Lennart Poettering 4f9ff96a55 conf-parser: return mtime in config_parse() and friends 
This is a follow-up for 9f83091e3c.

Instead of reading the mtime off the configuration files after reading,
let's do so before reading, but with the fd we read the data from. This
is not only cleaner (as it allows us to save one stat()), but also has
the benefit that we'll detect changes that happen while we read the
files.

This also reworks unit file drop-ins to use the common code for
determining drop-in mtime, instead of reading system clock for that.

Yu Watanabe 9f83091e3c network: also read mtime of drop-in configs 
Fixes #15521.

Lennart Poettering a0b191b705 condition: add ConditionEnvironment= 
Prompted by the discussions in #15180.

This is a bit more complex than I hoped, since for PID 1 we need to pass
in the synethetic environment block in we generate on demand.

Susant Sahani 3295a461b3 network: introduce ifb (Intermediate Functional Block) 
Intermediate Functional Block

The Intermediate Functional Block (ifb) pseudo network interface acts as a QoS concentrator for multiple different sources of traffic. Packets from or to other interfaces have to be redirected to it using the mirred action in order to be handled, regularly routed traffic will be dropped. This way, a single stack of qdiscs, classes and filters can be shared between multiple interfaces.

Here's a simple example to feed incoming traffic from multiple interfaces through a Stochastic Fairness Queue (sfq):

(1) # modprobe ifb
(2) # ip link set ifb0 up
(3) # tc qdisc add dev ifb0 root sfq

Zbigniew Jędrzejewski-Szmek 130b812f9d network: warn about unknown sections when parsing .netdev files 
Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1774242.
Now we'll emit the warning about unknown section [Netdev], making the issue
much easier to diagnose.

Susant Sahani 69c317a07f networkd: introduce netdev ipvtap 
This patch adds netdev ipvtap that is based on the
IP-VLAN network interface, called ipvtap. An ipvtap device can be created
in the same way as an ipvlan device, using 'kind ipvtap', and then accessed
using the tap user space interface.

Susant Sahani 81962db798 network: Introduce MACsec 
Media Access Control Security (MACsec) is an 802.1AE IEEE
industry-standard security technology that provides secure
communication for all traffic on Ethernet links.
MACsec provides point-to-point security on Ethernet links between
directly connected nodes and is capable of identifying and preventing
most security threats, including denial of service, intrusion,
man-in-the-middle, masquerading, passive wiretapping, and playback attacks.

Closes #5754

Yu Watanabe b519908cac network: do not abort execution when NetDev.Name= conflicts 
This also changes that .netdev files are loaded in ascending order.
Otherwise, when NetDev.ifname= setting conflicts with other .netdev file,
then .netdev file with large prefix number wins.
