btrfs-progs: libify some parts of btrfs-progs
External software wanting to use the functionality provided by the btrfs send ioctl has a hard time doing so without replicating tons of work. Of particular interest are functions like btrfs_read_and_process_send_stream() and subvol_uuid_search(). As that functionality requires a bit more than just send-stream.c and send-utils.c we have to pull in some other parts of the progs package. This patch adds code to the Makefile and headers to create a library, libbtrfs which the btrfs command now links to. Signed-off-by: Mark Fasheh <> Signed-off-by: David Sterba <>
