netstack: Refactor tcpip.Endpoint.Read
Read now takes a destination io.Writer, count, options. Keeping the method name
Read, in contrast to the Write method.
This enables:
* direct transfer of views under VV
* zero copy
It also eliminates the need for sentry to keep a slice of view because
userspace had requested a read that is smaller than the view returned, removing
the complexity there.
Read/Peek/ReadPacket are now consolidated together and some duplicate code is
removed.
