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 Sort the includes accoding to the new coding style.

util-lib: move /proc/cmdline parsing code to proc-cmdline.[ch]

util-lib: split our string related calls from util.[ch] into its own file string-util.[ch] There are more than enough calls doing string manipulations to deserve its own files, hence do something about it. This patch also sorts the #include blocks of all files that needed to be updated, according to the sorting suggestions from CODING_STYLE. Since pretty much every file needs our string manipulation functions this effectively means that most files have sorted #include blocks now. Also touches a few unrelated include files.

tree-wide: whenever we fork off a foreign child process reset signal mask/handlers Also, when the child is potentially long-running make sure to set a death signal. Also, ignore the result of the reset operations explicitly by casting them to (void).

shared: add process-util.[ch]

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.

delta: diff returns 1 when files differ, ignore this https://bugs.debian/org/771397

treewide: use log_*_errno whenever %m is in the format string If the format string contains %m, clearly errno must have a meaningful value, so we might as well use log_*_errno to have ERRNO= logged. Using: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/' Plus some whitespace, linewrap, and indent adjustments.

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().

util: simplify proc_cmdline() to reuse get_process_cmdline() Also, make all parsing of the kernel cmdline non-fatal.

stop complaining about unknown kernel cmdline options Also stop warning about unknown kernel cmdline options in the various tools, not just in PID 1

util: move more intellegince into parse_proc_cmdline() Already split variable assignments before invoking the callback. And drop "rd." settings if we are not in an initrd.

Extract looping over /proc/cmdline into a shared function In cryptsetup-generator automatic cleanup had to be replaced with manual cleanup, and the code gets a bit longer. But existing code had the issue that it returned negative values from main(), which was wrong, so should be reworked anyway.

util: unify reading of /proc/cmdline Instead of individually checking for containers in each user do this once in a new call proc_cmdline() that read the file only if we are not in a container.

quota: use QUOTACHECK path correctly as tested in configure.ac https://bugs.freedesktop.org/show_bug.cgi?id=63555

honor SELinux labels, when creating and writing config files Also split out some fileio functions to fileio.c and provide a SELinux aware pendant in fileio-label.c see https://bugzilla.redhat.com/show_bug.cgi?id=881577

fsck: remove distro specific hacks from fsck/quotacheck Move forcefsck file checks under a HAVE_SYSV_COMPAT #ifdef, and warn if this is used.

cryptsetup: allow configuration of LUKS disks via the kernel cmdline This generalizes a bit of the functionality already available in dracut.

move all tools to subdirs
