It raises on EOFError instead of an IncompleteReadError (which is what
CPython does). But the latter is derived from EOFError so code compatible
with MicroPython and CPython can be written by catching EOFError (eg see
included test).
Fixes issue #6156.

Includes a test where the (non uasyncio) client does a RST on the
connection, as a simple TCP server/client test where both sides are using
uasyncio, and a test for TCP stream close then write.
