prompt as part of guile's primitive language
* libguile/control.h:
* libguile/control.c: Remove scm_atcontrol and scm_atprompt.
(scm_c_make_prompt): Remove handler arg, as the handler is inline.
(scm_abort): New primitive, exported to Scheme as `abort'. The
compiler will also recognize calls to `abort', but this is the base
case.
(scm_init_control): Remove scm_register_control, just have this
function, which adds `abort' to the `(guile)' module.
* libguile/eval.c (eval): Add SCM_M_PROMPT case.
* libguile/init.c (scm_i_init_guile): Change scm_register_control call
into a nice orderly scm_init_control call.
* libguile/memoize.h: (scm_sym_at_prompt, SCM_M_PROMPT):
* libguile/memoize.c (MAKMEMO_PROMPT, scm_m_at_prompt, unmemoize): Add
prompt support to the memoizer.
* libguile/vm-i-system.c (prompt): Fix to not expect a handler on the
stack.
* module/ice-9/boot-9.scm (prompt): Add definition in terms of @prompt.
* module/ice-9/control.scm: Simplify, and don't play with the compiler
here, now that prompt and abort are primitive.
* module/ice-9/eval.scm (primitive-eval): Add a prompt case.
* module/language/tree-il/primitives.scm
(*interesting-primitive-names*): Add @prompt and prompt.
