ufs: added mostly working unix filesystem server session implementation

[progrium]

This adds a real implementation of 9ps that doesn't depend on another project. This implementation was loosely based on the go9p project ufs implementation. It's not entirely complete, but enough to use 9pr directly with 9ps with a real filesystem.

I was able to get this working with the Linux kernel 9p client with the commits from #39 and progrium/go-p9p#1.

Please sign your commits following these rules: https://github.com/moby/moby/blob/master/CONTRIBUTING.md#sign-your-work The easiest way to do this is to amend the last commit:

$ git clone -b "ufs" git@github.com:progrium/go-p9p.git somewhere
$ cd somewhere
$ git rebase -i HEAD~842353879960
editor opens
change each 'pick' to 'edit'
save the file and quit
$ git commit --amend -s --no-edit
$ git rebase --continue # and repeat the amend for each commit
$ git push -f

Amending updates the existing PR. You DO NOT need to open a new one.

I believe all commits have DCO now.

[progrium]

Rebased with #39 since it's required for a working, mountable implementation. Also happened to rebase with #40 because it just makes sense. If for some reason these aren't desirable I can recreate this PR, but I figured these all make sense together.
