Print system calls and arguments similar to the 'strace' program
(NOTE: the actual 'strace' program will not work because the user
space emulator hasn't implemented ptrace). At the moment this is
incomplete. All system calls that don't have a specific argument
format are printed with information for six arguments. Many
flag-style arguments don't have decoders and will show up as numbers.
