[PATCH 00/20] tests/9p: introduce declarative function calls

[Christian Schoenebeck <qemu_oss@crudebyte.com>]

This series converts relevant 9p (test) client functions to use named
function arguments. For instance

    do_walk_expect_error(v9p, "non-existent", ENOENT);

becomes

    twalk({
        .client = v9p, .path = "non-existent", .expectErr = ENOENT
    });

The intention is to make the actual 9p test code more readable, and easier
to maintain on the long-term.

Not only makes it clear what a literal passed to a function is supposed to
do, it also makes the order and selection of arguments very liberal, and
allows to merge multiple, similar functions into one single function.

This is basically just refactoring, it does not change behaviour.
