As opposed to standard modules, LuaSocket is an hybrid Lua/C package.
As the name implies, the luaopen_socket_core functions implements the
socket.core module, not socket. The socket module is implemented in
Lua (in socket.lua).

So you need to make sure luaopen_socket_core is loaded as
"socket.core" (that is the value of LUA_SOCKETLIBNAME), and you need
to embed the socket.lua file and load it somehow.
