* Added timeout to WiFiScan class to prevent haning at stucking at WIFI_SCAN_RUNNING when scan fails internally

* fixed tabs and returns, connected scanTimeout to max_scan_per_channel timeout

* Corrected tabs two

* Added static vars scanTimeout und scanStarted to WiFiScan.h protected section

* Fixed missing ; in line 64

Relative to #3006

* Inline ESP::getCycleCount() to make it safe to call from ISRs

* Attribute IRAM_ATTR ISR-safe function in addition to inlining.

* Fix wrong values in .cvs files

Add missing upload size for partitions bigger than default one

* Add new partion to generic

Fix hardcoded partition for 16M flash

* Expose uartStartDetectBaudrate(uart_t *) in esp32-hal-uart.h and call it from HardwareSerial::begin() if baudrate detection is requested (by passing a baudrate of 0) to solve baudrate detection problems

* Avoid a division by zero error in uartGetBaudRate()

* Use loc_buf for small strings, check for error return from vsnprintf

* cleanup arg when bailing out of new

* Use malloc/free instead of new/delete in printf

* Return actual bytes written in printf

* FIX: write before free

Pointing to an old fork is misleading.

Some ESP32 chips are rated only to 160MHz. This change adds support for them and does not allow frequency to be switched to 240MHz

* Fix long Ticker period conversion

* Simplify long Ticker period conversion fix by using 1000ULL

* Rework the sketch builder to match the IDE

* Link the board to the home folder

* Rename files for clarity

* move ci files to own subfolder

* Update Github CI to use the new script locations

Fixes #3140

* Removed pragme in BLERemoteService.cpp

* Added the line at the top and changed to warning

* Fix persistance issue found, see ESP8266 issue #6152

* Correcting the parsing of the header for HTTP1.0

* Send 'Connection: Close' header in case of HTTP1.0

* Let reuse connection depend on protocol used: HTTP1.0 or HTTP1.1

* Fixed reuse, added null ptr checks, added check for _trainsportTraits in connect() in case _client was set null

* Fix reuse connection issues, similar to ESP8266 PR #6176

* add timed wait

* Added Notification/Indication data and status callbacks

* imply null-object pattern for BLE callback

* ESP.getCpuFreqMHz was returning the CONFIG_ variable.  Now calls the getCpuFrequencyMhz function.

* Changed the Esp function to uint32_t to match

more secure

The progress callback was only invoked with Update.writeStream before

BLEAdvertising::handleGAPEvent -> ESP_GAP_BLE_ADV_STOP_COMPLETE_EVT should NOT call start()!

* Add generic IP calculations

Add:
calculateNetworkID(IPAddress ip, IPAddress subnet) => Calculate the network id using the ip and subnet (e.g. 192.168.0.0)
calculateBroadcast(IPAddress ip, IPAddress subnet) => Calculate the broadcast ip using the ip and subnet (e.g. 192.168.0.255)
calculateSubnetCIDR(IPAddress subnetMask) => Calculate the subnet CIDR using the subnet (e.g. 24)

Add:
broadcastIP() => Retrieve the network id (e.g. 192.168.0.0)
networkID() => Retrieve the broadcast IP (e.g. 192.168.0.255)
subnetCIDR() => Retrieve the subnet CIDR (e.g. 24)

Add:
broadcastIP() => Retrieve the network id (e.g. 192.168.0.0)
networkID() => Retrieve the broadcast IP (e.g. 192.168.0.255)
subnetCIDR() => Retrieve the subnet CIDR (e.g. 24)

Add:
softAPBroadcastIP() => Retrieve the network id (e.g. 192.168.0.0)
softAPNetwrokID() => Retrieve the broadcast IP (e.g. 192.168.0.255)
softAPSubnetCIDR() => Retrieve the subnet CIDR (e.g. 24)

Only space for 1 characteristic is allocated, requesting 10 leads to stack corruption.

* add core installation 1.0.2

* added 1.0.3

#2891

* Updated magicbit variant

* Added LED_BUILTIN
