add "memoizer" data type
* libguile/memoize.h:
* libguile/memoize.c (MAKMEMO_APPLY): Take the proc and args separately.
(scm_tc16_memoizer, SCM_MEMOIZER_P, SCM_MEMOIZER): New smob type, for
"syntax" like @apply that have normal evaluation order.
(memoize_env_ref_macro, memoize): Refactor to handle "memoizers"
generically.
Reorganize the list of SCM_SYNTAX forms.
Move @apply, @dynamic-wind, @call-with-current-continuation,
@call-with-values, @prompt handling down to be generic "memoizer" data
types.
(scm_memoizer_p, scm_memoizer): New functions, exposed to Scheme. Will
be used by psyntax.
