/**
* @defgroup Allocators Memory Allocators
* @if maint
* allocator.h implements some node allocators. These are NOT the same as
* allocators in the C++ standard, nor in the original H-P STL. They do not
* encapsulate different pointer types; we assume that there is only one
* pointer type. The C++ standard allocators are intended to allocate
* individual objects, not pools or arenas.
*
* In this file allocators are of two different styles: "standard" and
* "SGI" (quotes included). "Standard" allocators conform to 20.4. "SGI"
* allocators differ in AT LEAST the following ways (add to this list as you
* discover them):
*
* - "Standard" allocate() takes two parameters (n_count,hint=0) but "SGI"
* allocate() takes one paramter (n_size).
* - Likewise, "standard" deallocate()'s argument is a count, but in "SGI"
* is a byte size.
* - max_size(), construct(), and destroy() are missing in "SGI" allocators.
* - reallocate(p,oldsz,newsz) is added in "SGI", and behaves as
* if p=realloc(p,newsz).
*
* "SGI" allocators may be wrapped in __allocator to convert the interface
* into a "standard" one.
* @endif
*
* The canonical description of these classes is in docs/html/ext/howto.html
* or online at http://gcc.gnu.org/onlinedocs/libstdc++/ext/howto.html#3

* @if maint
* Another allocator adaptor: _Alloc_traits. This serves two purposes.
* First, make it possible to write containers that can use either "SGI"
* style allocators or "standard" allocators. Second, provide a mechanism
* so that containers can query whether or not the allocator has distinct
* instances. If not, the container can avoid wasting a word of memory to
* store an empty object. For examples of use, see stl_vector.h, etc, or
* any of the other classes derived from this one.
*
* This adaptor uses partial specialization. The general case of
* _Alloc_traits<_Tp, _Alloc> assumes that _Alloc is a
* standard-conforming allocator, possibly with non-equal instances and
* non-static members. (It still behaves correctly even if _Alloc has
* static member and if all instances are equal. Refinements affect
* performance, not correctness.)
*
* There are always two members: allocator_type, which is a standard-
* conforming allocator type for allocating objects of type _Tp, and
* _S_instanceless, a static const member of type bool. If
* _S_instanceless is true, this means that there is no difference
* between any two instances of type allocator_type. Furthermore, if
* _S_instanceless is true, then _Alloc_traits has one additional
* member: _Alloc_type. This type encapsulates allocation and
* deallocation of objects of type _Tp through a static interface; it
* has two member functions, whose signatures are
*
* - static _Tp* allocate(size_t)
* - static void deallocate(_Tp*, size_t)
*
* The size_t parameters are "standard" style (see top of
* allocator.h) in that they take counts, not sizes.
