Avoid truncated POST bodies from with URL-encoded forms in Rails
by switching TeeInput to use read-in-full semantics (only) when
a Content-Length: header exists.  Chunked request bodies
continue to exhibit readpartial semantics to support
simultaneous bidirectional chunking.

The lack of return value checking in Rails to protect against a
short ios.read(length) is entirely reasonable even if not
pedantically correct.  Most ios.read(length) implementations
return the full amount requested except right before EOF.

Also there are some minor documentation improvements.
