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
