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.
