This reworks/modernizes the tar/raw import logic and adds the following new features: - Adds the ability to control btrfs subvol and quota behaviour which was previously always on via an env var and cmdline arg - Adds control whether to sync() stuff after writing it, similar via env var + cmdline arg - Similar, the QCOW2 unpacking logic that was previously the implied default may now be controlled via env var + cmdline arg. - adds a "direct" mode. In this mode, the systemd-import tool can be used as a simple tool for decompressing/unpacking/installing arbitrary files, without all the additional meta data and auxiliary resources, i.e. outside of the immediate disk image context. Via the new --offset= and --size-max= switches the downloaded data can be written to specific locations of a file (which is particularly useful to use the tool to download fs images and write them to a partition location before actually creating the partition). We'll later use the latter feature for "sysupdate" concept, where images can be directly be written to partitions. That way the systemd-import binary will be used as backend for both "systemd-importd" and "systemd-sysupdate" and share most of the same code.
