poll only returns active events in revents table, increases performance
Moved getaddrinfo() out of socket functions. getaddrinfo() is now exposed and returns a table with resolving results. connect(), bind() and sendto() now accept a table with family, port and addr fields
Merge branch 'master' of https://github.com/luaposix/luaposix into socket
Cleaned up all other references to getaddrinfo
