Deprecate SA_xxx interrupt flags -V2
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.

What: Interrupt only SA_* flags
-When: Januar 2007
+When: September 2007
Why: The interrupt related SA_* flags are replaced by IRQF_* to move them
out of the signal namespace.
