* webui: improve updater error message

* ota: properly check updater state and finalize on errors

* finish up ota handling refactor

* fail web upgrade when cannot find magic byte

* send updater status with no payload arg and always send payload with

* mention magic byte and flash mode in webui

* gzip magic

* make async ota at least usable. timeouts, show errors, try harder to find data after headers

* simplify setup and destruction

* cleanup class instantiations for ota and url

* handle default case of magicflashchipsize

* shorter

* blobs

* web: fix rfb node generator syntax, do not send as basic settings

* ha: allocate discovery object later

- use setOriginalsFromValues function right after elements had changed and
**only** with those elements
- add checkbox handling to setOriginalsFromValues to match hasChanged
- apply hasChanged after value is set to refresh originals after saving
- change parts that already set 'original' attribute manually

This was sort-of broken, because original attr never worked as intended. 
Also fix possible OOM for large WebUI images, since sending full config each time means that we need more memory to buffer and parse it.

- fix colorpicker variable name
- var msg and var pre for debug messages
- add gpio16 to gpio list, remove unused template code
- fix lightfox endif matching rfbridge instead of lightfox
- formatting

- add experimental `relayDummy` to configure dummy relays at runtime
- add tuya-generic-dimmer #1729
- cleanup broker interface to allow Tuya module to properly receive events, modify broker methods to allow different function signatures
- add basic tests for Tuya frame and data protocol

Current gcc-4 does not mark this as warning, but gcc-9 notices the 3 char size requirement. Buffer should be 8

* Use 5000ppm max

* Added restore last schedule support

* Merged RestoreLastScheduleState function into the _schCheck function

* handle lights in restore action

* hide webui chbox when not using scheduler

* use settings instead of struct member, hide under ifdef scheduler_support

* relayLastSchedule uses SCHEDULER_RESTORE_LAST_SCHEDULE as default

* Changed all the variable names to be the same so there would be no confusions

* Fixed client side to create an array from relayLastschedule

* Fixed cosmetic issue with the toggle display in webui

* Fixed variable name and disabled comparison at the end

* Added another check if the switch type is light provider

* Update WebUI

Amend #1843 , since we have updated ESPAsyncWebServer
Fixes (again) #1300

Gather WS debug messages in a buffer and flush every N times
info,keys,crash actually output data now

- update every dynamicjsonbuffer with fixed size constructor argument
- change to ws callback registration to use a class builder (just cosmetic)
- test multiple ws data callbacks for each module
- remove some of the static strings in favour of ws data callback
- improve sensor ws callback data size, remove duplicated strings
- use static buffer in wsDebugSend
- postpone wsSend until loop, implement wsPost to allow other modules to queue message callbacks. remove Ticker based ws callbacks for data
- update WebUI files

- remove optional RFRAW_SUPPORT
- enable module when RF_SUPPORT=1, optionally enable RCSwitch
- reorder ifdef checks to treat RFB_DIRECT and old RF_SUPPORT the same
- rename RF_PIN to RFB_RX_PIN
- depend on RF_SUPPORT instead of ITEAD_SONOFF_RFBRIDGE
- runtime TX & RX PIN setting

1. Add thermostat to the espurna_modules in progmem.h
2. Add thermostat to webui, gulp, html, js.
3. in general.h MQTT_USE_JSON returned to 0 by default and 1 if thermostat enabled.

* Simply print timestamp for supported destinations
* Update ws destination to support 'prefix' sub-key
* Avoid void casting in telnet module

* send all ws config at once on start
* reduce ws json overhead by creating message buffer manually
* use k:[values] instead of k1:value1, k2:value2 etc. for lists
