Recognise NBDs (Network Block Devices) (#247)
Network Block Devices are not displayed in GParted as partitionable
devices. They do appear in /proc/partitions, are reported by
fdisk -l [1] and by ped_device_probe_all() from libparted. Therefore
include them.
Create NBD device for testing:
# truncate -s 1G /tmp/disk-1G.img
# nbd-server -C /dev/null 9000 /tmp/disk-1G.img
# nbd-client localhost 9000 /dev/nbd0
After creating a couple of partitions for testing, the contents of
/proc/partitions looks like this:
# egrep 'name|nbd' /proc/partitions
major minor #blocks name
43 0 1048576 nbd0
43 1 262144 nbd0p1
43 2 785408 nbd0p2
Listing all disks using fdisk:
# fdisk -l
...
Disk /dev/nbd0: 1 GiB, 1073741824 bytes, 2097152 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x081b1cd1
Device Boot Start End Sectors Size Id Type
/dev/nbd0p1 2048 526335 524288 256M 83 Linux
/dev/nbd0p2 526336 2097151 1570816 767M 83 Linux
Temporarily apply this patch to GParted so that it ignores the devices it
currently selects from /proc/partitions to use what get_device_probe_all()
reports. GParted shows NBDs.

Closes #247 - GParted does not list NBD (Network Block Device) devices
in the GUI
Document future Debian/Ubuntu build time dependency in README (!121)
When preparing the GParted Live 1.6.0 distribution, which is based on
Debian unstable ("sid"), compiling GParted failed like this:
$ make
...
/usr/bin/msgfmt --desktop --template gparted.desktop.in -d ./po -o gparted.desktop
chmod +x gparted
/usr/bin/msgfmt --xml --template org.gnome.gparted.policy.in -d ./po -o org.gnome.gparted.policy

This was also previously reported in the GParted Forum [1]. Future
Debian 13 ("trixie") and Ubuntu 24.04 LTS ("nobel") releases have moved
the needed gettext translation rules for .policy XML files:
/usr/share/gettext/its/policy.its
/usr/share/gettext/its/policy.loc
to new package libpolkit-gobject-1-dev not installed by default.
Document this new build time dependency.
Also see commits [2][3] where the equivalent change was needed in the
Alpine Linux and CentOS continuous integration images.
