Solaris supports accept4 since version 11.4, see
https://docs.oracle.com/cd/E88353_01/html/E37843/accept4-3c.html
Use it in internal/poll.accept like on other platforms.

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.

Illumos supports the accept4 syscall, use it in internal/poll.accept
like on other platforms.
Add Accept4 to package syscall despite the package being frozen. The
other option would have been to add this to internal/syscall/unix, but
adding it to syscall avoids duplicating a lot of code in internal/poll
and net/internal/socktest. Also, all other platforms supporting the
accept4 syscall already export Accept4.

This will make it possible to use the poller with the os package.
This is a lot of code movement but the behavior is intended to be
unchanged.

This change adds socket system call hooks to existing test cases for
simulating a bit complicated network conditions to help making timeout
and dual IP stack test cases work more properly in followup changes.
Also test cases print debugging information in non-short mode like the
following:
