Susant Sahani a6f1848a23 network: Allow to configure addr_gen_mode 
Defines how link-local and autoconf addresses are generated.

	0: generate address based on EUI64 (default)
	1: do no generate a link-local address, use EUI64 for addresses generated
	   from autoconf
	2: generate stable privacy addresses, using the secret from
	   stable_secret (RFC7217)
	3: generate stable privacy addresses, using a random secret if unset

Zbigniew Jędrzejewski-Szmek e0c17a7d1b bus-message: fix negative offset with ~empty message 
In the linked reproducer, m->fields_size == 0, and we calculate ri == -1, which
of course doesn't end well. Skip the whole calculation if m->fields_size == 0,
and also check that we don't go negative even if it is non-zero.

Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=19446 and #15583.

David Wood 7354900ddd network: Fix split in `SendOption=` on client and server 
When specifying `DHCPv4.SendOption=`, it is used by systemd-networkd to
set the value of that option within the DHCP request that is sent out.
This differs to setting `DHCPServer.SendOption=`, which will place all
the options together as suboptions into the vendor-specific information
(code 43) option.

This commit adds two new config options, `DHCPv4.SendVendorOption=` and
`DHCPServer.SendVendorOption=`. These both have the behaviour of the old
`DHCPServer.SendOption=` flag, and set the value of the suboption in the
vendor-specific information option.

The behaviour of `DHCPServer.SendOption=` is then changed to reflect
that of `DHCPv4.SendOption=`. It will set the value of the corresponding
option in the DHCP request.
