features of mmap that the standard test uses, and it reports Ultrix as
having no working mmap() when in fact any mmap will do what we want
for rsync.

The compressed token code now handles the null (-2)
token from the match logic.

1) handle 64 bit file offsets in the token code. I wonder how large
bit files worked up till now?

2) send a null token when we have passed over a large lump of data
without finding a token match. This reduces the number of IOs
considerably as it removes the need for seeks/reads on the checksum
calculation and literal send code. This is not enabled yet for the
compressed case as the deflate token code can't handle it yet.

token changes.

and thus consume less virtual memory on the sending side.

I've doen a fair bit of testing and I don't seem to have broken
anything, but it is a very complex change. More testing needed!

growing too much if the sender is much faster than the receiver

where a rsync receive process could hang around after the connection
has gone away if a fatal error occurs (such as someone killing the
other end)

this stops "rsync -v" causing a segv.
