printf-hooks-2009-02-27.patch

This is getting closer to the design that Ulrich requested.

There's still a 'free()' callback but this will be replaced by a sizeof(type)
requirement on the registration function and the storage will be managed
internally by glibc.

Also, I currently have two separate registration functions because the length
modifier doesn't need all of the callbacks that the conversion specifier needs.
 These can certainly be unified if necessary.

Finally, I haven't implemented flag overrides because I'm not sure it is
necessary at this point.  (None of the draft specs include flag overrides).
