Add linknames for most modules with ≥50 dependents.
Add linknames for a few other modules that we know
are important but are below 50.
Remove linknames from badlinkname.go that do not merit
inclusion (very small number of dependents).
We can add them back later if the need arises.
Fixes #67401. (For now.)

DragonFly BSD and OpenBSD do not implement mapping IPv4 addresses to
the IPv6 address space, and a runtime check can be avoided.
As the IP stack capabilities probe was only being called from
supportsIPv4map to check for this support, the OS-specific handling
can be added to this function rather than continuing to run the probe.

Unlike the go resolver, the existing cgo resolver exchanges both DNS A
and AAAA RR queries unconditionally and causes unreasonable connection
setup latencies to applications using the cgo resolver.
This change adds new argument (`network`) in all functions through the
series of calls: from Resolver.internetAddrList to cgoLookupIPCNAME.
Benefit: no redundant DNS calls if certain IP version is used IPv4/IPv6
(no `AAAA` DNS requests if used tcp4, udp4, ip4 network. And vice
versa: no `A` DNS requests if used tcp6, udp6, ip6 network)

ResolveTCPAddr, ResolveUDPAddr, and ResolveIPAddr return at most one
address. When given a name like "golang.org" to resolve that might
have more than 1 address, the net package has historically preferred
IPv4 addresses, with the assumption that many users don't yet have
IPv6 connectivity and randomly selecting between an IPv4 address and
an IPv6 address at runtime wouldn't be a good experience for IPv4-only
users.
In CL 45088 (78cf0e56) I modified the resolution of the
unspecified/empty address to internally resolve to both IPv6 "::" and
0.0.0.0 to fix issue #18806.
That code has 3 other callers I hadn't considered, though: the
Resolve*Addr functions. Since they preferred IPv4, any Resolve*Addr of
"[::]:port" or "::" (for ResolveIPAddr) would internally resolve both
"::" and 0.0.0.0 and then prefer 0.0.0.0, even though the user was
looking up an IPv6 literal.
Add tests and fix it, not by undoing the fix to #18806 but by
selecting the preference function for Resolve*Addr more explicitly: we
still prefer IPv4, but if the address being looked up was an IPv6
literal, prefer IPv6.
The tests are skipped on machines without IPv6.
Fixes #20911

Some machines can be configured (or came/come configured) in such a
state that IPv6 only half works: you can bind on [::]:n but not
connect back to it.
This implements a fallback such that it's guaranteed that this pattern
works:
ln, err := Listen("tcp", ":0")
...
addr := ln.Addr().String() // "[::]:n"
c, err := Dial("tcp", addr)
... which is also now tested. It will first try to dial "[::]:n", as
before, but if that dial fails, it will also try "0.0.0.0:n".

The net package uses various textual representations for network
identifiers and locators on the Internet protocol suite as API.
In fact, the representations are the composition of subset of multple
RFCs: RFC 3986, RFC 4007, RFC 4632, RFC 4291 and RFC 5952.
RFC 4007 describes guidelines for the use of textual representation of
IPv6 addressing/routing scope zone and doesn't prohibit the format for
implementation dependent purposes, as in, specifying a literal IPv6
address and its connected region of routing topology as application
user interface. However, a non-literal IPv6 address, for example, a
host name, with a zone enclosed in square brackets confuses us because
a zone is basically for non-global IPv6 addresses and a pair of square
brackets is used as a set of delimiters between a literal IPv6 address
and a service name or transport port number.
To mitigate such confusion, this change makes JoinHostPort not enclose
non-literal IPv6 addresses in square brackets and SplitHostPort accept
the form "host%zone:port" to recommend that anything enclosed in
square brackets should be a literal IPv6 address.
Before this change:
JoinHostPort("name%zone", "80") = "[name%zone]:80"
JoinHostPort("[::1%zone]", "80") = "[::1%zone]:80"
SplitHostPort("name%zone:80") = "", "", "address name%zone:80: missing brackets in address"
SplitHostPort("[name%zone]:80") = "name%zone", "80", nil
SplitHostPort("[::1%zone]:80") = "::1%zone", "80", nil
After this change:
JoinHostPort("name%zone", "80") = "name%zone:80"
JoinHostPort("[::1%zone]", "80") = "[::1%zone]:80"
SplitHostPort("name%zone:80") = "name%zone", "80", nil
SplitHostPort("[name%zone]:80") = "name%zone", "80", nil // for backwards compatibility
SplitHostPort("[::1%zone]:80") = "::1%zone", "80", nil
Also updates docs and test cases on SplitHostPort and JoinHostPort for
clarification.

