move *longjmp related prototypes to setjmp.h

Provide common prototypes for __longjmp, __libc_longjmp, __libc_siglongjmp
_longjmp_unwind, __libc_unwind_longjmp in setjmp.h in preparation for use in LT new
Add __longjmp to h8300 and i960
Make common longjmp.c good for NPTL
Guard _longjmp_unwind use in sh's longjmp.c for NPTL (I think sh could use the common one)
Remove unneeded attribute_noreturn, prototype provides it already
