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.

tree-wide: sort includes in *.h This is a continuation of the previous include sort patch, which only sorted for .c files.

importd: add new bus calls for importing local tar and raw images This also adds "machinectl import-raw" and "machinectl import-tar" to wrap these new bus calls. THe commands basically do for local files that "machinectl pull-raw" and friends do for remote files.

import: make image verification optional

import: port pull-raw to helper tools implemented for pull-tar This allows us to reuse a lot more code, and simplify pull-raw drastically.

util: make http url validity checks more generic, and move them to util.c

Move DEFINE_TRIVIAL_CLEANUP_FUNC to macro.h This remove the need for various header files to include the (relatively heavyweight) util.h.

import: rename "gpt" disk image type to "raw" After all, nspawn can now dissect MBR partition levels, too, hence ".gpt" appears a misnomer. Moreover, the the .raw suffix for these files is already pretty popular (the Fedora disk images use it for example), hence sounds like an OK scheme to adopt.
