Implement part of Berkeley Socket API for libc-wasi (#1036)
Refer to [Networking API design](https://github.com/WebAssembly/WASI/issues/370) and [feat(socket): berkeley socket API v2](https://github.com/WebAssembly/WASI/pull/459): - Support the socket API of synchronous mode, including `socket/bind/listen/accept/send/recv/close/shutdown`, the asynchronous mode isn't supported yet. - Support adding `--addr-pool=<pool1,pool2,..>` argument for command line to identify the valid ip address range - Add socket-api sample and update the document
