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.

shared: include what we use The next step of a general cleanup of our includes. This one mostly adds missing includes but there are a few removals as well.

selinux: split up mac_selinux_have() from mac_selinux_use() Let's distuingish the cases where our code takes an active role in selinux management, or just passively reports whatever selinux properties are set. mac_selinux_have() now checks whether selinux is around for the passive stuff, and mac_selinux_use() for the active stuff. The latter checks the former, plus also checks UID == 0, under the assumption that only when we run priviliged selinux management really makes sense. Fixes: #1941

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

util-lib: split out globbing related calls into glob-util.[ch]

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

src/basic: rename audit.[ch] → audit-util.[ch] and capability.[ch] → capability-util.[ch] The files are named too generically, so that they might conflict with the upstream project headers. Hence, let's add a "-util" suffix, to clarify that this are just our utility headers and not any official upstream headers.

util-lib: move string table stuff into its own string-table.[ch]

util-lib: split stat()/statfs()/stavfs() related calls into stat-util.[ch]

util-lib: move mount related utility calls to mount-util.[ch]

util-lib: split string parsing related calls from util.[ch] into parse-util.[ch]

util-lib: split out fd-related operations into fd-util.[ch] There are more than enough to deserve their own .c file, hence move them over.

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.

util: split out extract_first_word() and related calls into extract-word.[ch] This is quite a lot of code these days, hence move it to its own source file.

basic: rework virtualization detection API Introduce a proper enum, and don't pass around string ids anymore. This simplifies things quite a bit, and makes virtualization detection more similar to architecture detection.

util: Don't interpret quotes by default in extract_first_word This adds an EXTRACT_QUOTES option to allow the previous behaviour, of not interpreting any character inside ' or " quotes as separators.

util: change unquote_*_word to extract_*_word It now takes a separators argument, which defaults to WHITESPACE if NULL is passed.

path-util: Change path_is_mount_point() symlink arg from bool to flags This makes path_is_mount_point() consistent with fd_is_mount_point() wrt. flags.

util: split all hostname related calls into hostname-util.c

util: rework word parsing and c unescaping code When parsing words from input files, optionally automatically unescape the passed strings, controllable via a new flags parameter. Make use of this in tmpfiles, and port everything else over, too. This improves parsing quite a bit, since we no longer have to process the same string multiple times with different calls, where an earlier call might corrupt the input for a later call.

shared/condition: fix gcc5 warning Fixes the warning below. src/shared/condition.c: In function ‘condition_new’: src/shared/condition.c:47:27: warning: logical not is only applied to the left hand side of comparison [-Wlogical-not-parentheses] assert(!parameter == (type == CONDITION_NULL)); ^ src/shared/macro.h:42:44: note: in definition of macro ‘_unlikely_’ #define _unlikely_(x) (__builtin_expect(!!(x),0)) ^ src/shared/macro.h:226:22: note: in expansion of macro ‘assert_se’ #define assert(expr) assert_se(expr) ^ src/shared/condition.c:47:9: note: in expansion of macro ‘assert’ assert(!parameter == (type == CONDITION_NULL)); ^

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.

util: rework strappenda(), and rename it strjoina() After all it is now much more like strjoin() than strappend(). At the same time, add support for NULL sentinels, even if they are normally not necessary.

condition: don't include files from src/core

tree-wide: make condition_free_list return NULL

util: introduce our own gperf based capability list This way, we can ensure we have a more complete, up-to-date list of capabilities around, always.

remove duplicated includes

util: rework /proc/cmdline parser to use unquote_first_word()

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

shared: rename condition-util.[ch] to condition.[ch] Now that we only have one file with condition implementations around, we can drop the -util suffix and simplify things a bit.
