* remote-nindy.c (nindy_open): Acquire more target state so that

Browse Source 
user can attach to a previously running program.
	* (nindy_fetch_registers nindy_store_registers):  Get rid of fp
	conversion code.  That's all handled in {extract store}_floating
	now.
	* utils.c (floatformat_to_double):  Don't bias exponent when
	handling zero's, denorms or NaNs.
	* config/i960/tm-i960.h (REGISTER_CONVERT_TO_VIRTUAL
	REGISTER_CONVERT_TO_RAW):  Change to using DOUBLST and
	FLOATFORMAT_TO/FROM_DOUBLEST macros.
	* config/i960/tm-nindy960.h:  Undefine
	REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW, and
	REGISTER_CONVERTIBLE.  These are no longer necessary now that all
	the magic happens in extract/store_floating.
