{
  Fills 'struct FreeBlocksData' structure, with each struct MemEntry
  representing single free block. Normally all free blocks in all memory
  headers are scanned, but SYSTEMINFOTAG_MEMHEADER can be used to limit
  the scanning to a single memory header. If successfull,
  NewGetSystemAttrs return TRUE, and then fbd_NumBlocks contains the
  number of struct MemEntry entries filled.

  You can also use SYSTEMINFOTAG_HOOK to have your custom hook called
  rather than having array being filled. The hook is called within
  Forbid() and the forbid must NOT be broken. The hook is called with:
   A0 - PHook
   A1 - PMemEntry
   A2 - PMemHeader
  The hook must return success/failure indicator, returning FALSE causes
  the NewGetSystemAttrs call to abort instantly and return FALSE.
