Subject: [PATCH] btrfs-progs: library version defines

commit 46de1a6ec3dbb0db203baa6c46cb64ba9b000ea2 changed the
parameters of btrfs_read_and_process_send_stream().  This breaks
snapper compilation. We can include version defines usable for the C
preprocessor.

Version 0.1.0: API up to and including 46de1a6ec3dbb0db2 (3.14.x)

Version 0.1.1: 909131939f750faffb9fab (changed in 3.16)
