1. Why not use ansi prototypes to simplify the formatting?
2. In 3.2.3, show the compat_30_sys_sockets_args structure and explain
   the SCARG() macro.
3. In 3.2.6, mention that we usually implement the older version of the
   syscall in libc so that we can provide binary compatibility for
   dynamically linked libraries without needing the kernel support.
   Also mention that we don't litter the code with compat defines,
   but we put stuff in lib/libc/compat or sys/compat. Mention how
   __RENAME() works and the __LIBC12_SOURCE__ define.
