got rid of the Files[] array completely (previously I'd just made it

private to files.c)

It now is a doubly linked list with a bitmap for allocated file
numbers. Similarly for the fd_ptr code. I also changed the default
maximum number of open files to 4096. The static cost is 1 bit per
file.

It all seems to work, and it passes the "does Sue scream" test, but if
you see weird behaviour then please investigate. With the volume of
new code that has gone in there are bound to be one or two bugs
lurking.

note that you must do a "make clean" before building this as many data
structures have changed in size.
