Three basic userspace components to improve v9fs usability under Linux.

MOUNT HELPER

* hueristic for determining transport type
* DNS support for resolving hostname <->ip address
* ssh-based tunneling support (will require server work as well)
* man pages
* debian packaging
* rpm packaging
* (stretch) authentication support (w/p9p)
* (stretch) integration with idmap solution

SERVER

* based on spfs/npfs
* allow for multiple exports w/anames and specification of root directory
* man pages
* debian packaging
* rpm packaging
* (stretch) authentication support (w/p9p)
* (stretch) integration with idmap solution

IDMAP

* maps local uids/gids/error-codes to strings
* userspace daemon to provide mapping
* hooks in v9fs to use mapping
* (stretch) synthetic file server approach to update mappings
