When these packages are released as part of Go 1.18,
Go 1.16 will no longer be supported, so we can remove
the +build tags in these files.
Ran go fix -fix=buildtag std cmd and then reverted the bootstrapDirs
as defined in src/cmd/dist/buildtool.go, which need to continue
to build with Go 1.4 for now.
Also reverted src/vendor and src/cmd/vendor, which will need
to be updated in their own repos first.
Manual changes in runtime/pprof/mprof_test.go to adjust line numbers.
For #41184.

Currently, the go resolver always send two DNS queries (A and AAAA) even
if tcp4/udp4/ip4 or tcp6/udp6/ip6 is used. This can cause unwanted
latencies when making IPv4-only or IPv6-only connections.
This change make go resolver aware of network parameter. Now, only one A
query is sent when tcp4/udp4/ip4 is used, and vice versa for
tcp6/udp6/ip6.
Fixes#45024

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)

The DNS code can start goroutines and not wait for them to complete.
This does no harm, but in tests this can cause a race condition with
the test hooks that are installed and unintalled around the tests.
Add a WaitGroup that tests of DNS can use to avoid the race.

When LookupIP is performing multiple subqueries, this option causes a
timeout/servfail affecting a single query to abort the whole operation,
instead of returning a partial (IPv4/IPv6-only) result.
Similarly, operations that walk the DNS search list will also abort when
encountering one of these errors.

Although calls to getaddrinfo can't be portably interrupted,
we still benefit from more granular resource management by

This change simplifies unnecessarily redundant error messages in tests.
There's no need to worry any more because package APIs now return
consistent, self-descriptive error values.
Alos renames ambiguous test functions and makes use of test tables.
