Subject: [PATCH] btrfs-progs: move uuid-tree definitions to
 kernel-shared/uuid-tree.h

Currently we already have a kernel-shared/uuid-tree.c, which is mostly
shared with kernel.

Kernel also has a uuid-tree.h, but we are still using ctree.h for the
header.

Move all the uuid-tree related definitions to kernel-shared/uuid-tree.h,
making future code sync easier.
