Allow Setting Socket Type on Creation

[ckreiling]

Currently the default Unix Socket Type is set to SOCKET_STREAM. I have a use case for SOCKET_SEQPACKET, but unfortunately have to edit the source code myself in order to achieve this.

Is there perhaps a chance that the static connect functions could be overloaded for the socket type to be passed as an option?

Perhaps you could put together a PR like this one?

#46

Someone else also wanted to expose the socket API in #45 (fixing #44) but since this isn't a general-purpose BSD socket library I'd prefer to do that as a separate jnr project (jnr-socket, for example). This project would then depend on that one.

If you would like to help on either of these items, let me know!
