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.

It has been observed that setgid hangs when using cgo with musl.
This fix ensures that signal 34 gets handled in an appropriate way,
like signal 33 when using glibc.
Fixes #39343

CL 49590 made it possible for external signal handlers to catch
signals from a crashing Go process. This CL extends that support
to handlers registered after the Go runtime has initialized.
Updates #20392 (and possibly fix it).

The _SigUnblock flag was appended to SIGSYS slot of runtime signal table
for Linux in https://go-review.googlesource.com/22202, but there is
still no concrete opinion on whether SIGSYS must be an unblocked signal
for runtime.
This change removes _SigUnblock flag from SIGSYS on Linux for
consistency in runtime signal handling and adds a reference to #15204 to
runtime signal table for FreeBSD.
Updates #15204.

On GNU/Linux, SIGSYS is specified to cause the process to terminate
without a core dump. In https://codereview.appspot.com/3749041 , it
appears that Golang accidentally introduced incorrect behavior for
this signal, which caused Golang processes to keep running after
receiving SIGSYS. This change reverts it to the old/correct behavior.
Updates #15204

Use the current ability to say that we don't do anything with SIGCONT by
default, but programs can catch it using signal.Notify if they want.
Fixes #8953.

Linux/mips64 uses a different signal table. To avoid code copying,
signal table is factored out from signal_linux.go to
sigtab_linux_generic.go. And a mips64-specific version is added.
