[0/2] migration/xbzrle: make xbzrle_encode_buffer little easier

Current xbzrle_encode_buffer() do everything in a big loop, which is a little
difficult for audience to catch the logic.

We can refine the logic with:

  * get the length of a run
  * encode it

At the same time, I found the encoding and decoding function has some extra
pointer operation. Removing this could save some code space.
