[PATCH 0/3] convert diff flags to be stored in a struct

There has be some desire to add additional flags to the diff machineery (https://public-inbox.org/git/20171024000931.14814-1-sbeller@google.com/) but due to the limits of the number of bits in an unsigned int on some systems we can't add any additonal flags to the 'flags' variable. This series converts the flags to be stored in bitfields in a struct instead of in bit positions in an unsigned int.

Some thoughts:
 * We may want to do a follow on patch to convert all the flags from being in
   uppercase to lower case.
 * Maybe we can figure out how to remove the 'touched_flags' things (since its
   only used in one place) and then we may even be able to stop needing to use
   macros to set/clr/test the flags.

  add: use DIFF_OPT_SET macro to set a diff flag
  reset: use DIFF_OPT_SET macro to set a diff flag
  diff: convert flags to be stored in bitfields
