Lennart Poettering ece877d434 user-util: add new uid_is_system() helper 
This adds uid_is_system() and gid_is_system(), similar in style to
uid_is_dynamic(). That a helper like this is useful is illustrated by
the fact that test-condition.c didn't get the check right so far, which
this patch fixes.

Giuseppe Scrivano 36d854780c core: do not fail in a container if we can't use setgroups 
It might be blocked through /proc/PID/setgroups

Lennart Poettering be39ccf3a0 execute: move suppression of HOME=/ and SHELL=/bin/nologin into user-util.c 
This adds a new call get_user_creds_clean(), which is just like
get_user_creds() but returns NULL in the home/shell parameters if they contain
no useful information. This code previously lived in execute.c, but by
generalizing this we can reuse it in run.c.

Zbigniew Jędrzejewski-Szmek 61755fdae0 journald: do not create split journals for dynamic users 
Dynamic users should be treated like system users, and their logs
should end up in the main system journal.

Lennart Poettering e4631b48e1 sysusers: move various user credential validity checks to src/basic/ 
This way we can reuse them for validating User=/Group= settings in unit files
(to be added in a later commit).

Also, add some tests for them.

Lennart Poettering ccabee0d64 nspawn: make -U a tiny bit smarter 
With this change -U will turn on user namespacing only if the kernel actually
supports it and otherwise gracefully degrade to non-userns mode.

Daniel Mack b26fa1a2fb 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.

Thomas Hindoe Paaboel Andersen 71d35b6b55 tree-wide: sort includes in *.h 
This is a continuation of the previous include sort patch, which
only sorted for .c files.

Lennart Poettering e929bee09a util-lib: move take_password_lock() to user-util.[ch] 
Also, rename it take_etc_passwd_lock(), in order to make it more
expressive.

Lennart Poettering d02608170e 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(). Get rid of the former, in favour of the
latter, and while we are at it, rewrite it, to use getpwuid_r()
correctly, inside an allocation loop, as POSIX intended.
