- for all cases of referring guest bootargs size, replace MEM_2K with CONFIG_MAX_BOOTARGS_SIZE for better readability. - remove duplicated MAX_BOOTARGS_SIZE definition from vm_config.h. Also fix one minor issue in general_sw_loader() which uses copy_to_gpa() to copy a string. Since copy_to_gpa() makes use of memncpy_s() to do the job, the size parameter should include the string null ternimator.
