* stub out more types/funcs to compile against golang.org/x/net/internal/socket
These are changes need to compile github.com/domainr/dnsr/ with TinyGo.
See issue https://github.com/tinygo-org/net/issues/14.
These change are mostly to fix missing symbols in src/crypto/tls and
src/net. Missing types and functions are cut-and-pasted from go1.21.4.
Functions are stubbed out returning errors.New("not implemented").
DNRS is compiled by running tinygo test:
sfeldma@nuc:~/work/dnsr$ tinygo test -target=wasi
With this patch, and a corresponding patch for tinygo-org/net to fixup
src/net, you should get a clean compile.
This mostly works around the default CGo support: this compiler doesn't
need special wrappers for C functions as it uses the C calling
convention by default.
