Lennart Poettering 897448bd37 sd-event: if signal nr has high bit set sd_event_add_signal() auto-block it via sigprocmask() 
So far we expected callers to block the signals manually. Which is
usually a good idea, since they should do that before forking off
threads and similar. But let's add a mode where we automatically block
it for the caller, to simplify things.

Yu Watanabe 778e3da95e sd-network: drop fallback values 
This drops spurious lines in `networkctl status` for unmanaged interfaces.
Before:
```
$ networkctl status --lines 0 lo
● 1: lo
                     Link File: n/a
                  Network File: n/a
                          Type: loopback
                         State: carrier (unmanaged)
                  Online state: unknown
                    HW Address: 00:00:00:00:00:00
                           MTU: 65536
                         QDisc: noqueue
  IPv6 Address Generation Mode: eui64
          Queue Length (Tx/Rx): 1/1
                       Address: 127.0.0.1
                                ::1
             Activation Policy: up
           Required For Online: yes
```
After:
```
$ networkctl status --lines 0 lo
● 1: lo
                     Link File: n/a
                  Network File: n/a
                         State: carrier (unmanaged)
                  Online state: unknown
                          Type: loopback
              Hardware Address: 00:00:00:00:00:00
                           MTU: 65536
                         QDisc: noqueue
  IPv6 Address Generation Mode: eui64
      Number of Queues (Tx/Rx): 1/1

                                ::1
```

That is, the lines for Activation Policy and Required For Online are
dropped.

Lennart Poettering 32e2767080 tree-wide: use the term "initrd" at most places we so far used "initramfs" 
In most cases we refernced the concept as "initrd". Let's convert most
remaining uses of "initramfs" to "initrd" too, to stay internally
consistent.

This leaves "initramfs" only where it's relevant to explain historical
concepts or where "initramfs" is part of the API (i.e. in
/run/initramfs).

This also drops unnecessary duplication of path.

Previously, even if sd_device_get_subsystem() returns -ENOENT for block

without solving them. See issues #24258 and #24124.

Yu Watanabe 4fe46c349d sd-device: rename devpath_from_devnum() -> devname_from_devnum() 
In sd-device, `devpath` is a kind of syspath without '/sys' prefix, e.g.
/devices/pci0000:00/0000:00:1c.4/0000:3c:00.0/nvme/nvme0/nvme0n1,
and `devname` is a path to the device node, e.g. /dev/nvme0n1.

Let's use the consistent name for the helper function.
