The previous "using_mbedtls_pkcs11.c" implementation requires using the device key and device certificate stored under the labels "pkcs11configLABEL_DEVICE_PRIVATE_KEY_FOR_TLS" and "pkcs11configLABEL_DEVICE_CERTIFICATE_FOR_TLS".
This commit updates the NetworkCredentials to include fields for pClientCertLabel and pPrivateKeyLabel, so other labels can be used with PKCS11. This matches the behavior seen in the CSDK.
This commit also updates the "pkcs11_mqtt_mutual_auth_demo" to set the newly-added NetworkCredentials fields.
Move the contents of FreeRTOS/FreeRTOS-Plus/Source/Application-Protocols/network_transport/using_mbedtls/

Issue
The existing clock discipline algorithm in the coreSNTP demo yields an inaccurate wall-clock time (in UTC) that is always behind the astronomical UTC time by the chosen polling interval period of the demo. The issue with the clock discipline algorithm was that it was calculating the slew rate to make the system clock be gradually compensated for the previous time synchronization clock drift over the period of the subsequent polling time interval. Thereby, the clock slew rate correction calculated is always lower than it should be (because it does not incorporate possible clock drift that would occur over another period of time polling interval till the next time synchronization attempt).
Fix
This PR fixes the clock discipline algorithm to make the demo calculate its system time that matches the astronomical UTC time.
The fix involves simplifying the clock discipline algorithm to use a combination of step and slew correction approaches where:
1. Step correction is applied on EVERY time successful synchronization with a time server. This immediately corrects the system time to match server time.
2. Slew rate is calculated ONCE (on the second successful time synchronization with server) and applied henceforth, on every time polling interval period to compensate gradually for the system clock drift during the period.
This PR makes the following changes in the coreSNTP demo:
To suggest the most secure way of using SNTP communication, we are adding a documentation note about the Network Time Security in the SNTP demo.
Hygiene update of using the FreeRTOS/backoffAlgorithm utility library for calculating time polling period interval backoff when time requests are rejected by a time server.
Issue
There is a possible vulnerability of Denial of Service attack by keeping the UDP socket for the SNTP client task always open in the coreSNTP demo. The Denial of Service attack can occur from receiving multiple server response (duplicated or malicious) for a single SNTP time request sent by the client, and thereby, filing the socket network buffer response packets that affect future time requests.
Solution
This PR fixes this vulnerability by updating the demo to keep a UDP socket open only for the time period of waiting for server response, closing the socket on either receiving a server response or experiencing server timeout, and re-creating a UDP socket for the next polling try. This PR also adds another security functionality using a random port for UDP socket to protect against spoofing attacks from "off-network path" attackers.
Update the coreSNTP submodule to the latest commit. Also, make updates to the coreSNTP demo for the new changes in the SNTP library which include the following:
1. Update to the type for packet size from size_t to uint16_t for parameters in the transport and authentication interfaces.
2. Change in the call to Sntp_SendTimeRequest API to pass the new blockTimeMs parameter added to the API.
3. Update to the clock-offfset type from int32_t to int64_t for representing information in milliseconds. To accommodate this update in the SntpSetTime_t interface, the mathematical model for representing system clock has been updated to store slew rate as milliseconds/second (instead of second/second). This change improves the accuracy of the WinSim demo time correction (because the milliseconds of time difference between server and client time is corrected over the entire polling interval which makes a significant difference!).
This PR also adds demo config macros for setting the block time values passed to the Sntp_SendTimeRequest and Sntp_ReceiveTimeResponse APIs.
Update the coreSNTP demo to showcase use of symmetric key algorithm of authentication scheme for securing SNTP communication between client and server.
The demo uses the AES-128-CMAC algorithm for the generating Message Authentication Code for the client on sending the SNTP time request to server as well as validating the server response received by verifying if the payload present authentication code can be generated. Use of an authentication mechanism in SNTP communication protects against server spoofing attacks as well as man-in-the-middle attacks of server response modification.
The demo uses corePKCS11 library for the AES-CMAC operations. Also, the demo adds functionality of generating random number, using corePKCS11, for sending as a parameter to the Sntp_SendTimeRequest API.
Note: For symmetric key based security mechanism to be protective against malicious, it is IMPORTANT to securely pre-share the symmetric key between client and server.
Add the FreeRTOS/coreSNTP library as a submodule (along with manifest.yaml file update) and add a demo project to showcase use of the coreSNTP library for having a SNTP client daemon in the system for periodically synchronizing system time with the internet to maintain Coordinated Univeral Time (UTC) in a device. This demo maintains UTC time of system in RAM, thereby, representing systems without a Real-Time Clock (RTC) module in the device.
Note: This demo shows use of coreSNTP library for SNTP communication with NTP/SNTP time servers in non-authenticated mode (i.e. without any security mechanism payload beyond the standard 48 bytes of NTP packet exchange between client-server).

