>
> Get task statistics for all tasks with less memory use, by doing it one task at …a time.
> Provide a public iterator over all tasks for diagnostics.
> 
> @aggarg - This is a better refactoring and does not increase stack space use (from #1424):
> \- The public iterator function is cleaner (passes task handle and state plus context to callback).
> \- Does not replicate task location code as in your suggested patch.
> \- Based on the latest development head for easier merge.
> \- Retested in my application.
> 
> Hope you approve!

> Description
> \-----------
> Add uxTaskCallForEachTask, which is the iteration portion of last released uxTaskGetSystemState. uxTaskCallForEachTask calls a user-provided callback once for each task (with the task handle and state, plus a context).
> 
> Refactor uxTaskGetSystemState so that it uses uxTaskCallForEachTask to fill in the pre-allocated array of TaskStatus\_t, preserving the existing uxTaskGetSystemState API for current users.
> 
> Test Steps
> \-----------
> 1. Use uxTaskCallForEachTask to observe task statistics for each task in the system.
> 2. Compare existing uxTaskGetSystemState output to new version.
> 
> Checklist:
> \----------
> \- \[x \] I have tested my changes. No regression in existing tests.
> \- \[\] I have modified and/or added unit-tests to cover the code changes in this Pull Request.
