Add support for user/password authentication

[rmohr]

Hi,

@rgbkrk great project.

I added basic user/password authentication to libvirt-go. The PR is not finished yet but it already works.

It would be gread if I could get some feedback.

Would you be able to write a test for this?

Thanks for the contribution, seems to be aligned pretty well.

Rewrote it to comply with cgo 1.6 pointer rules. Thanks for the initial review.

I will add a test too.

I think you could wrap everything in C code. This way, you just have to invoke the C function from Go code and not handle all the callback and allocation stuff in Go code.

I'll try it, but I don't think it would save me more than one or two C.free calls. Let's see..
