As it turns out machine_name_is_valid() does the exact same thing as hostname_is_valid() these days, as it just invoked that and checked the name length was < 64. However, hostname_is_valid() checks the length against HOST_NAME_MAX anyway (which is 64 on Linux), hence any additional check is redundant. We hence replace machine_name_is_valid() by a macro that simply maps it to hostname_is_valid() but sets the allow_trailing_dot parameter to false. We also move this this call to hostname-util.h, to the same place as the hostname_is_valid() declaration.
