Move sigjmp_buf and jmp_buf structure definitions to machine/setjmp.h so that i386 can continue to use int as the basic register type and alpha can use long. Bruce was concerned about possible differing alignment. I've left the definition of _JBLEN in machine/setjmp.h even though Bruce's example used the number directly. I don't know if any other code relies on _JBLEN, so I left it to avoid potential breakage.
