Some architectures will pretty-print a system call trap in the backtrace. Rather than printing the symbol, use the syscallname() function to pull the string from the sv_syscallnames array corresponding to the process. This simplifies the function somewhat. Mostly, this will result in dropping the "sys" prefix, e.g. "sys_exit" will now be printed simply as "exit". Make two minor tweaks to the function signature: use a u_int for the syscall number since this is a more correct type (see the 'code' member of struct syscall_args), and make the thread pointer the first argument. The latter is more natural and conventional.
