Mark Fasheh fac5b559a7 btrfs-progs: Add support for BTRFS_SEND_FLAG_NO_FILE_DATA
The flag and command are synced from kernel to user. Also, this patch adds a
callback for the BTRFS_SEND_C_UPDATE_EXTENT in struct btrfs_send_ops.
read_and_process_cmd() is updated to decode BTRFS_SEND_C_UPDATE_EXTENT and
send the values through the right callback. I did not add a callback
definition to cmds-receive.c as that code never uses
BTRFS_SEND_FLAG_NO_FILE_DATA.
