#9949: clear header node hooks upon intrusive container destruction
------------------------------------+------------------------
 Reporter:  Matei David <matei@…>   |      Owner:  igaztanaga
     Type:  Feature Requests        |     Status:  new
Milestone:  To Be Determined        |  Component:  intrusive
  Version:  Boost 1.55.0            |   Severity:  Problem
 Keywords:  intrusive header hooks  |
------------------------------------+------------------------
 In intrusive containers, the `safe_link` and `auto_unlink` hook types
 cause boost to reset the hooks to their default constructed state (usually
 `NULL`) upon removing an element from a container. That suggests a user
 could double check that nodes are indeed removed from all containers upon
 destruction, by checking that the hooks are set to `NULL`. Unfortunately,
 the check fails because, unlike all other regular nodes, the hooks of the
 container //header// nodes are not reset upon destruction of the
 container.

 I will create a pull request which rectifies this in `list`, `slist`, and
 `bstree`. I will drop it on top of the develop branch, which has the
 recent fix to bug #9940.

 I believe the change should have no negative impact.
