The uos.dupterm() signature and behaviour is updated to reflect the latest enhancements in the docs. It has minor backwards incompatibility in that it no longer accepts zero arguments. The dupterm_rx helper function is moved from esp8266 to extmod and generalised to support multiple dupterm slots. A port can specify multiple slots by defining the MICROPY_PY_OS_DUPTERM config macro to an integer, being the number of slots it wants to have; 0 means to disable the dupterm feature altogether. The unix and esp8266 ports are updated to work with the new interface and are otherwise unchanged with respect to functionality.
