2016-07-21bootctl: move toupper() implementation to string-util.hLennart Poettering
We already have tolower() calls there, hence let's unify this at one place. Also, update the code to only use ASCII operations, so that we don't end up being locale dependant.
2016-05-30util-lib: make localed's nonempty() generic, rename it to empty_to_null() ↵Lennart Poettering
and make use of it everywhere
2016-05-17basic: define HEXDIGITSDaniel Kahn Gillmor
define HEXDIGITS alongside DIGITS, and use it where it's already useful. We'll use it again shortly when parsing MAC addresses.
2016-02-10tree-wide: remove Emacs lines from all filesDaniel Mack
This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.
2016-01-13basic: add ascii_strcasecmp_nn() callLennart Poettering
In contrast to ascii_strcasecmp_nn() it takes two character buffers with their individual length. It will then compare the buffers up the smaller size of the two buffers, and finally the length themselves.

2015-11-30basic: include only what we useThomas Hindoe Paaboel Andersen
This is a cleaned up result of running iwyu but without forward declarations on src/basic.

2015-11-02string-util: rework memory_erase() so that it cannot be optimized awayLennart Poettering
memory_erase() so far just called memset(), which the compiler might optimize away under certain conditions if it feels there's benefit in it. C11 knows a new memset_s() call that is like memset(), but may not be optimized away. Ideally, we'd just use that call, but glibc currently does not support it. Hence, implement our own simplistic version of it. We use a GCC pragma to turn off optimization for this call, and also use the "volatile" keyword on the pointers to ensure that gcc will use the pointers as-is. According to a variety of internet sources, either one does the trick. However, there are also reports that at least the volatile thing isn't fully correct, hence let's add some snake oil and employ both techniques. https://news.ycombinator.com/item?id=4711346
2015-10-27util: move string_is_safe() to string-util.[ch]Lennart Poettering
2015-10-24util-lib: split our string related calls from util.[ch] into its own file ↵Lennart Poettering
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.
