not accept inexact integers.

* validate.h, deprecated.h (SCM_VALIDATE_INUM, SCM_VALIDATE_INUM_COPY,
SCM_VALIDATE_BIGINT, SCM_VALIDATE_INUM_MIN,
SCM_VALIDATE_INUM_MIN_COPY,
SCM_VALIDATE_INUM_MIN_DEF_COPY,SCM_VALIDATE_INUM_DEF,
SCM_VALIDATE_INUM_DEF_COPY, SCM_VALIDATE_INUM_RANGE,
SCM_VALIDATE_INUM_RANGE_COPY): Deprecated because they make the
fixnum/bignum distinction visible.  Changed all uses to scm_to_size_t
or similar.
