71eb435412 Merged revision(s) 57197, 57206, 57423, 57518 from trunk:
Renamed enable_shared_from_this2 to enable_shared_from_raw and
added shared_from_raw free function.  These changes fix the pointer 
value in shared_ptr which were obtained before an external shared_ptr has
taken ownership of the object (for example when a shared_ptr to
this is obtained in an object's constructor).


........
Brought back code which fixes get_deleter when it is called on a deleter 
which has been wrapped inside a deleter_wrapper by "shared_from_raw() in 
constructors" support.

........
Added weak_from_raw(), for use in conjunction with
enable_shared_from_raw base class.


........
Fixed access to enable_shared_from_raw::weak_this_ when 
BOOST_NO_MEMBER_TEMPLATE_FRIENDS is defined.

28de0cb1e3 Have config/select_stdlib_config.hpp and config/stdlib/stlport.hpp use <cstddef> instead of <utility> to determine which standard library is in use. For std lib implementations that rely on Boost components like TypeTraits, Bind, Function, or SmartPtr, this helps to avoid circular header dependency issues, since <cstddef> is much less likely to pull in Boost libraries than <utility>.
In get_pointer.hpp, switched to using <boost/config/no_tr1/memory.hpp> instead of using <memory> directly.  As above, this helps avoid circular header dependency issues in Boost-supplemented std libs (specifically it avoids issues when <memory> pulls in pieces of Boost.SmartPtr).

These two changes were made in response to testing done with STLport 5.2.1 using the _STLP_USE_BOOST_SUPPORT option.

// typedef <implementation-defined> boost::detail::atomic_count;
//
// atomic_count a(n);
//
// (n is convertible to long)
//
// Effects: Constructs an atomic_count with an initial value of n
//
// a;
//
// Returns: (long) the current value of a
//
// ++a;
//
// Effects: Atomically increments the value of a
// Returns: nothing
//
// --a;
//
// Effects: Atomically decrements the value of a
// Returns: (long) zero if the new value of a is zero,
// unspecified non-zero value otherwise (usually the new value)
//
// Important note: when --a returns zero, it must act as a
// read memory barrier (RMB); i.e. the calling thread must
// have a synchronized view of the memory
//
// On Intel IA-32 (x86) memory is always synchronized, so this
// is not a problem.
//
// On many architectures the atomic instructions already act as
// a memory barrier.
//
// This property is necessary for proper reference counting, since
// a thread can update the contents of a shared object, then
// release its reference, and another thread may immediately
// release the last reference causing object destruction.
//
// The destructor needs to have a synchronized view of the
// object to perform proper cleanup.
//
// Original example by Alexander Terekhov:
//
// Given:
//
// - a mutable shared object OBJ;
// - two threads THREAD1 and THREAD2 each holding
// a private smart_ptr object pointing to that OBJ.
//
// t1: THREAD1 updates OBJ (thread-safe via some synchronization)
// and a few cycles later (after "unlock") destroys smart_ptr;
//
// t2: THREAD2 destroys smart_ptr WITHOUT doing any synchronization
// with respect to shared mutable object OBJ; OBJ destructors
// are called driven by smart_ptr interface...

// atomic_count a(n);
//
// (n is convertible to long)
//
// Effects: Constructs an atomic_count with an initial value of n
//
// a;
//
// Returns: (long) the current value of a
//
// ++a;
//
// Effects: Atomically increments the value of a
// Returns: (long) the new value of a
//
// --a;
//
// Effects: Atomically decrements the value of a
// Returns: (long) the new value of a
//
// Important note: when --a returns zero, it must act as a
// read memory barrier (RMB); i.e. the calling thread must
// have a synchronized view of the memory
//
// On Intel IA-32 (x86) memory is always synchronized, so this
// is not a problem.
//
// On many architectures the atomic instructions already act as
// a memory barrier.
//
// This property is necessary for proper reference counting, since
// a thread can update the contents of a shared object, then
// release its reference, and another thread may immediately
// release the last reference causing object destruction.
//
// The destructor needs to have a synchronized view of the
// object to perform proper cleanup.
//
// Original example by Alexander Terekhov:
//
// Given:
//
// - a mutable shared object OBJ;
// - two threads THREAD1 and THREAD2 each holding
// a private smart_ptr object pointing to that OBJ.
//
// t1: THREAD1 updates OBJ (thread-safe via some synchronization)
// and a few cycles later (after "unlock") destroys smart_ptr;
//
// t2: THREAD2 destroys smart_ptr WITHOUT doing any synchronization
// with respect to shared mutable object OBJ; OBJ destructors
// are called driven by smart_ptr interface...

