man: include the target name when linking to man pages in html output
Links like http://www.freedesktop.org/software/systemd/man/systemd.socket.html
are changed to http://www.freedesktop.org/software/systemd/man/systemd.socket.html#Accept=.
This implementation is quick & dirty, and misses various corner
cases. A fairly important one is that when a few directives share the
same anchor (which happens when multiple directives are described in
the same paragraph), generated links for everything except the first
one link to an invalid anchor. Another shortcoming is that the
formatting does not use the proper generateID machinery, so the anchor
name could be wrong in some cases. But it seems to work for a large
percentage of links, so seems to be an improvement in usability. When
the anchor is missing, we land at the top of the page, which is the
same as before. If the anchor were to point to different spot, this
would be more confusing... Not sure if that ever happens. Anyway, the
user should be able to recover from landing on the wrong place in the
page.
We already have a state RUNNING and EXITING when we dispatch regular and
exit callbacks. Let's introduce a new state called PREPARING that is
active while we invoke preparation callbacks. This way we have a state
each for all three kinds of event handlers.
The states are currently not documented, hence let's add a new state to
the end, before we start documenting this.
sd-event: make _ref() calls NOPs when NULL is passed to them
Let's make _ref() calls happy when NULL is passed to them, and simply
return NULL without any assertion logic. This makes them nicely
symmetric to the _unref() calls which also are happy to take NULL and
become NOPs then.

test: remove wrong endianess conversion in test-siphash24
Commit 933f9caee changed the returned result of siphash24_finalize() from
little-endian to native. Follow suit in test-siphash24 and drop the endianess
conversion there as well, so that this succeeds on big-endian machines again.

sd-ndisc: drop RA packets from non-link-local addresses
See https://tools.ietf.org/html/rfc4861#section-4.2. Some routers (dnsmasq) will send packets
from global addresses, which would break the default route setup, so ignore those.
resolved: shortcut lookups names in the local zone
Previously, we'd always generate a packet on the wire, even for names
that are within our local zone. Shortcut this, and always check the
local zone first. This should minimize generated traffic and improve
security.
resolved: simplify dns zone logic: take a single key when looking up entries
Instead of taking a DnsQuestion object (i.e. an array of keys) only take
a single key. This simplifies things a bit, and as DNS/LLMNR require a
single question per query message was unnecessary anyway.
This mimics a similar change that was done a while ago for the dns cache
logic.
journald: turn ForwardToSyslog= off by default
After all, rsyslog and friends nowadays read their data directly from
the journal, hence the forwarding is unnecessary in most cases.
core: add RemainAfterElapse= setting to timer units
Previously, after a timer unit elapsed we'd leave it around for good,
which has the nice benefit that starting a timer that shall trigger at a
specific point in time multiple times will only result in one trigger
instead of possibly many. With this change a new option
RemainAfterElapse= is added. It defaults to "true", to mimic the old
behaviour. If set to "false" timer units will be unloaded after they
elapsed. This is specifically useful for transient timer units.
run: when automatically generating names for transient units, use unique bus ID, fallback to random
Previously we used the process ID to generate transient unit names.
However, that is problematic as PIDs get reused easily, and applying
them to remote systems makes little sense.
Fortunately, each bus peer gets a unique, non-reusable ID assigned when
attaching to a bus, hence let's use that, if we can. In some cases we
cannot however, because we connect directly to PID's private socket, and
thus are not a proper bus peer with a unique ID. In that case generate a
random UUID to name the unit after.
core: dispatch load queue each time we set up a transient units
manager_load_unit() will dispatch the load queue anyway, but let's make
sure we also dispatch it immediately, after truning a unit into a
transient one and loading the properties from the message. That way the
know about the validity of the unit before we begin processing the next
auxiliary unit.
core: move check whether a unit is suitable to become transient into unit.c
Lets introduce unit_is_pristine() that verifies whether a unit is
suitable to become a transient unit, by checking that it is no
referenced yet and has no data on disk assigned.
core: generate nice error messages for auxiliary transient units, too
Let's move the validation checks into the loop that sets up the main and
auxiliary transient units, so that we can generate pretty error messages
for all units a transient unit transaction generates, not just for the
main unit.

networkd: ndisc - consider configured on timeout
Don't block indefinitely, when control has been passed on from NDisc to DHCPv6.
In this case there is likely no IPv6 support on the local link, so otherwise
this would block indefinitely.
libsystemd-network: add support for "Client FQDN" DHCP option
This adds support for the Client Fully Qualified Domain Name (FQDN)
option [RFC 4702] to libsystemd-network. The option can be used to
exchange information about a DHCPv4 client's fully qualified domain
name and about responsibility for updating the DNS RR related to the
client's address assignment.
Other popular DHCP clients (dhclient, dhcpcd) support this option and
it would be useful to have it in networkd too.

networkd: ndisc - always configure dhcp6 client
The ndisc client may trigger the dhcpv6 client to be started (this is the common case),
so we should allocate the dhcpv6 client whenever we allocate the ndisc one.
