* Allow overriding telnet port + max clients

* Do not allocate 512 bytes by default

* Use TERMINAL_BUFFER_SIZE

* Implement suggestion from Max Prokhorov, it's simpler and cleaner

* Change a #elif by #else

* Move ESPurna Core comment

* Use basic BearSSL ciphers on low memory boards

* Move BearSSL basic flag to recommendation

- update file paths: .pioenvs -> .pio/build, .piolibdeps -> .pio/libdeps
- modify envs to use common settings
- enable shared libs in travis and ota scripts

* PlatformIO development platforms

* Properly detect platform directory

* Naming

* Update platformio.ini

* 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

* count time from last request

* promptly run flush

Fix random resets when connection closes prematurely

* Update encoder

- import modified Encoder library
- customize minimum delta value

* minimum delta in header config

* fixup! minimum delta in header config

* fix dead code, actually use interrupts

* move static class methods to normal funcs, apply namespace

* drop hardcoded register use

- use peripheral api (see cores/esp8266/esp8266_peri.h)
- 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

- cache ms<->clockcycles conversions
- move callback invocation outside of ISR handler
- remember last event value

* Update crash handler

- limit recorder stack size by 128 bytes
- offset settings a bit more
- add possibility to disable crash crash recoder completely

* nicer setting names, comment layout change

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.

* Configure WEB_REMOTE_DOMAIN at runtime

* typo

* Added ability to print all GPIO values at once

* Print input/output pin state, optimize code

- 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

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