<h2><a name="Introduction">Introduction</a></h2>
<p>The <STRONG>intrusive_ref_counter</STRONG> class template implements a reference counter for a derived
user&apos;s class that is intended to be used with <STRONG><a href="intrusive_ptr.html">intrusive_ptr</a></STRONG>.
The base class has associated <STRONG>intrusive_ptr_add_ref</STRONG> and <STRONG>intrusive_ptr_release</STRONG> functions
which modify the reference counter as needed and destroy the user's object when the counter drops to zero.</p>
<p>The class template is parameterized on <STRONG>DerivedT</STRONG> and <STRONG>CounterPolicyT</STRONG> parameters.
The first parameter is the user&apos;s class that derives from <STRONG>intrusive_ref_counter</STRONG>. This type
is needed in order to destroy the object correctly when there are no references to it left.</p>
<p>The second parameter is a policy that defines the nature of the reference counter.
Boost.SmartPtr provides two such policies: <STRONG>thread_unsafe_counter</STRONG> and <STRONG>thread_safe_counter</STRONG>. The former
instructs the <STRONG>intrusive_ref_counter</STRONG> base class to use a counter only suitable for a single-threaded use.
Pointers to a single object that uses this kind of reference counter must not be used in different threads. The latter policy
makes the reference counter thread-safe, unless the target platform doesn't support threading. Since in modern systems support for
threading is common, the default counter policy is <STRONG>thread_safe_counter</STRONG>.</p>

<h2><a name="Introduction">Introduction</a></h2>
<p>Consistent use of <a href="shared_ptr.htm"><code>shared_ptr</code></a>
can eliminate the need to use an explicit <code>delete</code>,
but alone it provides no support in avoiding explicit <code>new</code>.
There have been repeated requests from users for a factory function that creates
an object of a given type and returns a <code>shared_ptr</code> to it.
Besides convenience and style, such a function is also exception safe and
considerably faster because it can use a single allocation for both the object
and its corresponding control block, eliminating a significant portion of
<code>shared_ptr</code>'s construction overhead.
This eliminates one of the major efficiency complaints about <code>shared_ptr</code>.
</p>
<p>The header file &lt;boost/make_shared.hpp&gt; provides a family of overloaded function templates,
<code>make_shared</code> and <code>allocate_shared</code>, to address this need.
<code>make_shared</code> uses the global operator <code>new</code> to allocate memory,
whereas <code>allocate_shared</code> uses an user-supplied allocator, allowing finer control.</p>
<p>
The rationale for choosing the name <code>make_shared</code> is that the expression
<code>make_shared&lt;Widget&gt;()</code> can be read aloud and conveys the intended meaning.</p>

<p>The prototypes shown above are used if your compiler supports rvalue references
and variadic templates. They perfectly forward the <code>args</code> parameters to

<p>Otherwise, the implementation will fall back on
forwarding the arguments to the constructors of <code>T</code> as const references.
If you need to pass a non-const reference to a constructor of <code>T</code>,
you may do so by wrapping the parameter in a call to <code>boost::ref</code>.
In addition, you will be
limited to a maximum of 9 arguments (not counting the allocator argument of
allocate_shared).</p>

<h2><a name="Introduction">Introduction</a></h2>
<p>Originally the Boost function templates <code>make_shared</code> and
<code>allocate_shared</code> were for efficient allocation of single
objects only. There was a need to have efficient, single, allocation of
arrays. One criticism of <a href="shared_array.htm">shared_array</a> was
always the lack of a <a href="make_shared.html">make_shared</a> utility
which ensures only a single allocation for an array.</p>
<p>The header files &lt;boost/smart_ptr/make_shared_array.hpp&gt; and
&lt;boost/smart_ptr/allocate_shared_array.hpp&gt; provide new function
templates, <code>make_shared</code> and <code>allocate_shared</code>,
to address this need. <code>make_shared</code> uses the global
operator <code>new</code> to allocate memory, whereas
<code>allocate_shared</code> uses an user-supplied allocator,
allowing finer control.</p>

means that when an exception is thrown by an object of one of these classes,

there are no detectable side effects. Other functions never throw exceptions.
