This series covers support for following btrfs ioctls

    *BTRFS_IOC_DEFAULT_SUBVOL        *BTRFS_IOC_QUOTA_RESCAN
    *BTRFS_IOC_GET_SUBVOL_ROOTREF    *BTRFS_IOC_QUOTA_RESCAN_WAIT
    *BTRFS_IOC_QUOTA_CTL             *BTRFS_IOC_SCRUB
    *BTRFS_IOC_QGROUP_CREATE         *BTRFS_IOC_SCRUB_CANCEL
    *BTRFS_IOC_QGROUP_ASSIGN         *BTRFS_IOC_SCRUB_PROGRESS
    *BTRFS_IOC_INO_PATHS             *BTRFS_IOC_QGROUP_LIMIT
    *BTRFS_IOC_LOGICAL_INO           *BTRFS_IOC_QUOTA_RESCAN_STATUS
    *BTRFS_IOC_LOGICAL_INO_V2
    *BTRFS_IOC_INO_LOOKUP_USER
    *BTRFS_IOC_INO_LOOKUP

The functionalities of individual ioctls were described in this series
patch commit messages. Since all of these ioctls are added in kernel
version 3.9, their definitions in file 'linux-user/ioctls.h' are
enwrapped in an #ifdef directive.

Testing method:

    Mini test programs were written for these ioctls. These test programs
    can be found on a repository which is located on the link:
    https://github.com/bozutaf/btrfs-tests

    These test programs were compiled (sometimes using cross compilers) for
    following architectures:

         * Intel 64-bit (little endian)
         * Power pc 32-bit (big endian)
         * Power pc 64-bit (big endian)

    The corresponding native programs were executed without using QEMU on
    an intel x86_64 host.

    All applicable compiled programs were in turn executed through QEMU
    and the results obtained were the same ones gotten for native
    execution.
