2015-10-26process-util: move more process related calls to process-util.[ch]Lennart Poettering
2015-10-26util-lib: split out user/group/uid/gid calls into user-util.[ch]Lennart Poettering
2015-10-25util-lib: split out fd-related operations into fd-util.[ch]Lennart Poettering
There are more than enough to deserve their own .c file, hence move them over.
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.
2015-10-24util: split out escaping code into escape.[ch]Lennart Poettering
This really deserves its own file, given how much code this is now.
2015-09-30fileio: make get_status_field() more genericAaro Koskinen
All users of get_status_field() expect the field pattern to occur in the beginning of a line, and the delimiter is ':'. Hardcode this into the function, and also skip any whitespace before ':' to support fields in files like /proc/cpuinfo. Add support for returning the full field value (currently stops on first whitespace). Rename the function so it's easier to ensure all callers switch to new semantics.

2015-07-23process: an empty environment block should be returned as suchLennart Poettering
An empty env block is completely valid, hence return it as such, and don't turn it into an error.
2015-07-23process: return ESRCH when a PID is not valid anymoreLennart Poettering
so far, when we read something from /proc/$PID we would pass on the ENOENT from the kernel as error, if the process was missing. With this change we systematically convert this to ESRCH, which is the more appropriate error code, and what all the other glibc/syscalls like kill() use. All code that calls these functions should be fine with this change. In fact, one invocation of get_process_exe() in bus-creds.c already assumed ESRCH would be returned if a process is missing, and this assumption is now validated after the change.
