Log:
Addressing review comments for r261163.

Use "strict" instead of "nopartial". Also make strictly not-introduced
share the same diagnostics as Obsolete and Unavailable.

+version prior to when the declaration was introduced.  When this happens, the
+declaration is `weakly linked
 <https://developer.apple.com/library/mac/#documentation/MacOSX/Conceptual/BPFrameworks/Concepts/WeakLinking.html>`_,
 as if the ``weak_import`` attribute were added to the declaration.  A
 weakly-linked declaration may or may not be present a run-time, and a program
 can determine whether the declaration is present by checking whether the
 address of that declaration is non-NULL.
 
+The flag ``strict`` disallows using API when deploying back to a
+platform version prior to when the declaration was introduced.  An
+attempt to use such API before its introduction causes a hard error.
+Weakly-linking is almost always a better API choice, since it allows
+users to query availability at runtime.

 If there are multiple declarations of the same entity, the availability
 attributes must either match on a per-platform basis or later
 declarations must not have availability attributes for that
