Brad FitzpatrickandBrad Fitzpatrick a12aad6b47 all: convert more code to use net/netip directly 
perl -i -npe 's,netaddr.IPPrefixFrom,netip.PrefixFrom,' $(git grep -l -F netaddr.)
    perl -i -npe 's,netaddr.IPPortFrom,netip.AddrPortFrom,' $(git grep -l -F netaddr. )
    perl -i -npe 's,netaddr.IPPrefix,netip.Prefix,g' $(git grep -l -F netaddr. )
    perl -i -npe 's,netaddr.IPPort,netip.AddrPort,g' $(git grep -l -F netaddr. )
    perl -i -npe 's,netaddr.IP\b,netip.Addr,g' $(git grep -l -F netaddr. )
    perl -i -npe 's,netaddr.IPv6Raw\b,netip.AddrFrom16,g' $(git grep -l -F netaddr. )
    goimports -w .

Then delete some stuff from the net/netaddr shim package which is no
longer neeed.

Brad FitzpatrickandBrad Fitzpatrick 6a396731eb all: use various net/netip parse funcs directly 
Mechanical change with perl+goimports.

Changed {Must,}Parse{IP,IPPrefix,IPPort} to their netip variants, then
goimports -d .

Finally, removed the net/netaddr wrappers, to prevent future use.

Maisem AliandMaisem Ali b2f269d5b7 net/dnsfallback: do not attempt lookups of IPs. 
Currently if the passed in host is an IP, Lookup still attempts to
resolve it with a dns server. This makes it just return the IP directly.

David AndersonandDave Anderson 2a412ac9ee .github/workflows: work around golang/go#51629 
Incidentally, simplify the go generate CI workflow, by
marking the dnsfallback update non-hermetic (so CI will
skip it) rather than manually filter it out of `go list`.

Joe TsaiandBrad Fitzpatrick 9af27ba829 cmd/cloner: mangle "go:generate" in cloner.go 
The "go generate" command blindly looks for "//go:generate" anywhere
in the file regardless of whether it is truly a comment.
Prevent this false positive in cloner.go by mangling the string
to look less like "//go:generate".

Brad FitzpatrickandBrad Fitzpatrick 7cf8ec8108 net/tlsdial: bake in LetsEncrypt's ISRG Root X1 root 
We still try the host's x509 roots first, but if that fails (like if
the host is old), we fall back to using LetsEncrypt's root and
retrying with that.

tlsdial was used in the three main places: logs, control, DERP. But it
was missing in dnsfallback. So added it there too, so we can run fine
now on a machine with no DNS config and no root CAs configured.

Also, move SSLKEYLOGFILE support out of DERP. tlsdial is the logical place
for that support.

Fixes #1609

Brad Fitzpatrick 10d7c2583c net/dnsfallback: don't depend on derpmap.Prod 
Move derpmap.Prod to a static JSON file (go:generate'd) instead,
to make its role explicit. And add a TODO about making dnsfallback
use an update-over-time DERP map file instead of a baked-in one.
