21ed31e33a wgengine/filter: use NewContainsIPFunc for Srcs matches 
NewContainsIPFunc returns a contains matcher optimized for its
input. Use that instead of what this did before, always doing a test
over each of a list of netip.Prefixes.

1ecc16da5f tailcfg,ipn/ipnlocal,wgengine: add values to PeerCapabilities 
Define PeerCapabilty and PeerCapMap as the new way of sending down
inter-peer capability information.

Previously, this was unstructured and you could only send down strings
which got too limiting for certain usecases. Instead add the ability
to send down raw JSON messages that are opaque to Tailscale but provide
the applications to define them however they wish.

Also update accessors to use the new values.

Updates #4217

71029cea2d all: update copyright and license headers 
This updates all source files to use a new standard header for copyright
and license declaration.  Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.

This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

    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.

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.

wgengine/filter: preallocate some hot slices in MatchesFromFilterRules (#4672) 
Profiling identified this as a fairly hot path for growing a slice.

Given this is only used in control & when a new packet filter is received, this shouldnt be hot in the client.

25df067dd0 all: adapt to opaque netaddr types 
This commit is a mishmash of automated edits using gofmt:

gofmt -r 'netaddr.IPPort{IP: a, Port: b} -> netaddr.IPPortFrom(a, b)' -w .
gofmt -r 'netaddr.IPPrefix{IP: a, Port: b} -> netaddr.IPPrefixFrom(a, b)' -w .

gofmt -r 'a.IP.Is4 -> a.IP().Is4' -w .
gofmt -r 'a.IP.As16 -> a.IP().As16' -w .
gofmt -r 'a.IP.Is6 -> a.IP().Is6' -w .
gofmt -r 'a.IP.As4 -> a.IP().As4' -w .
gofmt -r 'a.IP.String -> a.IP().String' -w .

And regexps:

\w*(.*)\.Port = (.*)  ->  $1 = $1.WithPort($2)
\w*(.*)\.IP = (.*)  ->  $1 = $1.WithIP($2)

And lots of manual fixups.
