Let's not leak details from src/shared and src/libsystemd into
src/basic, even though you can't actually do anything useful with
just forward declarations from src/shared.
The sd-forward.h header is put in src/libsystemd/sd-common as we
don't have a directory for shared internal headers for libsystemd
yet.
Let's also rename forward.h to basic-forward.h to keep things
self-explanatory.
This code seems to not be used anywhere at all, so let's drop it.

This fixes the following error:
---
systemd-networkd[1449490]: ip6tnl0: Saved hardware address: 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00
systemd-networkd[1449490]: ip6tnl0: Failed to manage link by its new hardware address, ignoring: File exists

It seems to, but I was a bit incredulous… The comment is adjusted to match
the standard.
The trick with a temporary buffer is neat. I wasn't sure if it is valid, but
the standard says so. The test really tests that we are reading the rules right
and that the compiler doesn't do anythign strange or emit an unexpected
warning.
Hardware addresses come in various shapes and sizes, these new functions
and accomapying data structures account for that instead of hard-coding
a hardware address to the 6 bytes of an ethernet MAC.
This part of the copyright blurb stems from the GPL use recommendations:
https://www.gnu.org/licenses/gpl-howto.en.html
The concept appears to originate in times where version control was per
file, instead of per tree, and was a way to glue the files together.
Ultimately, we nowadays don't live in that world anymore, and this
information is entirely useless anyway, as people are very welcome to
copy these files into any projects they like, and they shouldn't have to
change bits that are part of our copyright header for that.
hence, let's just get rid of this old cruft, and shorten our codebase a
bit.
Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.
I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.
This isn't quite symmetrical to in_addr_from_string() because it also returns
an offset indicating how much of the string was consumed by the matched
pattern. This offset reporting is needed for either of the following use
cases:
* verifying the lack of trailing garbage after such an address
* parsing subsequent data from the same string
