    lib: errno: introduce errno_str(): returns errno related message · 59345b1f
    Przemyslaw Marczak authored
    The functions error's numbers are standarized - but the error
    messages are not.
    
    The errors are often handled with unclear error messages,
    so why not use an errno standarized messages.
    
    Advantages:
    - This could decrease the binary size.
    - Appended with a detailed information,
      the error message will be clear.
    
    This commit introduces new function:
    - const char *errno_to_str(int errno)
    
    The functions returns a pointer to the errno corresponding text message:
    - if errno is null or positive number - a pointer to "Success" message
    - if errno is negative - a pointer to errno related message
