[PATCHv2 00/25] Reroll of sb/diff-color-moved.

v2:

* on top of the new hashmap patches[3]. It compiles when put on older versions
  of the hashmap series, as the hashmap compare function just swapped void pointers
  in the definition.
  
* better documentation, Thanks Simon!
  ... If there
      are fewer than 3 adjacent moved lines, they are not marked up
      as moved, but the regular colors 'color.diff.{old,new}' will be
      used. ...
      
* clarified the compare function (casting the return to unsigned char, such
  that 0-255 is from the string, -1 indicated EOF. Adapted the checks for that.
  
Thanks,
Stefan

v1:

Reroll of sb/diff-color-moved, applies on top of the hashmap patches[1].

* Supports different whitespace modes correctly now (and has a test for trivial
  white space changes)
* The fixups[2] have been squashed.

Thanks, Stefan
