681eb9cf2b man: generate configured paths in manpages
In particular, use /lib/systemd instead of /usr/lib/systemd in distributions
like Debian which still have not adopted a /usr merge setup.

Use XML entities from man/custom-entities.ent to replace configured paths while
doing XSLT processing of the original XML files. There was precedent of some
files (such as systemd.generator.xml) which were already using this approach.

This addresses most of the (manual) fixes from this patch:
http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/patches/Fix-paths-in-man-pages.patch?h=experimental-220

The idea of using generic XML entities was presented here:
http://lists.freedesktop.org/archives/systemd-devel/2015-May/032240.html

This patch solves almost all the issues, with the exception of:
- Path to /bin/mount and /bin/umount.
- Generic statements about preference of /lib over /etc.

These will be handled separately by follow up patches.

Tested:
- With default configure settings, ran "make install" to two separate
  directories and compared the output to confirm they matched exactly.
- Used a set of configure flags including $CONFFLAGS from Debian:
  http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/rules
  Installed the tree and confirmed the paths use /lib/systemd instead of
  /usr/lib/systemd and that no other unexpected differences exist.
- Confirmed that `make distcheck` still passes.

505c5f6de1 networkd: don't touch global forwarding setting
This reverts commit 43c6d5abac
(and a small part of 4046d8361c)

It turns out we don't actually need to set the global ip_forward setting.
The only relevant setting is the one on each interface.

What the global toggle actually does is switch forwarding on/off for all
currently present interfaces and change the default for new ones.

That means that by setting the global ip_forward we

  - Introduce a race condition, because if the interface with IPForward=yes
    is brought up after one with IPForward=no, both will have forwarding
    enabled, because the global switch turns it on for all interfaces.
    If the other interface comes up first networkd correctly sets forward=0
    and it doesn't get overridden.

  - Change the forwarding setting for interfaces that networkd is not
    configured to touch, even if the user disabled forwarding via sysctl,
    either globally or per-interface

As forwarding works fine without this, as long as all relevant interfacest
individually set IPForward=yes:  just drop it

This means that non-networkd interfaces use the global default while
networkd interfaces default to off if IPForward isn't given.

5a8bcb674f networkd: add minimal IP forwarding and masquerading support to .network files
This adds two new settings to networkd's .network files:
IPForwarding=yes and IPMasquerade=yes. The former controls the
"forwarding" sysctl setting of the interface, thus controlling whether
IP forwarding shall be enabled on the specific interface. The latter
controls whether a firewall rule shall be installed that exposes traffic
coming from the interface as coming from the local host to all other
interfaces.

This also enables both options by default for container network
interfaces, thus making "systemd-nspawn --network-veth" have network
connectivity out of the box.

ba17915457 networkd: ipv4ll - configure link-local address independently of DHCPv4
This changes the behavior when both DHCPv4 and IPv4LL are enabled. Before,
we would disable IPv4LL when we got a DHCPv4 lease and enable it if the
lease was lost.

Now we just always set up both, if both are enabled, but the DHCPv4
addresses and routes will always take precedence due to their metric
and scope.

f5de5b0020 sd-dhcp-client: make request broadcasts opt-in
It appears there is no good way to decide whether or not broadcasts should be enabled,
there is hardware that must have broadcast, and there are networks that only allow
unicast. So we give up and make this configurable.

By default, unicast is used, but if the kernel were to inform us abotu certain
interfaces requiring broadcast, we could change this to opt-in by default in
those cases.

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.
