Wasmtime 14.0.0 introduced new CLI flags and removed the existing
flags, in particular the --max-wasm-stack flag we were using to avoid
errors in some tests.
This introduces a regular expression based switch that uses the old
flags for wasmtime versions < 14 and the new flags otherwise.
Fixes#63718

The latest version of Wasmtime, 14.0.4 as of writing this, offers a new
CLI while also supporting the old CLI. Since this is known and tracked
in issue #63718, silence the warning that otherwise causes many tests
to fail.
Since Wasmtime 13 and older don't pay attention to WASMTIME_NEW_CLI,
this change increases compatibility of the script, letting it work
with Wasmtime 9.0.1 as currently tested by the old cmd/coordinator, and
with Wasmtime 14.0.4 as currently tested in the new LUCI infrastructure.
The rest of the transition is left as future work.
For #63718.
For #61116.

The default WASI runtime was originally set to Wazero, because it was
the first runtime used to test the Go implementation and because we
could easily find and fix issues in our implementation and theirs.
In CL 498675 we switched the default wasip1 runner to Wasmtime as it
runs faster and is a more established and mature runtime. We should
switch the default runtime to Wasmtime to consistently promote
Wasmtime as the primary tested and approved runtime.

Implements net.FileListener and net.FileConn for wasip1.
net.FileListener can be used with a pre-opened socket. If the WASM
module knows the file descriptor, a listener can be constructed with:
l, err := net.FileListener(os.NewFile(fd, ""))
If the WASM module does not know the file descriptor, but knows that at
least one of the preopens is a socket, it can find the file descriptor
and construct a listener like so:
func findListener() (net.Listener, error) {
// We start looking for pre-opened sockets at fd=3 because 0, 1,
// and 2 are reserved for stdio. Pre-opened directories also
// start at fd=3, so we skip fds that aren't sockets. Once we
// reach EBADF we know there are no more pre-opens.
for preopenFd := uintptr(3); ; preopenFd++ {
l, err := net.FileListener(os.NewFile(preopenFd, ""))
var se syscall.Errno
switch errors.As(err, &se); se {
case syscall.ENOTSOCK:
continue
case syscall.EBADF:
err = nil
}
return l, err
}
}
A similar strategy can be used with net.FileConn and pre-opened
connection sockets.
The wasmtime runtime supports pre-opening listener sockets:
