* 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

* create varient for magicbit board

* update boards.txt

Added more menu settings for TinyPICO - Fash mode and Flash speed. Set Flash mode default to QIO (#2976)

Fixed bit shift in demo application of using RMT peripheral. Init data array to be transmitted was off by one, as for the first iteration (i==0) the mask was 1<<8, which results in shifted RGB value in color variable
Closes https://github.com/espressif/arduino-esp32/issues/2921

* Config fix test

* Also force config even if equal

* Update boards.txt

Adding ESP32-WROOM-32 8MB flash option

* Update boards.txt

Fixing partition size and typo

* Update boards.txt

* WiFiClient.cpp - Fix connect() behavior

* lwip_connect_r() : check return code

* Added convert method to transfer data from partition to nvs

* Could have sworn I changed the return when I made the label

* Empty state should be 0xFF.  Fixed some logging levels

* Set result on success

The flush causes an empty response a client side.

see https://github.com/espressif/arduino-esp32/issues/2902

* BLEServer::disconnect()

* Invoke Read callback first, to make data update possible before read

* Remove partitioning comments

* Revert "Remove partitioning comments"

This reverts commit b3b03a81572d352816819cff772231ba037dc338.

* Removed partitioning comments from EEPROM example

* std::stringstream -> std::string

* Fix small issues

* Small fix 2

* Expand gitignore to cover files created by Visual Micro's Arduino IDE for Visual Studio

(cherry picked from commit d6209c79ea16a26564fe27e74e5f277160129847)

* Also ignore VS project files

(cherry picked from commit e0ec212bd41e75a3570a6098a66ee66787db58db)
