[PATCH] 9p: fix name consistency problems

There were a number of conflicting naming schemes used in the v9fs project.
The directory was fs/9p, but MAINTAINERS and Documentation referred to
v9fs.  The module name itself was 9p2000, and the file system type was 9P.
This patch attempts to clean that up, changing all references to 9p in
order to match the directory name.  We'll also start using 9p instead of
v9fs as our patch prefix.

There is also a minor consistency cleanup in the options changing the name
option to uname in order to more closely match the Plan 9 options.
