Description
-----------
This PR solves the Issue #321.
**Learning:** Unit tests are supposed to be built with asserts enabled
during the development process. But when these are built for coverage
analysis these should be built with asserts disabled. This is because
the lcov tool would consider all the branches in the asserts as
uncovered.
This PR:
1. Update the unit tests to work with asserts enabled
2. Update the code to have 100% branch coverage. To achieve this, one
branch which was logically unreachable, was excluded from the coverage
analysis.
3. Updates the CI checks to build the code with asserts to check if all
the unit tests are working as expected. Along with this it will also
build the code without asserts to check coverage.
4. Updates the command in the README.md that users should use to build
the unit tests. This command has asserts disabled, as asserts are only
required during the development process of the unit tests.
Test Steps
-----------
The unit tests are building and running successfully with asserts. They
also give 100% coverage without asserts.

This PR enables the coreMQTT library to resend unacked publishes on an
unclean session connection.
Following is a brief summary of changes:
1. Add a new API `MQTT_InitRetransmits` that will initialise the context
to handle publish retransmits on an unclean session connection
2. Add signatures of callback function pointers that users will define
in order to:
a. copy and store outgoing publishes
b. retrieve copied publish on an unclean session connection to resend
c. clear a copied publish when a `PUBACK`/`PUBREC` is received
d. clear all copied publishes on a clean session connection
3. Update the API's to check if callback's are defined and implement
resend publishes as required.
Following are the specifics of the changes:
1. Add 3 new MQTTStatus_t values: MQTTPublishStoreFailed,
MQTTPublishRetrieveFailed and MQTTPublishClearAllFailed
2. Update `MQTTContext_t` to hold the callback function pointers
a. `MQTTRetransmitStorePacket storeFunction`
b. `MQTTRetransmitRetrievePacket retrieveFunction`
c. `MQTTRetransmitClearPacket clearFunction`
d. `MQTTRetransmitClearAllPackets clearAllFunction`
3. Update the `MQTT_Status_strerror` function to handle the new
`MQTTStatus_t` values
4. Add a new API function `MQTT_InitRetransmits` that will initialise
the new callback functions in the `MQTTContext_t`
5. Add this API to the core_mqtt.h file to make it available to users
6. Modify `MQTT_Publish`
a. copy the outgoing publish packet in form of an array of
`TransportOutVector_t` if the callback if defined
b. if copy fails then bubble up corresponding error status code
7. Modify `MQTT_ReceiveLoop`
a. on receiving a `PUBACK`/`PUBREC` clear the copy of that particular
publish after the state of the publish record has been successfully
updated, if the callback if defined
8. Modify `MQTT_Connect`
a. on a clean session clear all the copies of publishes stored if the
callback is defined
b. if clear all fails then bubble up corresponding error status code
c. on an unclean session get the packetID of the unacked publishes and
retrieve the copies of those if the callback is defined
d. if retrieve fails then bubble up corresponding error status code
Approaches Taken
---------------
- To let user know about the changes we have made we will add them to a
changelog and have a minor version bump
- To be in line with the zero copy principle in our library we chose to
provide and retrieve the publish packets for storing and resending in
form of an array of `TransportOutVector_t`
- Code is written in a way that on receiving a `PUBACK`/`PUBREC` the
copy will be cleared after the state of the publish record is changed so
that if state update fails the copy won't be cleared. Otherwise if the
state does not change and the copy is cleared then when a connection is
made with an unclean session there will be a retrieve fail as the system
is in an inconsistent state.
- We are storing the copies of the publishes with the Duplicate flag set
this is because on retrieving the packet we will get it in the form of a
`TransportOutVector_t` that holds the data in a `const` pointer which
cannot be changed after retrieving.
Pending Tasks
---------------
- [ ] Changelog
- [ ] Minor version bump
- [x] Doxygen example for the new API

