Start to use C99 stdint in gen-scmconfig

* configure.ac: Remove checks for stdint.h; we require C99 so it must be
  there; and in any case for our purposes we use gnulib, so it will be
  there.  No need to check for inttypes.h.  No need to check for what
  type maps to e.g. uint32_t either.
* libguile/deprecated.h (SCM_HAVE_T_INT64, SCM_HAVE_T_UINT64): Deprecate
  these, as they are always 1.
  (SCM_HAVE_ARRAYS): Likewise deprecate; it's always 1.
* libguile/gen-scmconfig.c: Always include stdint.h and stddef.h, and
  make it so that scmconfig.h also includes these.  Use C99 types.
* libguile/gen-scmconfig.h.in: Remove configure-substed vars that are no
  longer defined.
