b079640404 misc/cgo/test: simplify for module mode
When we were first introducing module mode, CL 163418 moved many of
the tests in misc/cgo/test into their own test binary under testdata
so misc/cgo/test continued to work in both GOPATH mode and module
mode. This introduce a somewhat complicated test driver into
misc/cgo/test. Since the misc/cgo/test test had to invoke "go test" as
a subprocess, this required care to thread any build flags down into
the subprocess. The output from any failures of the sub-process was
also less than ideal.

Now that we don't have to worry about running these in GOPATH mode any
more, this CL moves all of the tests back into misc/cgo/test and drops
the test driver.

There are two slight complications:

- Test41761 was added after this split and has a C type "S" that's
  also present in misc/cgo/test itself. We rename that to keep that
  test working.

- TestCgo in go/internal/srcimporter now fails to import misc/cgo/test
  because misc/cgo/test now contains imports of other "misc" module
  packages and the importer it sets up isn't configured to allow that.
  We fix this by setting up a build context that's configured for
  this.

Preparation for #37486.

551af5f50a misc/cgo/test: fix tests in module mode
This change preserves the ability to test misc/cgo/test in GOPATH
mode, at the cost of indirection through a 'go test' subprocess.

Updates #30228

200e7bf6b1 misc/cgo: fix issue 9400 test on 386
issue9400_linux.go did not build on 386 because it used a constant
that was larger than a 32-bit int in a ... argument.  Fix this by
casting the constant to uint64 (to match how the constant is being
used).

675eb72c28 runtime: run libc SIGSETXID and SIGCANCEL handlers on signal stack
These signals are used by glibc to broadcast setuid/setgid to all
threads and to send pthread cancellations.  Unlike other signals, the
Go runtime does not intercept these because they must invoke the libc
handlers (see issues #3871 and #6997).  However, because 1) these
signals may be issued asynchronously by a thread running C code to
another thread running Go code and 2) glibc does not set SA_ONSTACK
for its handlers, glibc's signal handler may be run on a Go stack.
Signal frames range from 1.5K on amd64 to many kilobytes on ppc64, so
this may overflow the Go stack and corrupt heap (or other stack) data.

Fix this by ensuring that these signal handlers have the SA_ONSTACK
flag (but not otherwise taking over the handler).

This has been a problem since Go 1.1, but it's likely that people
haven't encountered it because it only affects setuid/setgid and
pthread_cancel.

Fixes #9600.
