Libnfs 1.8.0 Version Bump, needs help from platform devs.

We need to think about why after nearly a year Linux has no libnfs love, while Windows and everyone else already at version 1.6.1

This is a partial PR to maybe show the improvements that long overdue into making this jump.

I realize more code is required into the compile and makefiles.

Please help with those guys where possible.

Thank you.
