all uses of vp with this.
As the FSF advises, 'There is no legal significance to using the
three-character sequence “(C)”, but it does no harm.' It does take up
space though! For that reason, we remove it here from our C files.
* libguile/__scm.h (scm_i_jmp_buf): Remove definition, which was a shim
for ia64. Instead, always use setjmp/longjmp and jmp_buf.

capture_auxiliary_stack.
* libguile/threads.h (scm_i_thread): jmpbuf member is plain jmp_buf.

calling ops.
