* Change a #elif by #else

* Move ESPurna Core comment

* Thingspeak: async client fixes

- remove memory management in async client callbacks
- instead of global one, reference asyncclient from callback argument
- transfer temporary data-buffer to the global scope, avoid accidental String copy
- implement strnstr to search onData payload

* fixup format strings

* update retry time each attempt

* start with default attempts value

* trying to work with lwip2-536

- remove bitmask and register struct members

* add a note about changes

* fixup! add a note about changes

* Add support for MagicHome RGBWW LED strip

This adds support for MagicHome 5 channel LED strip. It is using ESP8285 board, labelled as ESP-M4, has 5 powerful MOSFETs (M3006D, up to 80A! continuous/160A peak) at 12-24V. They are driven by smaller transistors. Red LED is connected to 3.3V power supply, and can't be controller. Green LED is connected to GPIO. Pin mappings:
BTN IO0
R Q8 Q2 IO14
G Q6 Q3 IO12
B Q9 Q4 IO13
WW Q10 Q5 IO15
CW Q7 Q1 IO5
GREEN_LED IO2
Looks like the same board is used in another product which has support for RF remote, but mine doesn't, so I don't include RF config, if yours has it should be a simple copy/paste job to add it.

* Add config for push button

* Fix copy/paste mistake

* Turn on/off LEDs using the push button

https://github.com/xoseperez/espurna/pull/1779#issuecomment-504789747

Button is not visible from the outside, but can be wired outside or made more accessible by using a thin object, so it feels more like a button than a hole. The configuration should not cause issues if the button is not used at all.

- chain debugSend_P into basic _debugSend instead of duplicating code, pass va_list between them
- check if new[] call was successful
- when possible, use stack buffer and fallback to heap buffer only when it is more that 64 chars

* fix typo

* debug: heap fragmentation stat

* Rework method detection

- return check integral type as a result of detection instead of method type
- type-tagging instead of enable_if

* fix alias

* typo

* only need one bool_type instance

* Move heap debug into HeapStats header

- don't show fragmentation stats on the first call
- prettify fragmentation display
- pack function params into helper struct

* pass external flag instead

* add missing prototypes

Allow defining custom device name for alexa integration, other than hostname.
Still uses hostname as a fallback.

- store system crash counter and reset reason in rtcmem instead of eeprom
- store relay state mask in rtc in addition to the eeprom
- store relay state in eeprom only when boot mode requires it
- simplify relay state mask calculation / reading using std::bitset
- light state save and restore
- energy total save and restore

- 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

- depend on RF_SUPPORT instead of ITEAD_SONOFF_RFBRIDGE
- runtime TX & RX PIN setting

* Call delay() after callbacks
* Use safer loop delay value

This change adds a second sensor object to deal with two sensors, if BMX280_NUMBER == 2