The restrictions were already being applied to the IP addresses
received from the host resolver. Apply the same restrictions to
literal IP addresses not passed to the host resolver.
For example, ResolveTCPAddr("tcp4", "[2001:db8::1]:http") used
to succeed and now does not (that's not an IPv4 address).
Perhaps a bit surprisingly,
ResolveTCPAddr("tcp4", "[::ffff:127.0.0.1]:http") succeeds,
behaving identically to ResolveTCPAddr("tcp4", "127.0.0.1:http"), and
ResolveTCPAddr("tcp6", "[::ffff:127.0.0.1]:http") fails,
behaving identically to ResolveTCPAddr("tcp6", "127.0.0.1:http").
Even so, it seems right to match (by reusing) the existing filtering
as applied to addresses resolved by the host C library.
If anyone can make a strong argument for changing the filtering
of IPv4-inside-IPv6 addresses, the fix can be applied to all
the code paths in a separate CL.
Fixes #14037.

The new Resolver type (a struct) has 9 Lookup methods, all taking a
context.Context.
There's now a new DefaultResolver global, like http's
DefaultTransport and DefaultClient.
net.Dialer now has an optional Resolver field to set the Resolver.
This also does finishes some resolver cleanup internally, deleting
lookupIPMerge and renaming lookupIPContext into Resolver.LookupIPAddr.
The Resolver currently doesn't let you tweak much, but it's a struct
specifically so we can add knobs in the future. Currently I just added
a bool to force the pure Go resolver. In the future we could let
people provide an interface to implement the methods, or add a Timeout
time.Duration, which would wrap all provided contexts in a
context.WithTimeout.

These a series of changes fix inconsistent errors on the package net
APIs. Now almost all the APIs return OpError as a common error type
except Lookup, Resolve and Parse APIs. The Lookup, Resolve and Parse
APIs return more specific errors such as DNSError, AddrError or
ParseError.
An OpError may contain nested error information. For example, Dial may
return an OpError containing a DNSError, AddrError, unexposed type/value
or other package's type/value like the following:
OpError{/* dial info */, Err: &DNSError{}}
OpError{/* dial info */, Err: &AddrError{}}
OpError{/* dial info */, Err: <unexposed type or value>}
OpError{/* dial info */, Err: <other package's type or value>}
and Read and Write may return an OpError containing other OpError when
an application uses io.Copy or similar:
OpError{/* for io.Reader */, Err: &OpError{/* for io.Writer */}}
When an endpoint is created for connection-oriented byte-stream
protocols, Read may return an io.EOF when the connection is closed by
remote endpoint.

Remove the "netaddr" type, which ambiguously represented either one
address, or a list of addresses. Instead, use "addrList" wherever
multiple addresses are supported.
The "first" method returns the first address matching some condition
(e.g. "is it IPv4?"), primarily to support legacy code that can't handle
multiple addresses.
The "partition" method splits an addrList into two categories, as
defined by some strategy function. This is useful for implementing
Happy Eyeballs, and similar two-channel algorithms.
Finally, internetAddrList (formerly resolveInternetAddr) no longer
mangles the ordering defined by getaddrinfo. In the future, this may
be used by a sequential Dial implementation.
