Some callbacks may run twice, e.g., lag_gen_ports(). Check if the link
already exists, and is the same, then we can exit silently. However, in
case the link exists and does *not* point to the same target, we log an
error with current target for the post mortem.

The speed/duplex of a virtio interface is not eenforced in any way. The
driver initializes them to unknown/unkown:
https://github.com/torvalds/linux/blob/dccbe2047a5b0859de24bf463dae9eeea8e01c1e/drivers/net/virtio_net.c#L5375-L5381
It is however possible to set them since there are kernel subsystems
that rely on them, e.g., miimon in the bond driver, which in turn is
required for use with the 802.3ad (lacp) mode.
If we do not initialize speed/duplex the miimon will complain in the log
on virtual test systems every second:
Dec 13 22:34:08 laggy kernel: lag0: (slave e1): failed to get link speed/duplex

The management of custom-phys-address was made more complicated by the
fact that physical interfaces require restoring the permanent address
when a custom setting is removed.
Simplify this by moving the restoration to the delete path, so we only
have to worry about if there is a custom mac or not during interface
setup.
Also:
- Fix some legacy naming on *_gen() functions
- Fix custom-phys-address on dummy interfaces
Fix#938
Before this change, interface dependencies were only setup when
interfaces were created. This led to problems in flows like this:
1.
configure
set interface br0
set interface br0.10
leave
2.
configure
set interface dummy0
leave
2.
configure
no interface br0
no interface br0.10
leave
Since neither br0 nor br0.10 was created in (2), no dependencies were
setup. Because of that, when the deletion scripts from generation (2)
are generated when entering (3), dagger is free to execute them in any
order. This means that it may choose to remove br0 before br0.10,
which will mean that br0.10 is already gone when we try to remove it.
Therefore, make sure that we generate the full dependency graph on
every iteration.
Also, get rid of the need to keep on-disk state for VETH pairs, and
use the name as a descriminator for which side to create/delete.
With the new iftype enum, we see that configuring an existing dummy or
gre interface types was wrongly classified as an error rather than as
a NOP.
Example, before this change, this was OK:
configure
set interface foo
set interface foo ipv4 address 10.0.0.1 prefix-length 24
leave
However, this was not:
configure
set interface foo
+leave
+configure
set interface foo ipv4 address 10.0.0.1 prefix-length 24
leave
+<KABOOM>
This has multiple advantages:
- Less chances of typos is repeated "infix-if-type:foo" strings
scattered throughout the code
- We can lean on GCC's `-Werror=switch` to make sure that iface
specific logic always handles all types (which was not always the
case - see follow-up commits)
- We can potentially create a `struct afspec_ops` in the future, which
could then be indexed by this enum
The only interfaces that would be in difs, but not in cifs, are
deleted interfaces. But these will be removed from the exit action of
the previous generation, and will never be referenced in the new
generation.
Pointer authentication emulation is expensive. By default, QEMU use the
standard cryptographic algorithm (QARMA5), which is very time consuming.
This commit switches to the fast implementation.

Instead of encoding hex data in regular strings, using an 'id:' prefix,
or guessing based on pattern in C code, we have decided for a breaking
change in the DHCP client model.
This commit introduces string and hex values for client-id in the models
for both DHCP client and server. The *breaking* part of the changes are
strictly related to how a user pass binary data as colon-separated hex
digits. The dedicated leaf node `client-id` is now reserved for string
values and the generic `list option` can be used to input user defined
string or hex values. Even non-conformant client-id options can now be
encoded. All described in detail in infix-dhcp-client.yang
The server model has been updated to be able to send generic options in
hex format, and the static host lease matcher for client-id now require
a 'str' or 'hex' modifier.
Note: dnsmasq is RFC compliant and will not match non-conforming option
61 (client-id) even though the client can send such payload.
To increase test coverage, the server_host test has been updated to
check both string and hex client-id. Matching on hostname is already
covered by other test(s).

With support for dns resolver in place, the ietf-system output needs to
be complemented with additional data collected from both the dnsmasq and
openresolv subsystems.

- dnsmasq:
- allow listening to all interfaces again to serve DHCP leases
- disable most of the default DHCP options, keep broadcast and
netmask because when dnsmasq can infer these they are better
than breaking networking for clients -- note, they can still
be overridden from global/subnet/host scope -- and for relay
setups they need to be supplied anyway
- confd:
- drop per-interface dnsmasq, although practical for many use-cases,
having a per-subnet focused server means improved integration with
future stand-alone dhcp relay setup
- implement suggested, simplified, yang model
