tree-wide: remove Emacs lines from all files This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.

generators: rename add_{root,usr}_mount to add_{sysroot,sysroot_usr}_mount This makes it obvious that those functions are only usable in the initramfs. Also, add a warning when noauto, nofail, or automount is used for the root fs, instead of silently ignoring. Using those options would be a sign of significant misconfiguration, and if we bother to check for them, than let's go all the way and complain. Other various small cleanups and reformattings elsewhere.

Move x-systemd-device.timeout handling from core to fstab-generator Instead of adjusting job timeouts in the core, let fstab-generator write out a dropin snippet with the appropriate JobTimeout. x-systemd-device.timeout option is removed from Options= line in the generated unit. The functions to write dropins are moved from core/unit.c to shared/dropin.c, to make them available outside of core. generator.c is moved to libsystemd-label, because it now uses functions defined in dropin.c, which are in libsystemd-label.

generators: rework mount generators - Add support for finding and mounting /srv based on GPT data, similar to how we already handly /home. - Share the fsck logic between GPT, EFI and fstab generators - Make sure we never run the EFI generator inside containers - Drop DefaultDependencies=no from EFI mount units - Other fixes
