Constrain constructors and member functions of random number engines so that functions taking seed sequences can only be called with types that meet the seed sequence requirements. PR libstdc++/85749 * include/bits/random.h (__detail::__is_seed_seq): New SFINAE helper. (linear_congruential_engine, mersenne_twister_engine) (subtract_with_carry_engine, discard_block_engine) (independent_bits_engine, shuffle_order_engine): Use __is_seed_seq to constrain function templates taking seed sequences. * include/bits/random.tcc (linear_congruential_engine::seed(_Sseq&)) (mersenne_twister_engine::seed(_Sseq&)) (subtract_with_carry_engine::seed(_Sseq&)): Change return types to match declarations. * include/ext/random (simd_fast_mersenne_twister_engine): Use __is_seed_seq to constrain function templates taking seed sequences. * include/ext/random.tcc (simd_fast_mersenne_twister_engine::seed): Change return type to match declaration. * testsuite/26_numerics/random/discard_block_engine/cons/seed_seq2.cc: New. * testsuite/26_numerics/random/independent_bits_engine/cons/ seed_seq2.cc: New. * testsuite/26_numerics/random/linear_congruential_engine/cons/ seed_seq2.cc: New. * testsuite/26_numerics/random/mersenne_twister_engine/cons/ seed_seq2.cc: New. * testsuite/26_numerics/random/pr60037-neg.cc: Adjust dg-error lineno. * testsuite/26_numerics/random/shuffle_order_engine/cons/seed_seq2.cc: New. * testsuite/26_numerics/random/subtract_with_carry_engine/cons/ seed_seq2.cc: New. * testsuite/ext/random/simd_fast_mersenne_twister_engine/cons/ seed_seq2.cc: New.
