8e38570ebe tree-wide: htonl() is weird, let's use htobe32() instead (#3538)
Super-important change, yeah!

2817157bb7 resolved: support IPv6 DNS servers on the local link
Make sure we can parse DNS server addresses that use the "zone id" syntax for
local link addresses, i.e. "fe80::c256:27ff:febb:12f%wlp3s0", when reading
/etc/resolv.conf.

Also make sure we spit this out correctly again when writing /etc/resolv.conf
and via the bus.

Fixes: #3359

ef76dff225 util-lib: add new ifname_valid() call that validates interface names
Make use of this in nspawn at a couple of places. A later commit should port
more code over to this, including networkd.

fc2fffe770 tree-wide: introduce new SOCKADDR_UN_LEN() macro, and use it everywhere
The macro determines the right length of a AF_UNIX "struct sockaddr_un" to pass to
connect() or bind(). It automatically figures out if the socket refers to an
abstract namespace socket, or a socket in the file system, and properly handles
the full length of the path field.

This macro is not only safer, but also simpler to use, than the usual
offsetof() + strlen() logic.

4ebc62ec87 test: fix failing test-socket-util when running with ipv6.disable=1 kernel param
The ability to use inet_pton(AF_INET6, ...) doesn't depend on kernel
ipv6 support (inet_pton is a pure libc function), so make ipv6 address
parsing tests unconditional.

3ffd4af220 util-lib: split out fd-related operations into fd-util.[ch]
There are more than enough to deserve their own .c file, hence move them
over.

07630cea1f util-lib: split our string related calls from util.[ch] into its own file 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.

da927ba997 treewide: no need to negate errno for log_*_errno()
It corrrectly handles both positive and negative errno values.

0a1beeb642 treewide: auto-convert the simple cases to log_*_errno()
As a followup to 086891e5c1 "log: add an "error" parameter to all
low-level logging calls and intrdouce log_error_errno() as log calls
that take error numbers", use sed to convert the simple cases to use
the new macros:

find . -name '*.[ch]' | xargs sed -r -i -e \
's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/'

Multi-line log_*() invocations are not covered.
And we also should add log_unit_*_errno().

3b653205cf shared: split out in_addr related calls from socket-util.[ch] into its private in-addr-util.[ch]
These are enough calls for a new file, and they are sufficiently
different from the sockaddr-related calls, hence let's split this out.
