Merge branch 'en/merge-recursive-cleanup'

Browse Source 
The merge-recursive machiery is one of the most complex parts of
the system that accumulated cruft over time.  This large series
cleans up the implementation quite a bit.

* en/merge-recursive-cleanup: (26 commits)
  merge-recursive: fix the fix to the diff3 common ancestor label
  merge-recursive: fix the diff3 common ancestor label for virtual commits
  merge-recursive: alphabetize include list
  merge-recursive: add sanity checks for relevant merge_options
  merge-recursive: rename MERGE_RECURSIVE_* to MERGE_VARIANT_*
  merge-recursive: split internal fields into a separate struct
  merge-recursive: avoid losing output and leaking memory holding that output
  merge-recursive: comment and reorder the merge_options fields
  merge-recursive: consolidate unnecessary fields in merge_options
  merge-recursive: move some definitions around to clean up the header
  merge-recursive: rename merge_options argument to opt in header
  merge-recursive: rename 'mrtree' to 'result_tree', for clarity
  merge-recursive: use common name for ancestors/common/base_list
  merge-recursive: fix some overly long lines
  cache-tree: share code between functions writing an index as a tree
  merge-recursive: don't force external callers to do our logging
  merge-recursive: remove useless parameter in merge_trees()
  merge-recursive: exit early if index != head
  Ensure index matches head before invoking merge machinery, round N
  merge-recursive: remove another implicit dependency on the_repository
