boot/zfs: Extend zfsimpl.h and make it easier to use
Some makefs(8) patches make use of zfsimpl.h (not zfsimpl.c though) to provide definitions for various on-disk structures. Most of this diff simply adds new definitions that are useful. Also reduce dependencies of the header: - remove an unused list_node_t field to drop the sys/list.h dependency - replace CTASSERT with _Static_assert And fix the declaration of decode_embedded_bp_compressed(). No functional change intended. Reviewed by: tsoome MFC after: 2 weeks Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D35278
