networkd: rework headers to avoid circular includes

Header files were organized in a way where the includer would add various
typedefs used by the includee before including it, resulting in a tangled
web of dependencies between files.

Replace this with the following logic:

          networkd.h
         /          \
networkd-link.h      \
networkd-ipv4ll.h--\__\
networkd-fdb.h         \
networkd-network.h    netword-netdev-*.h
networkd-route.h           \
                      networkd-netdev.h

If a pointer to a structure defined in a different header file is needed,
use a typedef line instead of including the whole header.
