2a326134d0 Add a -s flag for the same functionality as strace. Introduce a Name
type which is a String type that has no -s limitations applied to it.
Change most Strings in the code to Names and add a few extra syscalls,
namely munmap, read, rename and symlink.  This was enough to facilitate
following file descriptor allocations in the code more easily and
getting a hint at what's being read/written from/to files.  More
syscalls should really be added.

While here, fix an off-by-one bug in the buffer truncation code and
add a fflush so that truss's output reflects the syscall that the
program is stuck in.

f770c48d15 Support readlink(2) better. Readlink does not nul terminate the
result buffer, so we need to format it ourselves.  The problem is
that the length is stored as the return value from readlink, so we
need to pass the return value from our syscall into print_arg.

Motivated by: truss garbage on my screen from reading /etc/malloc.conf.

cfc5f034d6 A first stab at truss support for amd64, basically cogged from i386.
It seems to work in my limited tests.
