btrfs-progs: libbtrfs: remove max/min macros from API
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. Signed-off-by: Ondrej Kozina <okozina@redhat.com> Signed-off-by: David Sterba <dsterba@suse.com>
