Message:

Improve lists and other data structures

Provide more standard-compliant member_to_inst implementation that uses
offsetof. Avoid potential undefined behavior in list_foreach and
list_foreach_rev by avoiding assinging an unaligned pointer value. Use
size_t instead of unsigned long for list length.
