Includes all the latest NimBLE stack changes from idf-v4.0 with few idf-v3.3
specific modifications.
- Addition of nimble component as submodule (`nimble-1.1.0-idf-v3.3`), contains
IDF v3.3 specific minor changes.
- Example applications are identical to idf-v4.0
- Modification in `bt/Kconfig` to accommodate NimBLE as a BT host.
List of changes in components/wifi_provisioning:
* Manager version is now v1.1
* .proto files and protocomm handler added for sending Wi-Fi scan command and receiving scan results
* Implemented handlers for wifi_scan protocomm endpoint
* Update manager context data structure to hold scan state and results
* scheme_softap now runs Wi-Fi in APSTA mode
* Wi-Fi is started in AP mode when provisioning is started. This is necessary for scan list to work
* Docs updates with information about new wifi_scan endpoint
List of changes in tools/esp_prov:
* Added functions for sending and receiving protobuf messages compatible with wifi_scan protocomm endpoint
* Added feature to display/refresh scan results and accept user selection at runtime
* New functions:
* get_version() : only returns the protocol version string
* has_capability() : check is a capability is present according to proto-ver response
* wifi_scan feature is provided only if the `wifi_scan` capability is present
Other changes:
* Replace recursive mutex with plain mutex
* assert on return value of mutex give / take calls
* replace all calls with macros ACQUIRE_LOCK and RELEASE_LOCK
* some checks added in scanning related private APIs
* free and nullify scanning context and state if service is stopped while ongoing scan
docs: This is a quick reference of more than a dozen and-ons and extensions prepared over the last two years to add contents, improve look & feel and cut on maintenance of the ESP-IDF documentation.

This commits adds the functions can_clear_transmit_queue() and
can_clear_receive_queue(). Closes#2906
The following bug are fixed:
- CAN_IO_UNUSED is now explicitly cast to enum type. Closes#2825
- Fix multiple documentation errors. Closes#2898, Closes#2794
- can_reconfigure_alerts() returns incorrect current_alerts. Closes#3028
- Add missing header file. Closes#3065
Added:
* set a secure version in app/bootloader.
* description anti-rollback to ota part
* emulate the secure_version write and read operations
* efuse_em partition.
* a description about a rollback for native_ota_example.
Closes: TW26335
This will be useful if a webserver is already running and the application
does not want protocomm to start a new instance.

Added a new structure esp_app_desc_t. It has info about firmware:
version, secure_version, project_name, time/date build and IDF version.
Added the ability to add a custom structure with a description of the firmware.
The esp_app_desc_t is located in fixed place in start of ROM secotor. It is located after structures esp_image_header_t and esp_image_segment_header_t.
app_version is filed from PROJECT_VER variable (if set in custom make file) or PROJECT_PATH/version.txt or git repo (git describe).
Add API to get app_desc from partition.
The DMA cannot receive data correctly when the buffer address is not
WORD aligned. Currently we only check whether the buffer is in the DRAM
region.
The DMA always write in WORDs, so the length arguments should also be
multiples of 32 bits.
A check is added to see whether the buffer is WORD aligned and has valid
length.
Introduced in 9c23b8e5 and 4f87a62f. To get higher speed, menuconfig
options are added to put ISR and other functions into the IRAM. The
interrupt flag ESP_INTR_FLAG_IRAM is also mistakenly set when the ISR is
put into the IRAM. However callbacks, which are wrote by the user, are
called in the master and slave ISR. The user may not be aware of that
these callbacks are not disabled during flash operations. Any cache miss
during flash operation will cause panic.
Essentially IRAM functions and intrrupt flag ESP_INTR_FLAG_IRAM are
different, the latter means not disabling the ISR during flash
operations. New bus_config flag intr_flags is offered to help set the
interrupt attribute, including priority level, SHARED, IRAM (not
disabled during flash operations). It introduced a small BREAK to
IDFv3.1 (but the same as IDFv3.0) that the user has to manually set IRAM
flag now (therefore he's aware of the IRAM thing) to void the ISR being
disabled during flash operations.
