5b5ef07350 Add search domain to macos dns configuration
Stumbled upon this while debugging something else.
If we add search domain to our system configuration for
network DNS, then search domains work:

```
ping server1                                                                                                                                                                                    ~
PING server1.my.domain (10.123.3.1): 56 data bytes
64 bytes from 10.123.3.1
```

fb6af1971b Fix network DNS on macOS
It stopped working for ipv4 only networks in Monterey.
See #1696

We add some config like so to System Configuration

```
scutil
show State:/Network/Service/9bee8941b5xxxxxx/IPv4
<dictionary> {
  Addresses : <array> {
    0 : 10.2.1.36
  }
  InterfaceName : feth4823
  Router : 10.2.1.36
  ServerAddress : 127.0.0.1
}

```

22ab673480 Apply default route a different way - macOS
The original way we applied default route, by forking
0.0.0.0/0 into 0/1 and 128/1 works, but if mac os has any networking
hiccups -if you change SSIDs or sleep/wake- macos erases the system default route.
And then all networking on the computer is broken.

to summarize the new way:
allowDefault=1
```
sudo route delete default 192.168.82.1
sudo route add default 10.2.0.2
sudo route add -ifscope en1 default 192.168.82.1
```

gives us this routing table
```
Destination        Gateway            RT_IFA             Flags        Refs      Use    Mtu          Netif Expire    rtt(ms) rttvar(ms)
default            10.2.0.2           10.2.0.18          UGScg          90        1   2800       feth4823
default            192.168.82.1       192.168.82.217     UGScIg
```

allowDefault=0
```
sudo route delete default
sudo route delete -ifscope en1 default
sudo route add default 192.168.82.1
```

Notice the I flag, for -ifscope, on the physical default route.

route change does not seem to work reliably.

fix binding temporary ipv6 addresses on macos (#1910)
The check code wasn't running.

I don't know why !defined(TARGET_OS_IOS) would exclude code on
desktop macOS. I did a quick search and changed it to defined(TARGET_OS_MAC).
Not 100% sure what the most correct solution there is.

You can verify the old and new versions with

`ifconfig | grep temporary`

plus

`zerotier-cli info -j` -> listeningOn

a6742b7f82 Prevent shadowing VM routes as default route (macOS)
If you have a VM host like parallels, sometimes you get these link-local
default routes:

```
netstat -nrfinet | grep "default\|\/1"
0/1                10.2.0.12          UGScg        feth4823
default            192.168.82.1       UGScg             en1
0/1                192.168.82.1       UGScIg            en1
default            link#22            UCSIg       bridge101      !
128.0/1            10.2.0.12          UGSc         feth4823
128.0/1            192.168.82.1       UGScI             en1
```

(the link#22 one)

The _getRTEs function inclused these routes in the list it makes as like:

device: bridge101, target: 0.0.0.0/0

If it happens to be first in the list, bridge101 gets
selected as the default route.

Then Full Tunnel Mode doesn't work.

The other routes in the list are like:
device: en1 target: 192.168.1.0/24 via:  metric: 0 ifscope: 0
device: en1 target: 192.168.1.1/32 via:  metric: 0 ifscope: 0

We only need the device name from this, so either one will work.

Improve default route on macOS (#1680)
re: issue #1088
and probably: https://discuss.zerotier.com/t/default-route-issue-osx-monterey-m1/6974

// current zerotier.
// allow default adds two sets of routes.
```
netstat -rnfinet | grep "/1\|default" | sort
0/1                10.2.0.2           UGScg        feth4823
0/1                192.168.82.1       UGScIg            en7
128.0/1            10.2.0.2           UGSc         feth4823
128.0/1            192.168.82.1       UGScI             en7
default            192.168.82.1       UGScg             en7
```

Then, something chaotic happens eventually, and networking stops working.

// after patch
```
netstat -rnfinet | grep "/1\|default" | sort
0/1                10.2.0.2           UGScg        feth4823
128.0/1            10.2.0.2           UGSc         feth4823
default            192.168.82.1       UGScg             en7
```

After the change, I can still:
- use default route
- route to other subnets

I tested on high sierra through monterey
and on freebsd13.1

Merge pull request #1535 from zerotier/linux-route-metric

692a0e7ac2 Set a high metric on linux routes that have a via.
See issue #750.

zerotier doesn't currently set a metric on routes. Linux
takes this to mean "0", the highest priority.

Every comment in the issue is about routing between zerotier
and lan and how they conflict.

This quick change could fix this problem for most people.

The subnet route for the zerotier network, the one with no
via, is still 0 in this patch. Just the "via" routes get
higher metrics.
If for some reason, you needed your via routes to have
higher priority, you could use a prefix work-around:

192.168.1.0/25 via 10.147.17.1
192.168.1.128/25 via 10.147.17.1
