81a3e2b46d Add a convenience macro for the returns_twice attribute, and apply it to
the prototypes of the appropriate functions (getcontext, savectx,
setjmp, sigsetjmp and vfork).

747ba408ec Fix namespace issues by using visibility conditionals from
<sys/cdefs.h>.  Sort function prototypes.

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.

8e6eb00a8e Move _JBLEN definition to <machine/setjmp.h> like on NetBSD. Remove
definitions for architectures that we don't have libc MD source for.

Change 'int' to 'long' in sigjmp_buf and jmp_buf structures so
that they are suitable for the register size on both i386 and alpha.
Although FreeBSD defines these structures differently to NetBSD,
the element size is now the same.

If Bruce doesn't like this [8-)], we'll need to add a typedef to
each <machine/setjmp.h> and use that in <setjmp.h>.

6ed5ccfb8f Don't use __dead or __pure in user code. They were obfuscations
for gcc >= 2.5 and no-ops for gcc >= 2.6.  Converted to use __dead2
or __pure2 where it wasn't already done, except in math.h where use
of __pure was mostly wrong.

73fd6b51c8 Delete vax' (and i386' and `hp300' etc.) namespace pollution.
Our one supported compiler always defines the double-underscore variant,
so always use that.

Noticed by Bruce Evans after a report by John Capo.

7766663139 Improve error detection and handling:
Reduce _JBLEN for the i386 to what is actually used.
	Encapsulate jmp_buf and sigjmp_buf in structs.
	Enlarge jmp_buf to the same size as sigjmp_buf.
	Declare *longjmp as non-returning.

Remove stale comments about sig*jmp not being implemented.
