Updater.cpp:

- use new AutoInterruptLock
 - add delay to give the RTOS some time to handle TCP

WiFiClient.cpp
 - add stopAllexcepted to cancel all TCP excepted one

ClientContext.h
 - add getLocalPort()

ESP8266HTTPUpdate.cpp
 - close all not needed TCP and UDP

osapi.h
 - missing commit from SDK
