New functions for work with system calls KolibriOS are added. Functions for format output are added: printf (), fprintf (), sprintf (), snprintf (), vsnprintf (). For material numbers it is meanwhile supported only format output the (%f), and exponential output a (%e) is not realized yet. Functions for format output correctly work only in GCC because TinyC incorrectly works with the functions containing variable number of arguments. git-svn-id: svn://kolibrios.org@647 a494cfbc-eb01-0410-851d-a64ba20cac60
