b7fc067c8c heap: Fix bug when realloc moves data between heaps 
When realloc-ing to a smaller buffer size which ends up allocated in a different heap, the heap
structure is corrupted. This can only happen:

* If heap checking is Comprehensive (meaning buffers are never shrunk in place) and the heap the buffer was originally allocated in is full.
* Calling heap_caps_realloc() to deliberately move a buffer to a different capabilities type, and shrink it at the same time.

Probable fix for https://github.com/espressif/esp-idf/issues/1582
Probably the same issue:

a376475c2b Add esp_heap_debug_dump_totals() to monitor heap usage 
esp_heap_debug_dump_totals() dumps into a user-provided data structure
a summary of the amound of heap memory in region type that is used by
each task.  Optionally it will also dump into another data structure
the metadata about each allocated block for a given list of tasks or
for all tasks (limited by available space).

bc56804a49 Add task tracking option for heap usage monitoring 
Add back a feature that was available in the old heap implementation
in release/v2.1 and earlier: keep track of which task allocates each
block from the heap. The task handle is conditionally added as
another word in the heap poisoning header under this configuration
option CONFIG_HEAP_TASK_TRACKING.

To allow custom monitoring and debugging code to be added, add helper
functions in multi_heap.c and multi_heap_poisoning.c to provide access
to information in the block headers.

b0c5665f15 heap: Fix race condition causing malloc() to fail under some conditions 
During a call to multi_heap_malloc(), if both these conditions were true:
- That heap only has one block large enough for the allocation
  (this is always the case if the heap is unfragmented).
- Another allocation is simultaneously occurring in the same heap.

... multi_heap_malloc() could incorrectly return NULL.

This caused IDF heap_caps_malloc() and malloc() to also fail, particularly
often if only one or two heaps had space for the allocation (otherwise
heap_caps_malloc() fails over to the next heap).

04188d8ec7 heap: Fix spurious heap_caps_check_integrity() errors in Comprehensive mode 
Heap was not being locked before poisoning, so heap_caps_check_integrity()
would sometimes race with checking the poison bytes and print unnecessary
errors.

959462ffb6 multi_heap_poisoning: Use MULTI_HEAP_STDERR_PRINTF (ets_printf) to print heap errors 
Needed because normal printf() can trigger a malloc() (for standard stream locks) which
