Kenneth Finnegan 98ad16eff8 Correct buffer overflow and remove magic constants from esp8266 example ...

The msg[] array is defined as 50 bytes long, but then the snprintf is
protected at 75 bytes long, which is incorrectly 25 bytes longer than
the underlying array.

To correct this, define a new macro MSG_BUFFER_SIZE and use it in both
places:
 * defining msg[]
 * writing to msg[] with snprintf()
