05852bc4aa protocomm_httpd: Restart security session if request is received on a new session
This commit fixes a bug as well as changes a behaviour.

Bugfix: During softap/httpd based provisioning, if a session was closed
midway and a new one started, it would never proceed if the http server
assigns same socket number to the new session (which happens almost always).
Now, if a session is closed, using the http callbacks, the older session
data is cleared so that a new one can be created.

Behavioural change: If a client (mobile app particularly) does not use
persistent http session i.e. all provisioning communication on the same
socket, the provisioning may fail. Earlier, since the session context was
not getting cleared, even if the client closed a session and continued
on a new one, it would go through if the socket number assigned was same
(which happens almost always).

Ideally, from a security perspective, all communication related
to secure provisioning must happen on the same socket, and so, this
change is required.

388b350f0d NimBLE-provisioning: Add NimBLE support to unified provisioning framework
- Adds NimBLE stack support to existing BLE variant of unified provisioning.
- Uses scan response to send device name, 128 bit custom UUIDs based on service
  UUID.
- Minimal changes to `app_prov.c`, component.mk, CMakeLists.txt and
  `protocomm_ble.h` to accomodate NimBLE stack for provisioning.

120bd3a456 protocomm_ble : Fixed custom service UUID support
List of changes:
* Use 128 bit characteristic UUIDs when creating GATT table entries
* Change primary service attribute value to 128 bit custom service UUID
* Use raw advertisement data to convey flags and 128 bit primary service UUID
* Use raw scan response to send device name as complete local name
* Increase maximum device name length in relation to maximum scan response length
* Set Characteristic User Description attributes for each characteristic to convey protocomm endpoint names

86e9acc2c9 Protocomm : Added new APIs for opening and closing secure sessions
New APIs:
* protocomm_open_session()
* protocomm_close_session()

This allows external applications using protocomm to manually create and close sessions.

These internally call the new_transport_session() and close_transport_session() APIs implemented by the security scheme in use.

Updated unit tests with usage of new APIs

cccf829366 Protocomm : Session security now supports multiple instances of the same type
List of changes:
* Security APIs accept handle to instance created during initialization
* Protocomm internally stores the security instance handle and calls security APIs with this handle as first parameter

a717825b7e Unified Provisioning: Miscellaneous fixes in BLE
1. Pass the correct conn_id to protocomm_req_handle
In transport_simple_ble_write(), passing param->exec_write.conn_id would
be invalid. Instead param->write.conn_id should be passed
Similar change in transport_simple_ble_exec_write() to use
param->exec_write.conn_id

2. simple_ble_start() assumes that the mode is BLE only and enables
Bluetooth controller accordingly. For, cases having BT + BLE like Alexa
(Provisioning over BLE + Audio over classic BT), this assumption should
be removed.

a1d37c833c protocomm : version endpoint behavior simplified
List of changes:
* Version endpoint now sends the set version string instead of verifying the incoming version string. This simplifies fetching version info from the provisioning application.
* esp_prov script updated to expect version string as response.

d0c777b2e1 Protocomm : Added component core for protocol communication
* This manages secure sessions and provides framework for multiple transports.
* The application can use protocomm layer directly to have application specific extensions for provisioning (or non-provisioning) use cases.
* Following features are available for provisioning :

  * Security - Security0 (no security), Security1 (curve25519 key exchange + AES-CTR encryption)
  * Proof-of-possession support for Security1

* Protocomm requires specific protocol buffer modules for compilation which can be generated from the `.proto` files in the `proto` directory using make.
