4f2ba9fbdc esp8266: Convert to use new MP_Exxx errno symbols. 
These symbols are still defined in terms of the system Exxx symbols, and
can be switched to internal numeric definitions at a later stage.

Note that extmod/modlwip still uses many system Exxx symbols.

82b95f625e esp8266: Implement software SPI class. 
Supports speeds up to 500k baud, polarity=0/1, phase=0/1, and using any
pins.  Only supports MSB output at the moment.
