bc2879a956 heap: 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.

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).

Address change requests on PR #1498

This set of changes fixes the files in e3b702c to just add the
CONFIG_HEAP_TASK_TRACKING option without adding the new function
heap_caps_get_per_task_info() in case that is the only portion of the
PR that will be accepted.  Part of the change is to remove the new .c
and .h files containing that function and to remove the line to
compile it from components/heap/component.mk since it should not have
been included in e3b702c.  One or more additional commits to add the
new function will follow.

The other changes here:
- uint32_t get_all_caps() moves to heap_private.h
- replace "void* foo" with "void *foo"
- add braces around single-line "if" blocks
- replace tab characters with spaces

Address change requests on PR #1498, part 2

This set of changes fixes the files in cdf32aa to add the new function
heap_caps_get_per_task_info() with its new name and to add the line to
compile it in components/heap/component.mk.  This does not address all
the suggested changes because there are some needing further
discussion.

This commit does not include the suggested change to move the
declaration of the new function into esp_heap_caps.h because the new
function references TaskHandle_t so esp_heap_caps.h would have to
include freertos/FreeRTOS.h and freertos/task.h, but FreeRTOS.h
includes esp_heap_caps.h through two other header files which results
in compilation errors because not all of FreeRTOS.h has been read yet.

Change heap_caps_get_per_task_info() to take struct of params

In addition to moving the large number of function parameters into a
struct as the single parameter, the following changes were made:

- Clear out the totals for any prepopulated tasks so the app code
  doesn't have to do it.

- Rather than partitioning the per-task totals into a predetermined
  set of heap capabilities, take a list of <caps,mask> pairs to
  compare the caps to the heap capabilities as masked.  This lets the
  caller configure the desired partitioning, or none.

- Allow the totals array pointer or the blocks array pointer to be
  NULL to indicate not to collect that part of the information.

- In addition to returning the total space allocated by each task,
  return the number of blocks allocated by each task.

- Don't need to return the heap capabilities as part of the details
  for each block since the heap region (and therefore its
  capabilities) can be determined from the block address.

- Renamed heap_task_info.h to esp_heap_task_info.h to fit the naming
  convention, and renamed the structs for totals and block details to
  better fit the revised function name.

- Provide full Doxygen commenting for the function and parameter
  structs.
