Fix bug in CombainHttp sending 2 responses for 1 request, add check for waitingForCombainResults all places(race?), don't ifdown wlan1 until Cypress gets back to us

The HTTP thread is now started unconditionally rather than trying to
start it only when required.  Also fixed some formatting issues.

Add Combain service available call (only if api key is set), as soon as scan is done stop wifi client and cleanup some duplicated code

Change GPS/Wifi algorithm, add locationServices to sdef, fix bug in not killing location request, streamline processing

More newlines

Added newline spacing

Add /etc/network/interfaces update for ifup scripts.

combainApiKey modifiable via dhub dynamically, set dhub json string format same for gnss & wifi, i.e.zero for alt & vacc, finally auto-start location

Added dhub config of combain api key if not set from config, default periodic sensor for location to enabled & 30 sec., got rid of exits, tried adding wlan caching (revisit)

The bug that was referenced has been fixed and and a new error flag
definition was created, so use that.

ws_eink: clean up resource by free memory and cleanup deferred io

Using vfree instead of kfree because we using vzalloc to allocate memory
and aff cleanup deferred io

Add locationService to use GPS if available & accurate, otherwise use wifi with Combain service to get location

Update in the background instead of on demand to prevent blocking for
long periods of time.

Add bitrev8 to ws_eink_display for issue mirror with littlevgl graphic lib.

Fix a problem where the OpenWeatherMap ambient temperature service would
try to advertise the service each time a data connection was
established. This caused a crash the second time the connection was
established.
