eb5b63f369 lib: errno: sync error codes
Macro ERRNO_MSG() ignores the error number but we should still use the same
constants as in include/linux/errno.h.

If errno_str() is called with an unsupported error number, do not return a
random pointer but a reasonable text.

59345b1f0f lib: errno: introduce errno_str(): returns errno related message
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
