[Sois-tcons] Proposed TCONS API manpage

[Keith Scott]

I have been marking up the red book (mainly section 3.6, the transport layer
primitives and API).  Some issues are:

What to do if the incoming data unit is larger than the buffer supplied by
the application?
Making sure we always give the application the length of the various data
items (particularly payload items).
Do we want to be able to cancel receive requests (or send requests before
the callback is invoked)?
