I've gobe for my own mul algorithm for now, and it seems to work for small

positive integers, but it probably needs fixing.

I've added the idiv and mul instructions which are needed by the original PDP-7.
...
However, these are completely untested at the present!

I've added the seek() system call to a7out. I've also added some heuristic code
...
to detect if file output is "binary" or ASCII and to write the file correctly.
Mind you, the heuristic can fail :-( The original cp can now copy ASCII and
binary files.

I've added code to detect binary PDP-7 files to a7out. This is needed

for doing the seek() and tell() syscalls which are next to do.

in src/other/fork_test.s to test it. It's not working quite right
yet, we keep getting wait() returning -1 in a7out even though there
is a child process.
