Richi has asked the we break the wide-int patch so that the individual port and front end maintainers can review their parts without have to go through the entire patch.    This patch covers the decimal floating point code.

Ok?
* dfp.c: Include wide-int.h.
	(decimal_real_to_integer2): Use wide-int interfaces and rename to
	decimal_real_to_integer.
	* dfp.h
	(decimal_real_to_integer2): Return a wide_int and rename to
	decimal_real_to_integer.
