With send(...) changing to non-block, modem can be busy in sending previous data and 'busy' the current 'AT+CIPCLOSE' command.
In blocking mode, add retries to avoid spurious close to some degree.
This is required to pass GT netsocket-tcp/netsocket-tls tests which expect close(...) to be OK.
PAE supplicant did not detect correctly that network name or PAN ID
was changed on authentication start. This causes the supplicant to
use old keys and old BR EUI-64 during authentication, which resulted
to BR EUI-64 mismatch on 4WH.
This is because the ESP8266 is now waiting for SEND OK and takes much
more to complete the send_repeat, and echo_burst tests in RAAS.
(but has higher pass ratio).
1. Fix 'spurious close' by adding close() in open(). 'spurious close' gets frequent and cannot ignore when send() changes to asynchronous. User can retry open() until 'spurious close' gets true.
2. Allow only one actively sending socket because:
(1) ESP8266 AT packets 'SEND OK'/'SEND FAIL' are not associated with socket ID. No way to tell them.
(2) In original implementation, ESP8266::send() is synchronous, which implies only one actively sending socket.
3. Register 'SEND OK'/'SEND FAIL' oobs, like others in ESP8266::ESP8266 constructor. Don't get involved in oob management with send status because ESP8266 modem possibly doesn't reply these packets on error case.
4. Now that ESP8266::send() changes to asynchronous, drop the code with _parser.recv("SEND OK")/_parser.recv("SEND FAIL"). _parser.recv("SEND OK")/_parser.recv("SEND FAIL") and 'SEND OK'/'SEND FAIL' oobs both consume 'SEND OK'/'SEND FAIL' packets and complicate flow control.
We are now checking if ESP8266 has confirmed receiving data over serial
port with an undocumented (but existing) "Recv x bytes" message. Next we
are explicitly waiting for an official "SEND OK".
