Deprecate SA_xxx interrupt flags -V2

Browse source 
The deprecation of the SA_xxx interrupt flags did not emit deprecated
warnings. Andrew said about the removal of the deprecated flag defines:

> This is going to break a lot of external stuff.  We should have found
> a way to make usage of SA_* emit deprecated warnings (or _some_
> warning) to warn people of impending doom.  But I can't immediately

Define the deprecated flags as a call to a __deprecated inline function
so a warning is emitted on compile time.

Extend the reprieve of out of tree drivers to 9/2007.
