we no longer use non-blocking IO, instead it uses select a lot more,

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.

cache friendly.

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!
