s_user.c:1428:26: warning: format string is not a string literal
[-Wformat-nonliteral]
Adding the printf attribute to the function will make the compiler
assume that the 'format' argument to the function is a string
literal (by warning about the *callers* of the function *not* using
a string literal), thus avoiding the warning in the function.

- Add (void) casts for unused function parameters
- Rearrange member in `struct rb_mbedtls_cfg_context' for data alignment
- Document a `clang-4.0 -Weverything' (-Wcast-qual) diagnostic
- Avoid pointless conversions between positive/negative error codes
- Use capital hexadecimals in error codes and properly cast to
(unsigned int) for %x/%X
strlcpy should be called with the size of the destination buffer, not
the length of the source string.
When the source is an empty string, the destination buffer isn't
written at all, resulting in it trying to output uninitialised data.
This could also cause a buffer overflow on very long invalid config
lines.
