* generic/tclInt.decls: * generic/tclInt.h: * generic/tclStrToD.c: * generic/tclTest.c: * generic/tclTomMath.decls: * generic/tclUtil.c: * tests/util.test: * unix/Makefile.in: * win/Makefile.in: * 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.
