Merge branch 'en/merge-directory-renames'

Browse Source 
"git merge-recursive" backend recently learned a new heuristics to
infer file movement based on how other files in the same directory
moved.  As this is inherently less robust heuristics than the one
based on the content similarity of the file itself (rather than
based on what its neighbours are doing), it sometimes gives an
outcome unexpected by the end users.  This has been toned down to
leave the renamed paths in higher/conflicted stages in the index so
that the user can examine and confirm the result.

* en/merge-directory-renames:
  merge-recursive: switch directory rename detection default
  merge-recursive: give callers of handle_content_merge() access to contents
  merge-recursive: track information associated with directory renames
  t6043: fix copied test description to match its purpose
  merge-recursive: switch from (oid,mode) pairs to a diff_filespec
  merge-recursive: cleanup handle_rename_* function signatures
  merge-recursive: track branch where rename occurred in rename struct
  merge-recursive: remove ren[12]_other fields from rename_conflict_info
  merge-recursive: shrink rename_conflict_info
  merge-recursive: move some struct declarations together
  merge-recursive: use 'ci' for rename_conflict_info variable name
  merge-recursive: rename locals 'o' and 'a' to 'obuf' and 'abuf'
  merge-recursive: rename diff_filespec 'one' to 'o'
  merge-recursive: rename merge_options argument from 'o' to 'opt'
  Use 'unsigned short' for mode, like diff_filespec does

Whether and how Git detects renames. If set to "false",
rename detection is disabled. If set to "true", basic rename

merge.directoryRenames::
Whether Git detects directory renames, affecting what happens at
merge time to new files added to a directory on one side of
history when that directory was renamed on the other side of
history. If merge.directoryRenames is set to "false", directory
rename detection is disabled, meaning that such new files will be
left behind in the old directory. If set to "true", directory
rename detection is enabled, meaning that such new files will be
moved into the new directory. If set to "conflict", a conflict
will be reported for such paths. If merge.renames is false,
merge.directoryRenames is ignored and treated as false. Defaults
to "conflict".
