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.

machined: add early checks for unrealistically large image/pool sizes

util-lib: split out allocation calls into alloc-util.[ch]

user-util: move UID/GID related macros from macro.h to user-util.h

bus-util: support details in CheckAuthorization calls Extra details for an action can be supplied when calling polkit's CheckAuthorization method. Details are a list of key/value string pairs. Custom policy can use these details when making authorization decisions.

sd-bus: drop bus parameter from message callback prototype This should simplify the prototype a bit. The bus parameter is redundant in most cases, and in the few where it matters it can be derived from the message via sd_bus_message_get_bus().

machined,machinectl: add calls for changing container/VM quotas

remove unused includes This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.

logind: open up most bus calls for unpriviliged processes, using PolicyKit Also, allow clients to alter their own objects without any further priviliges. i.e. this allows clients to kill and lock their own sessions without involving PK.

machined: open up most of machined's commands to unprivileged clients via PolicyKit

machined: refer to the disk space allocated for an image to "usage" rather than "size" After all, it's closer to the "du"-reported value than to the file sizes...

machined: Fix MarkReadOnly method's name on bus

machined: don't look for images on each property get, but cache the image object inbetween

machined: add support for reporting image size via btrfs quota

machinectl/machined: implement "rename", "clone", "read-only" verbs for machine images

machined: add "machinectl remove" for removing images

machined: Move image discovery logic into src/shared, so that we can make use of it from nspawn

machined: beef up machined image listing with creation/modification times of subvolumes We make use of the btrfs subvol crtime for this, and for gpt images of a manually managed xattr, if we can.

machined: add a full bus object for images
