* memory managment calls now forwarded to freertos heap * memory managment tests * local target test compability * rename heap.c file to heap_4.c for local target and explicity init heap in single thread context * rebase BlockLink_t struct * check mutex in local heap Co-authored-by: aanper <mail@s3f.ru>
