4b3d8d1a39 net: create unix sockets in unique directories
This change applies the same transformation as in CL 366774,
but to the net package.

testUnixAddr was using os.CreateTemp to obtain a unique socket path,
but then calling os.Remove on that path immediately. Since the
existence of the file is what guarantees its uniqueness, that could
occasionally result in testUnixAddr returning the same path for two
calls, causing the tests using those paths to fail — especially if
they are the same test or are run in parallel.

Instead, we now create a unique, short temp directory for each call,
and use a path within that directory for the socket address.

For #34611

b55cbbb9e7 net: pass a testing.TB to newLocal* helpers
Passing in an explicit testing.TB gives two benefits:

1. It allows the helper to fail the test itself, instead of returning
   an error to the caller. A non-nil error invariably fails the
   calling test, and none of these callers bother to add detail to the
   error when logging it anyway so returning the error just added
   noise to the test bodies.

2. It allows the helper to use t.Cleanup to perform any needed cleanup
   tasks, which will be used in CL 370695 to clean up temp directories
   used as namespaces for unix socket paths.

For #34611

5e774b0f5c net: simplify deadline fluctuation tests
These tests were checking for fairly narrow timing windows, but were
running in parallel and heavily dependent on timer and goroutine
scheduling. This change eliminates unnecessary goroutines, runs the
tests sequentially (dramatically shortening the timeouts to reduce the
penalty of doing so), and uses timestamp comparison instead of
background timers to hopefully gain some robustness from monotonic
timestamps.

Many of the other tests from this package would benefit from similar
simplifications, which we can apply if and when we notice flaky
failures or want to improve the latency of running the test.

Fixes #36108

f229e7031a all: go fix -fix=buildtag std cmd (except for bootstrap deps, vendor)
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.

08b5091d03 net: close connection in localServer teardown
The transponder sets up a deferred close on accepted connections which
is fine after the client reads all data. However there are no mutexes
nor channels to block the transponder from closing. If the scheduler
runs close before the client read, it will cause an EOF failure.

4f1b0a44cb all: update to use os.ReadFile, os.WriteFile, os.CreateTemp, os.MkdirTemp
As part of #42026, these helpers from io/ioutil were moved to os.
(ioutil.TempFile and TempDir became os.CreateTemp and MkdirTemp.)

Update the Go tree to use the preferred names.

As usual, code compiled with the Go 1.4 bootstrap toolchain
and code vendored from other sources is excluded.

ReadDir changes are in a separate CL, because they are not a
simple search and replace.

For #42026.
