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

util-lib: move take_password_lock() to user-util.[ch] Also, rename it take_etc_passwd_lock(), in order to make it more expressive.

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

user-util: never hand out or accept invalid UIDs libc isn't that strict, but it's a good idea if we are, to not create confusion around invalid user ids.

util: remove lookup_uid(), replace by uid_to_name() So far we had two pretty much identical calls in user-util.[ch]: lookup_uid() and uid_to_name().

user-util: simplify uid parsing a bit

util-lib: split out user/group/uid/gid calls into user-util.[ch]
