remove walk-ok in favour of expect(Rwalk)

comment out the 9P2000.L stuff Initially I thought to support the .L dialect, but now I'm not that sure. Tread on a directory is not that hard, and I personally like that more than the .L alternative of the Treaddir, it's ugly. Some .L stuff may be interesting to support, at least for symlinks, but at least for a first version I want to keep it simple and implement plain 9P2000.

add a failing test spotted by cage, thanks!

ensure that a walk with zero paths don't replies with a qid A walk of zero paths is used to duplicate a fid. it doesn't make sense to reply with a body containing the qid relative to the file, because it's not a real walk, it's just a duplication. Furthermore, it would break the expectations that the number of qid returned is less or equal to the walked components.

group the "no body replies" handling together

Tcreate: specify that . and .. are illegal

improve README.md

dump REGRESS_* vars to stdout

document other calls

Tcreate: check against ".", ".." and files with `/' in them.

add Tcreate, Twrite and Tremove

Merge branch 'main' of ssh://omarpolo.com/kamid

- [regress-extra] added test for tCreate, both file and directory.

implement Tremove
