Angus Gratton 0f5cae0218 heap: Change test_multi_heap_on_host multi-config to bash script not Makefile 
Hopefully fix some CI building issues with parallel builds.

Deomid Ryabkov 712bd1d773 Try to merge tail with next block when splitting 
When splitting a memory block, check if the next block is free.
If it is, then just extend it upwards instead of creating a new block.
This fixes a bug where when shrinking existing allocations would result in irreversible free space fragmentation.

When testing on the host, test all the poisoning configurations.

Angus Gratton f7eecfcc67 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:

cleaner.

heap: Fix race condition causing malloc() to fail under some conditions

Angus Gratton 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).

Angus Gratton 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.

Angus Gratton 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
then re-triggers this check.

Angus Gratton 76d8190444 multi_heap: Print the problem address when aborting due to heap corruption 
New multi_heap code has proven effective at aborting when buffer overruns occur,
but it's currently hard to debug the stack traces from these failures.
