sed -n '/calling init: .*libnss_/ {s!^.* /!/!; p}'
/lib64/libnss_sss.so.2
/lib64/libnss_systemd.so.2
# dnf -y remove sssd-client systemd-libs
# LD_DEBUG=files getent passwd 2>&1 >/dev/null | sed -n '/calling init: .*libnss_/ {s!^.* /!/!; p}'
<no output>
```

Let's handle this case gracefully.
