mqtt: bump arduino-mqtt version, tweak keepalive

* Check patched RFM69 with relative includes

* merged upstream, point to the commit

see https://gitter.im/tinkerman-cat/espurna?at=5e44563355b6b04bf6aac94b

- continue #2140 , use the correct implementation for http requests not confuse code readers with our parsing
- fix data sender data duplication, run build test
- add note that this is actually really RAM heavy, some connection failures are not easily distinguishable from any code errors and are simply OOM.

also
- fix arduinoota prototype error when building without it (... ino2cpp, again)
- add comment about 160mhz into the platformio.ini

* Revert "Fix AsyncTCP dependency (#2147)"

This reverts commit d5093b4d18.

* Ignore AsyncTCP

PIO 4.2.1a default soft does not work

We would be thankful if you could use a development version of PlatformIO Core. in 99.999% it's very stable but there sometimes the cases which we didn't expect, such as https://github.com/platformio/platformio-core/issues/3377

So, if you will see any issues with PlatformIO Core-dev, please report us and we will fix ASAP. Thanks!

* Permit thingspeak urn edit

* Update thinkspeak.ino

* Update index.html

* Replace Host, Port, and URL with Address in Thingspeak

* Create AsyncThingspeak object

Create AsyncThingspeak object to contain the url of the component.

* replace pointer by class member

Thingspeak class improvement to answer Max's question:
why use a pointer when it can be a class member?
So now address parameter isn't a pointer anymore.

* Update Thingspeak address on post

Fallback to basic N seconds display when disabled

* Config: remove prototypes.h

* fixup order

* word

* add missing

* fix warning while still using .ino

* bad at c/p;

* ntp: try using sntp app from lwip, drop ntpclientlib

* fix display

* thermostat: fix day and month getters

* test build sizes with scheduler

* use system timers for once-a-minute scheduling, no polling

* tick

* avoid timestamps, use tm

* drop utc rpn operator, add utc_hour and utc_dow

* try to build with old implementation too

* dep

* notify ws

* progmem

* cleanup types

* offset tm values by 1 to match existing schedules

* avoid using ntpclientlib with rpn

* test. show debug strings in sch

* fix secureclient

* consts, fix unsyncing when changing tz (and not triggering sntp after reinit for some reason)

* startup time in seconds

* same delay as lwip

* header

* assume build timestamp is unixtime

* cache server value

* fmt

* typo

* handle dhcp request

* rename

* web

* TZ.h

* add notice about what alias means

* fix disabling NTP_SUPPORT

* scheduled ticker

* same behaviour as old module

* rollback rpn dependency check, utc_ prefixes

* ...

* comments, refactor naming

- add ltDimmerGPIO<index> & ltDimmerInv<index> to override / add to hardware configuration. Add pin defaults, mapped as GPIO_NONE. pwm_init() receives resulting GPIO mapping based on settings loader.
- remove bogus _light_channels variable, use this name for channel array instead (...which is vector and has size(). functions always use that value anyway)

Fix UnixHostDuino dependency

* Sensors: refactor configuration

- move sensor implementaion to the .ino,
  remove dependency undef / define from sensor files
- update test/build/sensor.h from SENSOR_SUPPORT
- allow to change sensor config variables externally
- `#include <...>` for global headers and libraries,
  fix relative path for math library

* add missing sns <-> i2c dependency

* ledrelay should return relay_none as default

* rollback to original test header

* include debug header when requested (relative)

Static configuration for LED & Buttons

- use similar to relay & wifi, configuration through helper methods that
  use indexed defines
- clock cycles for led delay polling
- button mode defaults

* debug: log mode, allow to skip boot messages

* typo, fix warning about unhandled switch

* mention telnet wifiserver & reverse changes

* PIO: remove -ota envs, handle OTA condition in extra script
* Tweak ESPURNA_BOARD variable
* Support git and latest in ota script
* Handle ESPURNA_FLAGS too
* Try to handle env and projenv in pylint
* Add deprecation comment about -ota envs
* regen arduino.h

* experimental: refactor get/set/del/hasSetting

* sensors

* lights

* cleaup

* r

* tuya

* fixup! sensors

* fixup! tuya

* header defaults types

* fix lights

* setup already checks for max

* helper for flashstring

* fix overload

* oops

* refactor includes

* warnings

* test with migrate

* add ids in a separate file

* cleanup
