kerncompat.h header file is part of libbtrfs API. min/max macros cause
conflict while building projects dependant on libbtrfs. Moving those
macros to btrfs-progs internal header file fixes the conflict.

Allow read_tree_block() and read_node_slot() to return error pointer.
This should help caller to get more specified error number.
For existing callers, change (!eb) judgmentt to
(!extent_buffer_uptodate(eb)) to keep the compatibility, and for caller
missing the check, use PTR_ERR(eb) if possible.

This patch pulls back backref.c, adds a couple of helpers everywhere that it
needs, and cleans up backref.c to fit in btrfs-progs. Thanks,
