geeksville 2996c7c8e2 Make tcp API now work. Sample usage and caveats below:
Sample usage:

First configure device to use @mc-hamster's new wifi stuff:
meshtastic --set wifi_ssid mylanname --set wifi_password mylanpassword

Then reboot the device (so wifi starts up).

(assuming device was assigned addr 192.168.81.45)
meshtastic --info --host 192.168.81.45
(See the usual device info you previously had to get over USB)

Caveats:

* Currently we are limiting to one active TCP connection open at once, if
you open a new session the old one is closed automatically
* There are no access controls/authentication needed to open a TCP
connection to the device
* Currently main.cpp is kinda dumb about how we should schedule work and
we rely on too many helper loop() functions.  Very soon in my queue
(related to all the other cleanup) is to add a basic notion of coroutines,
so that we can get away from freertos threads and this old school arduino
loop function.  Once that cleanup happens we can the a) have much lower
battery consumption (always) and b) super fast response for all operations.
