The public libthermal header opens the C++ 'extern "C" {' block inside
the __LIBTHERMAL_H include guard, but places the closing brace after
the guard has already ended:

	#endif /* __LIBTHERMAL_H */

	#ifdef __cplusplus
	}
	#endif

On a single inclusion the braces still balance, so the problem is
invisible. On the second inclusion of the header in the same C++
translation unit the include guard skips the opening 'extern "C" {',
while the closing '}' lives outside the guard and is emitted anyway.
This leaves a stray '}' and breaks compilation for any C++ consumer
that includes the header more than once.

Move the closing block inside the include guard so both halves of the
'extern "C"' declaration are guarded consistently.
