stat: fix `mode' format
Select only the lower two and set the correct bit for directory entries. While the lower two bytes seems to behave just as on UNIX, the upper ones don't (at least on OpenBSD.)
Tattach: handle aname ""
9front uses aname "" during Tattach, at least with 9fs without special arguments, so convert it to our current representation.
fix format of Rstat
`count' should be a 2-byte (16-bit) value and we're not neither accounting for it nor sending it.
