Depending on `tud_cdc_tx_complete_cb` can cause in some cases the last packet to not be transmitted until more data is written and flushed. It's a rare case, but if the other end is expecting those last bytes, transmission will hang.

This PR also fixes debug output on CDC

This pull request contains a few fixes and improvements to the HWCDC implementation.
- Rework `HWCDC::write()` to accept unlimited data
- Add Semaphore to guard the TX Ring Buffer
- Add events support
- Remove unnecessary 1200bps touch for flashing over HWCDC
- Fix `HardwareSerial::setDebugOutput()` not resetting `putc` if the port is already selected, causing debug output to also show on HWCDC even when not selected.

* Create PULL_REQUEST_TEMPLATE.md

Adding first version of PULL_REQUEST_TEMPLATE.md.

The purpose of this template is to improve and simplify writing more accurate Release Notes.

* Update PULL_REQUEST_TEMPLATE.md

Fix typo.

* Update README.MD - "Type: For reference" labels link

Updating a link to issues labeled with "Type: For reference". The old one is not working due to the updates of labels in the past.

…as component for idf 4.3) (espressif#5599)

esp_eth_phy_new_ksz8081 was added in IDF after version 4.3 and generates a compilation error with IDF-4.3. This change will only use esp_eth_phy_new_ksz8081 for IDF versions after 4.3

* Add an error check for empty path of an URL

* Append '/' to an URL with empty path instead of returning an error

Fix compilation in case NO_GLOBAL_INSTANCES || NO_GLOBAL_SERIAL is defined.

… Allows large MTU to be used. (espressif#5687)

* SDMMC frequency selection based on board type

On Olimex ESP32 EVB I/O operations with SD card can cause error when LAN is used in same time.
Problem is disappearing if SD MMC frequency lower down from SDMMC_FREQ_HIGHSPEED to SDMMC_FREQ_DEFAULT.

No problem if WiFi used instead LAN.

* Code rewritten according to espressif#5688 (review)

* SD.open() new feature for creating all folders in path

This PR adds to the SD.open() function option to create all folders to the file.

SD.open(const char* path, const char* mode, const bool create)

Default value of create is false.
When true folders are created.

From issue espressif#5019

* Update vfs_api.cpp

memccpy -> memcpy

* File f = open() edit

added false for create

* Implement Thread-Safe I2C based on ESP-IDF API

* Update esp32-hal.h

* use proper types for size and timeout

* Allow disabling of the HAL locks

* Limit frequency settings to prevent Interrupt WDT

* Fix build compilation due to changes in the HW_TIMER's structs

* Fix compilation warnings and errors with USB

* Update USBCDC.cpp

* Update CMakeLists.txt

* Update HWCDC.cpp

The client always appends "Basic" to the authorization header, however there are other auth schemes that can be used: https://developer.mozilla.org/en-US/docs/Web/HTTP/Authentication
For example "Bearer" when using OAuth.
This PR adds a `setAuthorizationType` method to the HTTPClient which allows this scheme to be configured by the caller. Authorization type is set to "Basic" by default so this will have no impact on existing usecases.

if (1) log_e("error") produces a warning ("missing braces") and probably wrong code if no log level is defined.
This fixes that.

When using the FTM examples I got an error in the FTM_Initiator.ino:

*"wifi:channel=0 is invalid"*

I solved it for myself by simply passing the channel argument to be 1 in *WiFi.initiateFTM*. However, a better fix would be to directly change the default channel here.

…pressif#5804)

* [FEATURE]  ARDUINO_PARTITION_xxx build flag

Proposition: adding `-DARDUINO_PARTITION_{build.partitions}` flag to make the build partition information available at compile time.

Use cas example:

```C
#if defined ARDUINO_PARTITION_default
  // prevent compilation
  #error "This sketch needs 'Minimal SPIFFS' partition scheme to compile" 
  // or disable sketch features that need flash space
  #define USE_HUGE_BITMAP_IMAGES false
#endif
```

* Adding -DARDUINO_PARTITION_{build.partitions} (see espressif#5804)

Added an option for using precompiled libraries.

Empty if there is no precompilation.

```
compiler.libraries.ldflags=
```

Compiler Message when there is precompilation.

```
Compiling libraries...
Compiling library "aquestalk-esp32"
Library aquestalk-esp32 has been declared precompiled:
Using precompiled library in C:\Users\tanaka\Documents\Arduino\libraries\aquestalk-esp32\src\esp32

The precompiler cannot be used because it is not set up now.

Summary

Only affects ETH (not WiFi)

This PR solves espressif#5733 by allowing the DHCP IDF server to complete its tasks and only then it sets a static IP.
This also solves another related failure reported in this issue (espressif#5733 (comment)).

fix espressif#5733

Impact

Adds a delay in order to wait for DHCP to actually terminate before setting the static IP configuration in ETH.

I misplaced the additions.
