Commit c47b976df339ea896b2ba5cf535b9bc07c13534c in qpid-dispatch's branch

DISPATCH-1299 - Added safe-reference feature to the alloc-pool module.
Note: alloc-malloc also has the same interface (will build), but does not
provide the same safety.
> Provide API access to the already existing safe-reference capability in
> alloc-pool

> Key: DISPATCH-1299
> URL: https://issues.apache.org/jira/browse/DISPATCH-1299
> Project: Qpid Dispatch
> Issue Type: Improvement
> Components: Container
> Reporter: Ted Ross
> Assignee: Ted Ross
> Priority: Major
> Fix For: 1.6.0
>
>
> This improvement adds the following two functions to the list of functions
> generated per pooled type:
> {{typedef ... <typename>_sp;}}
> {{void set_safe_ptr(<typename> *p, <typename>_sp *sp);}}
> {{<typename> *safe_deref_<typename>(<typename>_sp sp);}}
> A user of this feature can declare or allocate a safe-pointer, set the
> safe-pointer using a normal object pointer, and dereference the safe-pointer
> later to yield the original normal pointer. If, in the interim time, the
> object was freed, the safe-dereference will yield a NULL pointer rather than
> a stale (possibly re-used) pointer.
