Andrey Semashev c22d7f5bda Added value() accessor to atomic template, deprecated storage(). ...

This commit changes how storage alignment is enforced and ensures
that the storage is sufficiently aligned for both atomic operations
and direct access to the stored value. This allowed to implement
the new value() accessor, which returns a reference to the stored
value. This is unlike the previously available storage() accessor,
which returns a reference to storage_type and requires users to cast
the reference to value_type, which is potentially unsafe.

The public storage() accessor is now deprecated in favor of value()
and storage_type - in favor of value_type. The deprecation warnings
can be disabled by defining BOOST_ATOMIC_SILENCE_STORAGE_DEPRECATION.
