* tags.h: move HAVE_STDINT_H handling to scmconfig.h. Move

Browse source 
HAVE_INTTYPES_H handling to scmconfig.h.  #include
"libguile/__scm.h".  Rework handling for scm_t_bits,
scm_t_signed_bits, SCM_T_BITS_MAX, SCM_T_SIGNED_BITS_MAX,
SCM_T_SIGNED_BITS_MIN, and SIZEOF_SCM_T_BITS to use scm_t_intptr,
scm_t_uintptr, SCM_SIZEOF_INTPTR_T, and SCM_SIZEOF_UINTPTR_T, and
SCM_SIZEOF_UNSIGNED_LONG.  Rename usage of HAVE_ARRAYS to
SCM_HAVE_ARRAYS.
