The send.h is exported for libbtrfs and includes ctree.h but it lacks
the in-tree/out-of-tree ifdef switch. This would be a problem once
ctree.h moves.

Large numbers like (1024 * 1024 * 1024) may cost reader/reviewer to
waste one second to convert to 1G.
Introduce kernel include/linux/sizes.h to replace any intermediate
number larger than 4096 (not including 4096) to SZ_*.

Please find attached a patch to make the new libbtrfs usable from
C++ (at least for the parts snapper will likely need).

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.
