9pfs: performance fix and cleanup

* First patch fixes suboptimal I/O performance on guest due to previously
incorrect block size being transmitted to 9p client.

* Subsequent patches are cleanup ones intended to reduce code complexity.

* remotes/cschoenebeck/tags/pull-9p-20211027:
9pfs: use P9Array in v9fs_walk()
9pfs: make V9fsPath usable via P9Array API
9pfs: make V9fsString usable via P9Array API
fsdev/p9array.h: check scalar type in P9ARRAY_NEW()
9pfs: introduce P9Array
9pfs: simplify blksize_to_iounit()
9pfs: deduplicate iounit code
9pfs: fix wrong I/O block size in Rgetattr

Merge remote-tracking branch 'remotes/gkurz/tags/9p-next-2019-10-10' into staging

The most notable change is that we now detect cross-device setups in the
host since it may cause inode number collision and mayhem in the guest.
A new fsdev property is added for the user to choose the appropriate
policy to handle that: either remap all inode numbers or fail I/Os to
another host device or just print out a warning (default behaviour).

This is also my last PR as _active_ maintainer of 9pfs.

VirtFS update:

Cleanups mostly isolating virtio related details into separate files. This
is done to enable easy addition of Xen transport for VirtFS.

The changes include:

1. Rename a bunch of files and functions to make clear they are generic.
2. disentangle virtio transport code and generic 9pfs code.
3. Some function name clean-up.
