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.
