add with-fluids objects and primitive syntax
* libguile/tags.h (scm_tc7_with_fluids): Allocate a tc7 for
"with-fluids" objects, which will only live on the dynamic stack (wind
list), not in normal scheme-land.
* libguile/fluids.h (SCM_WITH_FLUIDS_P, SCM_WITH_FLUIDS_LEN)
(SCM_WITH_FLUIDS_NTH_FLUID, SCM_WITH_FLUIDS_NTH_VAL)
(SCM_WITH_FLUIDS_SET_NTH_VAL): Add some accessors.
* libguile/fluids.c (scm_i_make_with_fluids, scm_i_swap_with_fluids):
New internal functions.
(scm_c_with_fluids, scm_c_with_fluid): Push with-fluids objects on the
dynwind list, not winders.
* libguile/dynwind.c (scm_i_dowinds): Add cases for winding and
unwinding with-fluids objects.
* libguile/memoize.h (scm_sym_with_fluids, SCM_M_BEGIN): New public
data.
* libguile/memoize.c (scm_m_with_fluids): Define with-fluids as a
primitive syntax.
(unmemoize): Add with-fluids case.
* libguile/eval.c (eval):
* module/ice-9/eval.scm (primitive-eval): Add with-fluids cases.
* test-suite/tests/fluids.test
("fluids not modified if nonfluid passed to with-fluids"): Enable a
now-passing test.
