	* win/makefile.vc: Rewrite of Tcl_PrintDouble and TclDoubleDigits
	that (a) fixes a severe performance problem with floating point
	shimmering reported by Karl Lehenbauer, (b) allows TclDoubleDigits
	to generate the digit strings for 'e' and 'f' format, so that it
	can be used for tcl_precision != 0 (and possibly later for [format]),
	(c) fixes [Bug 3120139] by making TclPrintDouble inherently
	locale-independent, (d) adds test cases to util.test for
	correct rounding in difficult cases of TclDoubleDigits where fixed-
	precision results are requested. (e) adds test cases to util.test for
	the controversial aspects of [Bug 3105247]. As a side effect, two
	more modules from libtommath (bn_mp_set_int.c and bn_mp_init_set_int.c)
	are brought into the build, since the new code uses them.
