A few changes:
- removed an unnecessary VG_(unmap_range)() call in do_brk() -- the
  VG_(munmap)() just before it does it anyway.
- inlined mprotect_segment() and munmap_segment() because it's more concise and
  easier to understand that way.
- a couple of minor formatting changes
- added and cleaned up a couple of comments
