andrew_programmer 16f5992719 Mistakes in functions of work with files and with system calls KolibriOS are corrected.
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.
