  exec/memory: Extract address_space_set() from dma_memory_set()

dma_memory_set() does a DMA barrier, set the address space with
a constant value. The constant value filling code is not specific
to DMA and can be used for AddressSpace. Extract it as a new
helper: address_space_set().

  Log Message:

  hw/elf_ops: clear uninitialized segment space

When the mem_size of the segment is bigger than the file_size,
and if this space doesn't overlap another segment, it needs
to be cleared.

This bug is very similar to the one we had for linux-user,
22d113b52f41 ("linux-user: Fix loading of BSS segments"),
where .bss section is encoded as an extension of the the data
one by setting the segment p_memsz > p_filesz.
