Disable NFS

I am not feel slowness from vboxsf over nfs, but I am bored by permanent
rewriting of my /etc/exports.
Rewrite logger initialization
Use master_port from server, if local one not specified
Revert NFS back, setup.py sdist not works over vboxfs

(Partially revert c9835113b844a2d9f4321cd8e77f09b9991068c2)
