[PATCH 4/4 v2] Btrfs-progs: add write and clone commands debug info to receive

[Filipe David Borba Manana <fdmanana@gmail.com>]

When specifying -vv print information about received write and clone commands too,
as we do this for other commands already and it's very useful for debugging and
troubleshooting.

V2: Added new send ioctl flag BTRFS_SEND_FLAG_SUPPORT_FALLOCATE. A version 2
    stream is now only produced is the ioctl caller specifies at least one of
    the new send flags (BTRFS_SEND_FLAG_SUPPORT_FALLOCATE or
    BTRFS_SEND_FLAG_CALCULATE_DATA_SIZE).
