#10897: Pool allocator does not perfect forward it's argument

Milestone:  To Be Determined   |  Component:  pool
  Version:  Boost 1.58.0       |   Severity:  Problem

-------------------------------+----------------------
 The pool_allocator library has not been updated to C++11 yet.
 One of the greatest missing feature is the lack of perfect forwarding of
 the parameters of "conctruct" in pool_allocator and fast_pool_allocator.
 This prevent the move constructor of the allocated object to be called.
 Right now the construct implementation is as follow:

 {{{
 static void construct(const pointer ptr, const value_type & t)
 { new (ptr) T(t); }
 }}}

 while it should be:
 {{{
 template<typename ...Args>
 static void construct(const pointer ptr, Args&& ...args)
 { new (ptr) T(std::forward<Args> (args)...); }
 }}}
