hw/9pfs: Improve portability to older systems

handle fs driver require a set of newly added syscalls. Don't
Compile handle FS driver if those syscalls are not available.
Instead of adding #ifdef for all those syscalls we check for
open by handle syscall. If that is available then rest of the...

all.

9pfs: improve portability to older systems

Small requirements on "new" features have percolated to virtio-9p-local.c.
In particular, the utimensat wrapper actually only supports dirfd = AT_FDCWD
and flags = AT_SYMLINK_NOFOLLOW in the fallback code. Remove the arguments...

9p: pass dotl flags to the unlinkat method

AT_REMOVEDIR is not defined on all systems. Pass the raw flags from the
9p protocol, which are always there.

configure: fix detection for xattr.h on modern distributions

Modern distributions place xattr.h in /usr/include/sys, and fold
libattr.so into libc. They also don't have an ENOATTR.

Make configure detect this, and add a qemu-xattr.h file that
directs the #include to the right place....

hw/9pfs: use g_vasprintf() instead of rolling our own

Markus Armbruster <> sent fixes for va_list vararg
issues in v9fs_string_alloc_printf(). It turns out the function
duplicates g_vasprintf() and can therefore be eliminated entirely.

hw/9pfs: Add synthetic file system support using 9p

This patch create a synthetic file system with mount tag
v_synth when -virtfs_synth command line option is specified
in qemu. The synthetic file system can be mounted in guest
using 9p using the below command line...

hw/9pfs: Replace rwlocks with RCU variants of interfaces.

Use QLIST_INSERT_HEAD_RCU and rcu_read_lock/unlock instead of rwlocks.
Use v9fs_synth_mutex as a write-only mutex to handle concurrent writers.

hw/9pfs: Abstract open state of fid to V9fsFidOpenState

To implement synthetic file system in Qemu we may not really
require file descriptor and Dir *. Make generic code use
V9fsFidOpenState instead.
