Feature/btdm avrc
The source branch "feature/btdm_avrc" includes classic Bluetooth profiles A2DP(sink role) and AVRCP(controller role);
Menuconfig options to control whether to enable classic BT is added.

wifi performance: add wifi performance examples including TCP&UDP TX/RX
Add wifi performance examples including TCP and UDP send and receive.
See merge request !577
request new lines must be `\r\n` as specified in the HTTP RFC.
Also the following logic checks for the socket to be closed by the server. This only happens with HTTP/1.0 not HTTP/1.1. So I have adjusted the protocol in the request, too.
You can set esp32 as AP/STA, client/sever, sender/recever in menuconfig.
You can set whether to display delay time info in menuconfig.
Now you can transfer data between esp and esp.
examples: Standardise naming of files, symbols, etc. in examples
* Use "example" in all example function & variable names,
ie use i2c_example_xxx instead of i2c_xxx for example functions.
Closes#198https://github.com/espressif/esp-idf/issues/198
* Mark example functions, etc. static
* Replace uses of "test" & "demo" with "example"
* Split the UART example into two
* Rename "main" example files to end with "_main.c" for disambiguation

Error handling in NVS initialization
Previously nvs_flash_init worked under an assumption that there should always be at least one free page available. This is true during normal operation, but in some cases (such as when changing application partition table from a non-OTA to an OTA one), NVS partition may get truncated, which will cause empty pages to be lost.
This MR adds error checks for this condition, and updates code which calls `nvs_flash_init` to check for the return code.
For most examples, a simple `ESP_ERROR_CHECK` is added around `nvs_flash_init`. For NVS examples and the OTA example, more robust error handling is added.
This change also removes nvs_flash_init calls from examples which don't use NVS.

1. Add low speed channels for LEDC module.
2. Improve fade object allocate mechanism.
3. Improve ledc example, add 2 low speed channels in example.
4. Remove debug code
5. Improve the register bit field name of slow clock.
nvs_flash_init may return an error code in some cases, and applications
should check this error code (or at least assert on it being ESP_OK, to
make potential issues more immediately obvious).
This change modifies all the examples which use NVS to check the error
code. Most examples get a simple ESP_ERROR_CHECK assert, while NVS
examples, OTA example, and NVS unit tests get a more verbose check which
may be used in real applications.
add wakeup from touch sensor, and deep sleep example
- add new deep sleep wakeup mode
- change documentation to explain incompatibilities between different wakeup mode, add error checks
- add new ULP instructions necessary for ULP wakeup scenario
- fix issues with I_WR_REG, I_SLEEP, I_END instructions
- add deep sleep example, illustrating the use of timer, gpio, touch, and ULP wakeup triggers
See merge request !461
Examples on using capacitive touch sensors
- `touch_pad_read` - read sensor values and show on terminal
- `touch_pad_interrupt` - perform simple calibration; trigger an interrupt when any pad is touched

esptool version bump and new "espefuse.py set_flash voltage" command
* New "espefuse.py set_flash_voltage" command to easily set a fix
VDD_SDIO regulator voltage (1.8V, 3.3V or disabled).
* Fixes bugs when flashing files with non-4-byte aligned lengths
(doesn't effect esp-idf image files)
* esptool README improvements
* Detect overlapping files in write_flash
* read_mac now works correctly on ESP32
* Integrates reset fix for older dev boards (formerly the "Windows ESP32R0 reset workaround")

Allow separate ethernet & wifi configuration
If only 1/2 of ethernet & WiFi are enabled in config, the other interface is no longer linked into the firmware.
* Fixes bug where enabling Ethernet but not WiFi would fail to compile.
* Also means that enabling WiFi but not Ethernet no longer links some unused ethernet interface functions.
See merge request !525
Partition/SPI/OTA docs & OTA new functionality
* Update partition, SPI flash & OTA docs to reflect functionality changes
* Refactor OTA implementation to perform checks mentioned in API doc
* Add new functions to OTA API: esp_ota_get_running_partition() & esp_ota_get_next_update_partition() functions
* Add spi_flash_cache2phys() & spi_flash_phys2cache() functions to support esp_ota_get_running_partition()

1. indicate adv/scan start complete success or failed
2. controller do limit of adv/scan concurrence, so add some codes to report adv/scan start failed or not.
1. add new APIs bt controller enable/disab/deinit
2. make bt controller work need to call two APIs of esp_bt_controller_init and enable
3. modify phy init to make mac reset once
Verify 0xE9 magic byte on first write, verify entire image before
switching.
Enable verification for secure boot signature (was using invalid ifdef
guard)
In the existing tree, after a connected client disconnects the device
will never re-enter the advertising state. Additional clients will not
be able to discover or connect to the device. This patch forces the
device back into the advertising state upon disconnection.
Resolves Pull Request #217https://github.com/espressif/esp-idf/pull/217
Organize examples and API documentation - supplement to !430
This supplement to !430, both intended to replace bulky !421.
1. Fixed broken links
2. Added links to available examples in API documentation, where missing
3. Updated links to point directly to example folder (to show README.md with example description)
4. Added README.md in docs folder info to point reader to ReadTheDocs instead of doc sources, ref. https://github.com/espressif/esp-idf/issues/243
5. Fixed some typo errors / Sphinx warnings
6. Fixed memory leak in example, ref. https://github.com/espressif/esp-idf/issues/209

If using WIFI_INIT_CONFIG_DEFAULT, error message will point out lack
of WiFi. Otherwise linker errors on WiFi symbols should help give a
clue as to what is broken.
Piggy-backs on changes in !420, ref github #230#237
- low level on GPIO12 corresponds to 3.3V output, not 1.8V
- add espefuse.py commands to burn efuses
- add XPD_SDIO_REG to the list of efuses which must be set

component bt:Added the create attribute table method to the new API
GATT Server service table APIs.
Have already modify the style and other things as @jeroen suggestion in other MR(the MR have been closed)

Clean up WiFi & Bluetooth config options
* Splits "WiFi" configuration out from ESP32 configuration submenu to its own menu.
* Renames "BT" to "Bluetooth", enabling Bluetooth is now in this option not the ESP32 submenu.
* Also disables compiling/linking of BT stack if Bluetooth is disabled, saves some build time.