FreeRTOS_send adds the packet to be sent to the IP task's queue for
later processing. The packet is sent later by the IP task. When
FreeRTOS is used in collaborative mode (i.e. configUSE_PREEMPTION is 0),
the Plaintext_FreeRTOS_send function returns without actually sending
the packet as the IP task never gets a chance to run.
The fact that Plaintext_FreeRTOS_send returns without actually sending
the packet causes an issue in the MQTT_Connect which expects the CONNECT
packet to be actually sent and waits for CONNACK.
This commit adds a taskYIELD call after calling FreeRTOS_send to ensure
that the IP task gets a chance to run and send the packet before the
Plaintext_FreeRTOS_send function returns.
Add URL file links to the MQTT agent documentation page.
Add comment blocks into each demo that also point toward the MQTT agent documentation to ensure users are aware the agent method exists.

From the FreeRTOS documentation, pdFREERTOS_ERRNO_ENOSPC means that timeout occurred before any data could be sent or received.
- In the plaintext transport-interface implementation, we would directly return `-pdFREERTOS_ERRNO_ENOSPC`. However, an error like this can occur when the TCP buffer is full, so this ought to be retriable. Libraries that consume the transport interface interpret a return value of 0 to mean that send/recv can be invoked again to get the data. As such, we should appropriately set the return value as 0 when the status is `-pdFREERTOS_ERRNO_ENOSPC`.
- In the mbedTLS port, we would directly return whatever `FreeRTOS_send` or `FreeRTOS_recv` returns. However, sometimes, the return value can be an error. In such cases, we ought to map an error from FreeRTOS+TCP to an equivalent error in mbedTLS. In the case of `-pdFREERTOS_ERRNO_ENOSPC`, we map that to `MBEDTLS_ERR_SSL_TIMEOUT`. When the mbedTLS transport-interface send/recv wrapper sees that value, it appropriately returns 0, so that the library can retry the send/recv. I've verified that when the mbedTLS port returns an error, that same error is returned by `mbedtls_ssl_write` & `mbedtls_ssl_read`.
- The TCP socket may have a receive block time. If bytesToRecv is greater than 1 then a frame is likely already part way through reception and blocking to wait for the desired number of bytes to be available is the
most efficient thing to do. If bytesToRecv is 1 then this may be a speculative call to read to find the start of a new frame, in which case blocking is not desirable as it could block an entire protocol agent task for the duration of the read block time and therefore negatively impact performance. So if bytesToRecv is 1 then don't call recv unless it is known that bytes are already available.

The MQTT library has been updated with the MQTT_RECV_POLLING_TIMEOUT_MS and MQTT_SEND_RETRY_TIMEOUT_MS configurations which should be set to zero when using a dummy timer function to avoid possibility of infinite loop when retrying failed transport send/receive calls. As the MQTT Keep Alive demo uses a dummy timer function, this PR updates the demo configuration to set these timeouts to zero.
The FreeRTOS+TCP submodule pointer was set to a commit not in main,
which also lacked commits in main, which ended up causing build failures
for defender demo.
Adding demo to demonstrate the use of pre-signed URLs to connect and download from a S3 bucket. Sends multiple GET requests synchronously to download a file in chunks using range headers. Uses a request and response task in addition to the main HTTP servicing task.

By removing the definition of the NetworkContext struct in the header file, we allow the application to define it. This allows an application writer to use multiple transports in the same compilation unit. That way, multiple .c files do not have to be created for each transport.
The API of FreeRTOS/backoffAlgorithm library has changed to remove dependency on random number generator; instead require the caller to generate the random number and pass it to the BackoffAlgorithm_GetNextBackoff API for backoff period calculation. This PR updates the submodule pointer commit, and updates the demos and tests to use the simplied library API
