Currently in Armv8-M GCC/ArmClang ports, constant pool is used to
define literals needed for `ldr` instructions. However, those
constant pools are defined with `.align 4` which increases code size.
Instead of defining the constant pool with `.align 4`, let the
compiler hanlde the constant pool and the required alignment.

The difference between a stream buffer and a stream batching buffer is when
a task performs read on a non-empty buffer:
- The task reading from a non-empty stream buffer returns immediately
regardless of the amount of data in the buffer.
- The task reading from a non-empty steam batching buffer blocks until the
amount of data in the buffer exceeds the trigger level or the block time
expires.

* 64bit TickType_t is supported on Windows port.(MSVC and MinGW)
Especially it is introduced for 64bit compiler.(x64 platform on MSVC and MinGW-w64)
* Unnecessary compiler warning for the cast operation is disabled locally.(MinGW-w64 only)
* Modify the condition for ignoring compiler warning for the cast operation.
Before modification: Compiler warning was ignored only on MinGW64
After modification: Compiler warning is ignored on MinGW32 and MinGW64
Reason of modification: The cast warning here is unavoidable not only on MinGW64 but also on MinGW32.
"__GNUC__" macro is used because MSVC does not recognize this #pragma directive.
Add a compile time check that emits a helpful error message if the user
attempts to create a daemon task startup hook without also creating the
timer/daemon task.
The timer/daemon task startup hook runs in the context of the timer/daemon
task. Therefore, it won't run even if configUSE_DAEMON_TASK_STARTUP_HOOK
is set to 1 if the timer task isn't created. The timer task is only created if
configUSE_TIMERS is not equal to 0.
* pxIndex should only be used when selecting next task. Altering pxIndex
of a ready list will cause the scheduler to be unable to select the
right task to run. Using a for loop if traversing the list for trace
utility is required.
* Not defining listGET_OWNER_OF_NEXT_ENTRY when using SMP scheduler

* Fix small bugs
* Cast sizeof to BaseType_t
* Test removing assert to fix UT
* Revert change to tasks.c
Since configIDLE_TASK_NAME must be defined as a string according to
the documentation, the macro will always be NULL terminated. Which
means that the check `if( cIdleName[ xIdleTaskNameIndex ] == ( char ) 0x00 )`
will catch the end of string.
* Update coverity config; Add coverity version; Update pvPortMalloc declaration to match the definitions.
* Add port files to sed command
* Remove warnings about unused parameters in port code

* Update task notification scheduler suspension
Previously ulTaskGenericNotifyTake() and xTaskGenericNotifyWait() would suspend
the scheduler while inside a critical section.
This commit changes the order by wrapping the critical sections in a scheduler
suspension block. This logic is more inuitive and allows the SMP scheduler
suspension logic to be simplified.
* tasks.c: Fix typo
* Use a complete sentence in comment
* Check portGET_CRITICAL_NESTING_COUNT when scheduler is running
* Prevent potential NULL pointer access when scheduler is not running
