cryptsetup: don't add unit dependency on /dev/null devices when it is listed as password file

As special magic, don't create device dependencies for /dev/null. Of
course, there might be similar devices we might want to include, but
given that none of them really make sense to specify as password source
there's really no point in checking for anything else here.

coredump: retrieve comm information from /proc

Kernel mangles comm information in an irreversible way when comm
constains repeated spaces. Retrieve comm information from /proc, and
only fallback to the information provided on the commandline when
retrieving information from /proc fails.

Add exe information to the list of saved xattr.

nspawn: create essential base directories at system bootup

This allows us to bootup a rootfs with a /usr directory only.
sd-dhcp-client: return NULL from _unref() like the other sd-* libraries

Let's keep this behavior consistent across our libraries.

In order to keep the refcounting working, a DONT_DESTROY macro similar
to the one in sd-bus was introduced.
