This patch use file system specific ioctl for getting i_generation
value. Not all file system support the ioctl. So we add an export
specific extended operation and assign right callback for the
file system that support i_generation ioctl
["M. Mohan Kumar" <mohan@in.ibm.com> we can do ioctl only for
regular files and directories on the server]

If the 9pfs mount tag is longer than MAX_TAG_LEN bytes, rather than
silently truncating the tag which will likely break the guest OS,
report an immediate error and exit QEMU
* hw/9pfs/virtio-9p-device.c: Report error & exit if mount tag is
too long

Commit 353ac78d49 moved the files
without fixing the include paths. It used a modified CFLAGS
to add hw to the include search path, but this breaks builds
where the user wants to set special CFLAGS. Long include paths
also increase compilation time.
Therefore this patch removes the special CFLAGS for virtio
and fixes the include statements by using relative include paths.
v2: Remove special CFLAGS.
v3: Update needed for latest QEMU.
