Rename rawsockets module to nativesockets

This change was done to avoid confusion with TCP/IP raw sockets. Native sockets
module represents handling native system low level socket API in general and is
not just limited anyhow to TCP/IP raw sockets.

A stub lib/deprecated/pure/rawsockets.nim module has been added as
compatibility layer for old code using rawsockets, so this change will not
break existing code.
