TCollection_ExtendedString/TCollection_AsciiString description has been updated to reflect usage of this classes for Unicode strings. TCollection_ExtendedString now defines constructor taking wchar_t* (all platforms) and method ::ToWideString() returning wchar_t* (Windows only). TCollection_AsciiString now defines constructor taking wchar_t*. TCollection_ExtendedString/TCollection_AsciiString now defines auxiliary methods ::StartsWith() and ::EndsWith(). TCollection_ExtendedString internals has been updated to eliminate duplicated code for converting between UTF-16 and UTF-8. Code has been cleaned up from redundant explicit conversions to wchar_t*. Global method OSD_OpenStream()/OSD_OpenFileBuf() have been replaced by C++ template to eliminate copy-paste for different STL collections. OSD_SharedLibrary now uses wide-char system API call LoadLibraryExW() on Windows for consistency. New macro Standard_UNUSED has been added for marking possibly unused functions and variables (to suppress gcc/clang compiler warnings).
