Add macros for linked list operations.
Mostly in preparation to the pending thread-safe list macros. This way,
we have a similar interface to thead-safe and non-thread-safe lists.
This also adds LLIST_FOREACH and LLIST_FIND_FOREACH macros which can be
used as shortcuts when iterating over all list items or a subset of list
items that is accepted by a callback function.
