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:

Try to allocate some WiFi and LWIP memories in SPIRAM first. If
failed, try to allocate in internal RAM then.

heap: Support adding new heap regions at runtime

To facilitate this, the list of registered heap regions is now a linked list
(allowing entries to be appended at runtime.)

May happen due to sdkconfig, static allocation of RAM.
