2289be19ae hw/9pfs: Move fid pathname tracking to seperate data type. 
This enables us to add handles to track fids later. The
V9fsPath added is similar to V9fsString except that the
size include the NULL byte also.

02cb7f3a25 hw/9pfs: Use read-write lock for protecting fid path. 
On rename we take the write lock and this ensure path
doesn't change as we operate on them.

ff06030f66 [virtio-9p] Change all pdu handlers to coroutines. 
This patch changes the top level handlers to coroutines and sets the base.
It will be followed up with series of patches to convert all filesystem
calls to threaded coroutines pushing all blocking clals in VirtFS out
of vcpu threads.
