Merge branch 'bjorn/fix-binary-overflow/OTP-9118' into dev
* bjorn/fix-binary-overflow/OTP-9118: Fix overflow in list_to_bitstring/1 Replace io_list_len() with erts_iolist_size() Make port_command/2 reject non-byte sized bitstrings io.c: Make io_list_vec_len() less general iolist_size/1: Fix truncation of result Test iolist_size/1 with bad arguments binary_SUITE: Remove workaround for avoiding stack overflow
