615c1467c8 sd-dhcp-client: add support for FORCERENEW
This partially implements RFC3203. Note that we are not fully compliant as we do not
support authentication.

edb85f0d8d networkd: dhcp add vendor class indentifier option 60
Vendor Class Identifier be used by DHCP clients to identify
their vendor type and configuration. When using this option,
vendors can define their own specific identifier values, such
as to convey a particular hardware or operating system
configuration or other identifying information.

Vendor-specified DHCP options—features that let administrators assign
separate options to clients with similar configuration requirements.
For example, if DHCP-aware clients for example we want to separate
different gateway and option for different set of people
(dev/test/hr/finance) in a org or devices for example web/database
servers or let's say in a embedded device etc and require a different
default gateway or DNS server than the rest of clients.

23289745d7 sd-dhcp: rely on FIONREAD working
This fallback will anyway never get tested, so rip it out.

20b958bf15 sd-dhcp: refactor dhcp_option_append
Store a pointer to the options in the DHCPMessage struct, and pass
this together with an offset around, rather than a uint8_t**.

This avoids us having to (re)compute the pointer; and changes
dhcp_option_append from adjusting both the pointer to the next
option and the remaining size of the options, to just adjusting
the current offset.

This makes the code a bit simpler to follow IMHO, but there should
be no functional change.

781ca7a13f sd-dhcp-client: Add an explicit stop state for the DHCP client
Add an explicit stop state for the DHCP client so that the library
user can issue a stop at any time the callback has been called.
When returning from the callback, check also the stop state and
stop any further DHCP processing.

3b7ca119fd sd-dhcp-client: move magic cookie into DHCPMessage struct
Also move the checking of it to the main message handler, rather than the
options parser.

Fix a bug, so we now drop the packet if any of the magic bytes don't match.
Before we used to only drop the packet if they were all wrong.

fe8db0c5ee sd-network: add new library
This is similar to sd-login, but exposes the state of networkd rather than logind.

Include it in libsystemd-dhcp and rename it to libsystemd-network.
