-Subject: [PATCH 12/16] Use local bsdqueue.h
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Not all systems provide a sys/queue.h implementation. For example the the musl
-C library does not and will not have it [1].
-
-sys/queue.h first appeared in 4.4BSD and is used in all 4.4BSD variants. Note
-that glibc' sys/queue.h is a patched version of this 4.4BDS header (adds
-STAILQ_CONCAT and TAILQ_CONCAT).
-
-There exists several implementations of sys/queue.h. Lets use the version from
-the NetBSD project [2] and provide it as a local header file "bsdqueue.h"
-

-+ * This file defines five types of data structures: singly-linked lists,
-+ * lists, simple queues, tail queues, and circular queues.
-+ *
-+ * A singly-linked list is headed by a single forward pointer. The
-+ * elements are singly linked for minimum space and pointer manipulation
-+ * overhead at the expense of O(n) removal for arbitrary elements. New
-+ * elements can be added to the list after an existing element or at the
-+ * head of the list. Elements being removed from the head of the list
-+ * should use the explicit macro for this purpose for optimum
-+ * efficiency. A singly-linked list may only be traversed in the forward
-+ * direction. Singly-linked lists are ideal for applications with large
-+ * datasets and few or no removals or for implementing a LIFO queue.
-+ *
-+ * A list is headed by a single forward pointer (or an array of forward
-+ * pointers for a hash table header). The elements are doubly linked
-+ * so that an arbitrary element can be removed without a need to
-+ * traverse the list. New elements can be added to the list before
-+ * or after an existing element or at the head of the list. A list
-+ * may only be traversed in the forward direction.
-+ *
-+ * A simple queue is headed by a pair of pointers, one the head of the
-+ * list and the other to the tail of the list. The elements are singly
-+ * linked to save space, so elements can only be removed from the
-+ * head of the list. New elements can be added to the list after
-+ * an existing element, at the head of the list, or at the end of the
-+ * list. A simple queue may only be traversed in the forward direction.
-+ *
-+ * A tail queue is headed by a pair of pointers, one to the head of the
-+ * list and the other to the tail of the list. The elements are doubly
-+ * linked so that an arbitrary element can be removed without a need to
-+ * traverse the list. New elements can be added to the list before or
-+ * after an existing element, at the head of the list, or at the end of
-+ * the list. A tail queue may be traversed in either direction.
-+ *
-+ * A circle queue is headed by a pair of pointers, one to the head of the
-+ * list and the other to the tail of the list. The elements are doubly
-+ * linked so that an arbitrary element can be removed without a need to
-+ * traverse the list. New elements can be added to the list before or after
-+ * an existing element, at the head of the list, or at the end of the list.
-+ * A circle queue may be traversed in either direction, but has a more
-+ * complex end of list detection.
-+ *
-+ * For details on the use of these macros, see the queue(3) manual page.
-+ */
-+
-+/*
-+ * Include the definition of NULL only on NetBSD because sys/null.h
-+ * is not available elsewhere. This conditional makes the header
-+ * portable and it can simply be dropped verbatim into any system.
-+ * The caveat is that on other systems some other header
-+ * must provide NULL before the macros can be used.
