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.

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

udevadm,..: make --help output of udev tools more like the output of the various other tools

udev: net_setup - fix warning

treewide: no need to negate errno for log_*_errno() It corrrectly handles both positive and negative errno values.

treewide: auto-convert the simple cases to log_*_errno() As a followup to 086891e5c1 "log: add an "error" parameter to all low-level logging calls and intrdouce log_error_errno() as log calls that take error numbers", use sed to convert the simple cases to use the new macros: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/' Multi-line log_*() invocations are not covered. And we also should add log_unit_*_errno().

udev: net_setup_link - export the .link filename applied to the link

udev: net_setup_link builtin should print the reason why something fails Let's tell users what is going wrong.

udev - link-setup - expose ID_NET_DRIVER This is the same as shown by 'ethtool -i <ifname>', and is sometimes set even though DRIVER is not.

Remove dead code and unexport some calls "make check-api-unused" informs us about code that is not used anymore or that is exported but only used internally. Fix these all over the place.

udev: link-config - let udevd set the ifname

udev: link-config - reset ctx on exit

udev: builtin - rename net_link to net_setup_link Also add shell completions.
