abv 91322f44fd 0022898: IGES import fails in german environment 
Added DRAW command dlocale to set and query current locale of the C subsystem
Equivalents of C functions working with conversions of strings to/from reals added in Standard_CString, providing locale-independent behavior (using always "C" locale)
In DRAW packages, calls to atof() and atoi() are replaced by direct calls to Draw::Atof() and Draw::Atoi(), respectively, instead of substituting by #define
Use of atof(), strtod(), and *scanf() involving floating point conversions in OCCT code replaced by locale-independent Atof() and Strtod()
Calls to sprintf() involving floating point in OCCT code are replaced by call to locale-independent Sprintf(), except a few places where converted strings are used immediately for display in the 3d viewer
Changes of global locale are eliminated throughout OCCT code
Proposed correction for GNU libC where v*printf_l functions are absent
Added test case (bugs xde bug22898) for data exchange operations with non-standard locale
Use xlocale on Mac OS X and within glibc
Corrected strtod_l wrapper
Generate error rather than warning
Introduce Standard_CLocaleSentry replacement for removed OSD_Localizer
Standard_CLocaleSentry - copy locale string
Standard_CLocaleSentry - use _configthreadlocale on Windows
Standard_CLocaleSentry::GetCLocale() - return locale_t rather than void*
Corrected misprint in ~Standard_CLocaleSentry()
Use French locale in bug22898 test case
Mark test case as skipped if locale is unavailable on tested system.
Use fr_FR locale for tests on Mac OS X
