Speeding up procedure for getting start of a heap block's data space for one-chunked blocks, removing general blocks support from the procedure.

Browse Source 
- heap area is aligned on heap chunk size;
 - mem_heap_get_block_start is renamed to mem_heap_get_chunked_block_start,
   now this interface is applicable only to one-chunked blocks,
   and is significantly faster - instead of iterating list of heap blocks
   to find block header, it just aligns value of pointer to heap chunk size.
