Associate secure context with task handle
The secure side context management code now checks that the secure

Pre-allocate secure-side context structures
This commit improves ARMv8-M security by pre-allocating secure-side task
context structures and changing how tasks reference a secure-side
context structure when calling a secure function. The new configuration
constant secureconfigMAX_SECURE_CONTEXTS sets the number of secure
context structures to pre-allocate. secureconfigMAX_SECURE_CONTEXTS
defaults to 8 if left undefined.

Make the type used to hold run-time counter values configurable (#350)
* Introduce configRUN_TIME_COUNTER_TYPE which enables developers to define the type used to hold run time statistic counters. Defaults to uint32_t for backward compatibility. #define configRUN_TIME_COUNTER_TYPE to a type (for example, uint64_t) in FreeRTOSConfig.h to override the default.
Introduce ulTaskGetIdleRunTimePercent() to complement the pre-existing ulTaskGetIdleRunTimeCounter(). Whereas the pre-existing function returns the raw run time counter value, the new function returns the percentage of the entire run time consumed by the idle task. Note the amount of idle time is only a good measure of the slack time in a system if there are no other tasks executing at the idle priority, tickless
idle is not used, and configIDLE_SHOULD_YIELD is set to 0.

Remove support for tmrCOMMAND_START_DONT_TRACE (#305)
* Remove support for tmrCOMMAND_START_DONT_TRACE
Prior to this commit, the timer task used tmrCOMMAND_START_DONT_TRACE
to reload a "backlogged" auto-reload timer -- one for which a reload
operation would have started a period that had already elapsed. If the
command queue contained a stop or delete command when
tmrCOMMAND_START_DONT_TRACE was put into the queue for a reload, the
timer unexpectedly restarted when the timer task processed
tmrCOMMAND_START_DONT_TRACE. This commit implements a new method of
reloading auto-reload timers and eliminates support for
tmrCOMMAND_START_DONT_TRACE. No other code sends this private command.
However, the symbol tmrCOMMAND_START_DONT_TRACE remains defined, with
its original command value, so as not to impact trace applications.
Also fix one-shot timers that were not reliably being marked as not
active:
- when they expired before the start command could be processed
- when the expiration was processed during the timer list switch
Also improve consistency:
- Always reload auto-reload timers *before* calling the callback.
- Always call traceTIMER_EXPIRED() just prior to the callback.
* fix indent
* Revert unnecessary change to prvTimerTask()
Change was intended to faithfully work through a backlog that spanned a
list switch, and before processing a stop or delete command. But, (1)
it isn't important to do that, and (2) the code didn't accomplish the
intention when *two* auto-reload timers were backlogged across a list
switch. Best to simply leave this part of the code as it was before.
* fix style

Support allocating stack from separate heap (#267)
The change adds support for allocating task stacks from separate heap.
When configSTACK_ALLOCATION_FROM_SEPARATE_HEAP is defined as 1 in
FreeRTOSConfig.h, task stacks are allocated and freed using
pvPortMallocStack and vPortFreeStack functions. This allows the
application writer to provide a separate allocator for task stacks.

stacks are allocated and freed using FreeRTOS heap functions
pvPortMalloc and vPortFree.
For backward compatibility, configSTACK_ALLOCATION_FROM_SEPARATE_HEAP
defaults to 0.
