This makes readable and writable automatically computed based
on the stream state.
Effectivly deprecating/discouraging manual management of this.
Makes the properties more consistent and easier to reason about.

The syntax of the sentence describing the role of writable.cork() was
unclear. This rephrase aims to make the distinction between writing
to the buffer and draining immediately to the underlying destination
clearer - while keeping performance considerations clearly in mind.

MAX_HWM was added in 9208c89 where the highwatermark was changed to
always increase in steps of highest power of 2 to prevent increasing
hwm excessivly in tiny amounts.
Why a limit was added on the highwatermark is unclear but breaks
existing usage where a larger read size is used. The invariant for
read(n) is that a buffer of size n is always returned. Considering
a maximum ceiling on the buffer size breaks this invariant.
This PR significantly increases the limit to make it less likely to
break the previous invariant and also documents the limit.

The use of dashes -- in general, but especially in our docs -- can be
problematic. It is used inconsistently and there is always another form
of punctuation that is as good or better for the situation. In an effort
to reduce the number of variations we use to display the same types of
information, remove the various uses of dashes from the documentation.

This is work towards resolving the response.finished confusion and
future deprecation.
Note that implementation-wise, streams have both an ending and ended
state. However, in this case (in order to avoid confusion in user space)
writableEnded is equal to writable.ending. The ending vs ended situation
is internal state required for internal stream logic.
