bignum.c, numeric.c: add Integer#pow(b, m)

This commit is based on the pull-request #1320 created by Makoto Kishimoto.
[Feature #12508] [Feature #11003] [close GH-1320]

  • bignum.c (rb_int_powm): Added for Integer#pow(b, m).

  • internal.h (rb_int_powm): Declared to refer in numeric.c.

  • bignum.c (bary_powm_gmp): Added for Integer#pow(b, m) using GMP.

  • bignum.c (int_pow_tmp1): Added for implementing Integer#pow(b, m).

  • bignum.c (int_pow_tmp2, int_pow_tmp3): ditto.

  • internal.h (rb_num_positive_int_p): Moved from numeric.c for sharing
    the definition with bignum.c.

  • internal.h (rb_num_negative_int_p, rb_num_compare_with_zero): ditto.

  • numeric.c(negative_int_p): Moved to internal.h for sharing the
    definition with bignum.c.

  • numeric.c (positive_int_p, compare_with_zero): ditto.

  • numeric.c (rb_int_odd_p): Exported (renamed from int_odd_p).

  • internal.h (rb_int_odd_p): ditto.

  • internal.h (HALF_LONG_MSB): Added.

  • numeric.c (SQRT_LONG_MAX): Redefined by using HALF_LONG_MSB.

  • test/ruby/test_numeric.rb (test_pow): Added for Integer#pow(b, m).