Following is a brief summary of changes:
1. Check the connected flag before doing any send operation on the
connection
2. Make all the APIs that do send operations, thread safe
3. Update the connected flag within MQTT_Disconnect regardless of the
return status of the send operation
Following are the specifics of the changes:
1. Add 3 new MQTTStatus_t values: MQTTStatusConnected,
MQTTStatusNotConnected and MQTTStatusDisconnectPending
2. Added 1 new MQTTConnectionStatus_t value: MQTTDisconnectPending
3. Update the MQTT_Status_strerror function to handle the new
MQTTStatus_t values
4. Add a new API function MQTT_CheckConnectStatus() that will check the
value of the context→connectStatus flag safely.
5. Add this API to the core_mqtt.h file to make it available to users
6. Check the connected flag before doing any Send operation (following
API's are updated)
a. sendPublishAcks
b. MQTT_Connect
c. MQTT_Subscribe
d. MQTT_Publish
e. MQTT_Ping
f. MQTT_Unsubscribe
g. MQTT_Disconnect
7. Use the MQTT_PRE_STATE_UPDATE_HOOK() and
MQTT_POST_STATE_UPDATE_HOOK() to make the send APIs thread safe
8. The connect status is set to MQTTDisconnectPending whenever a
transport send or receive function returns a negative error code
9. `const` keyword for the the MQTTStatus_t is removed in the input
parameters for the receive functions as we need to update the connection
status when the receive function returns a negative error code
Relevant Explanations
---------------
- MQTT_PRE_SEND_HOOK(): The Pre and Post Send hook Macros are not
required now, as the sending logic will be within the pre and post state
update hook itself. (because we cannot allow other threads to change the
connection state of the application until a send operation is complete).
- I have split the handleSessionResumption function. The part of that
function which was handling the clean session has been added within the
mutex calls in the [MQTT_Connect
API](https://github.com/FreeRTOS/coreMQTT/pull/305/files#diff-2534a3c0229ae9af3801f2a5c6a24eeef2cd0a686671f0371a11d2718ba4fdd6R2828)
and the unclean session part is handled by this new function that is
[called outside the mutex
calls](https://github.com/FreeRTOS/coreMQTT/pull/305/files#diff-2534a3c0229ae9af3801f2a5c6a24eeef2cd0a686671f0371a11d2718ba4fdd6R2866).

**Issue1:**
Mocked function calls jump to real implementation instead of mocks on
mac
**Solution:**
Convert the symbols of the mocked implementation from weak to strong
**Issue2:**
lcov generating wrong coverage reports on mac
**Solution:**
Rectifying network buffer size to be of the appropriate value otherwise
memset clears out more memory spaces than required which leads to
reseting the line coverage counters.
**Issue3:**
log statements being taken as branches
**Solution:**
Removing the ternary operation to figure out if there is a '/' in front
of the file name or not. This can be done as this feature is just for
debugging purposes.
**Issue4:**
Some tests failing randomly on mac
**Solution:**
Initialise variables at places where necessary

The loggging defaults were split out since they are not namespaced to
coreMQTT, and they previously leaked to all files including a coreMQTT
header. Splitting them allowed the logging defaults to only be pulled
into coreMQTT source files. Now that no header files use the config
headers, and thus all coreMQTT config only affects coreMQTT source
files, the split is no longer needed.
core_mqtt_serializer.h included the user coreMQTT config, which spills
the config header's contents into all consumers of coreMQTT's headers.
Macros from the config are no longer used in the the API, so this is
also no longer used for anything, so can be removed.

* Use new version of CI-CD Actions, checkout@v3 instead of checkout@v2 on all jobs
* Use cSpell spell check, and use ubuntu-20.04 for formatting check
* Add in bot formatting action
The code for handleKeepAlive() (which is invoked as part of MQTT_ProcessLoop()) does not invoke the STATE_UPDATE_HOOK macros, but still reads from pContext->lastPacketTxTime. Therefore, this causes a RW race condition which is picked up by ThreadAnalyzer. With a sufficiently meddlesome scheduler, the value of lastPacketTxTime could be different for each time it is checked inside of handleKeepAlive() , causing unreliable behavior in the transmission of KeepAlive packets.

The commit adds a stub for memmove accelerate CBMC coverage
calculation. Without this stub, coverage for `MQTT_ProcessLoop` and
`MQTT_ReceiveLoop` fails to converge (gets stuck generating the SAT
formula for the memmove in `receiveSingleIteration`). This stub
checks that src and dst are nonnull pointers and havocs dst.

core_mqtt.h and other coreMQTT headers pull in core_mqtt_config.h and core_mqtt_config_defaults.h.
core_mqtt_config_defaults.h defines empty logging macros. This means every application that uses coreMQTT needs to be careful to set up the logging stack before including core_mqtt.h or they may mysteriously not have logging output.
The logging setup should be in each compilation object, not set up in headers. This moves the inclusion of default logging macros from the headers to the library c files.
This fixes the issue with the logging macros for customers who do not set the logging macros in their core_mqtt_config.h. However, those who do enable logging for coreMQTT will still have their coreMQTT logging setup in all their c files using coreMQTT.

Non-functional change to handle all enum values for MQTTPublishState_t
and MQTTQoS_t in switch statements. This allows users to compile with
-Werror=switch-enum.
