sd-network: drop get_ifindices

People should use rtnl for this, and then only query sd-network by the ifindices it finds.
networkd: netdev - split NetDev struct into per-kind structs

Similarly to how unit types work.
sd-rtnl: uncomment bond rtnl constants
networkd: add support for bond transmit hash policy

This patch adds support  the transmit hash policy to use
for slave selection in balance-xor, 802.3ad, and tlb modes

layer2, layer3+4, layer2+3, encap3+4, encap3+4

Added:
1. BondXmitHashPolicy
2. conf param TransmitHashPolicy

Test conf:
[NetDev]
Name=bond1
Kind=bond

[Bond]
Mode=802.3ad
TransmitHashPolicy=layer2+3

test output:
cat /proc/net/bonding/bond1
Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011)

Bonding Mode: IEEE 802.3ad Dynamic link aggregation
Transmit Hash Policy: layer2+3 (2)
MII Status: up
MII Polling Interval (ms): 0
Up Delay (ms): 0
Down Delay (ms): 0

802.3ad info
LACP rate: slow
Min links: 0
Aggregator selection policy (ad_select): stable
bond bond1 has no active aggregator

[tomegun: dropped bond_ prefix from new Bond variable, drop repeated man-page section]
networkd: bond add support for lacp rate

LacpduTransmitRate
option specifies the rate in which link partner to transmit
LACPDU packets in 802.3ad mode.  Possible values
slow : Request partner to transmit LACPDUs every 30 seconds
fast : Request partner to transmit LACPDUs every 1 second
The default is slow.

chages:
1. Added enum bond_lacp_rate_table
2. gperf LacpduTransmitRate

[tomegun: renamed from LacpduTransmitRate to LACPTransmitRate, manpage fixes and
dropped bond_ prefix from variables]
networkd: add support for bond options

The following bond options are supported by this patch.

MIIMonitorSec:
Specifies the frequency in milli-seconds that MII link
monitoring will occur.

UpDelaySec:
Specifies the delay time in milli-seconds to enable a link
after a link up status has been detected.

DownDelaySec:
Specifies the delay time in milli-seconds to disable a link
after a link failure has been detected.

changes:
1. Added gconf variables.
2. man page

sysusers: fix selinux context of backup files

Also, fix fopen_temporary_label to set proper context. By chance,
all users so far used the same context, so the error didn't matter.

Also, check return value from label_init().

Merge systemd-verify with systemd-analyze
shell-completion: systemd-analyze verify, systemctl link

Some zsh completion helpers were not installed, so completion
was broken.

Add systemd-analyze verify. Make systemctl link complete only
unit names.
