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.

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.

hw/9pfs: Initialize rest of qid field to zero.

Since qid is allocated out of stack we need to intialize
the field to zero. Otherwise we will send wrong qid value
to client.

hw/9pfs: Update the fidp path before opendir

We need to update the fidp path before opendir. Since we don't
use the fid returned by mkdir, earlier code should not have
much issue. We do a double v9fs_string_copy here. The later patch
cleanup the entire function....

we should use the local abstraction instead of
directly calling close.
