Log message:
	headers: properly decorate attributes
	
	Found by:
	find -name '*.h' |xargs grep -i 'attribute.*(([a-z]'
	
	For an example of the type of bugs this causes, try compiling this valid
	C11 program (it's valid because 'noreturn' is reserved for use in the
	user namespace unless you include <stdnoreturn.h>):
	
	$ cat foo.c
	#define noreturn __attribute__((noreturn))
	#include <stdlib.h>
	$ gcc -c -o foo.o -Wall foo.c
	In file included from /usr/include/stdlib.h:11:0,
	from foo.c:2:
	foo.c:1:18: error: expected ')' before '__attribute__'
	#define noreturn __attribute__((noreturn))
	^
	/usr/include/stdlib.h:66:28: error: expected ',' or ';' before ')' token
	_VOID _EXFUN(abort,(_VOID) _ATTRIBUTE ((noreturn)));
	^
	
	* libc/machine/spu/spu_timer_internal.h: Decorate attribute names
	with __, for namespace safety.
