New Features

• add objects::tree::diff::Platform::stats() to quickly obtain diff-stats.
  This function is inspired by git2 which also makes it very simple to obtain.
• allow threaded-handling of tree-diff changes.
  This works by providing Change::detach() and ChangeDetached::attach().
• add Reference::follow_to_object()
  It's an equivalent to git2::Reference::resolve().`
• add Repository::diff_resource_cache_for_tree_diff()
• add Reference::peel_to_kind()
  Make it easy to follow a ref and peel it to a given object type.
  Additional peel_to_<kind>() shortcuts are also provided, with
  the same name as in git2.
• add Repository::find_*() methods for every object type.
• add Repository::compute_object_cache_size_for_tree_diffs().
  With it it's easier to obtain reasonable object cache sizes as optimized
  for tree-diffs.
• remote::Name::to_owned() to get a static version of it.
  Also, add optional serde support.
• Reference::remote_name() now also provides valid remote names for local tracking branches.
• add Reference::peel_to_id_in_place_packed() to allow passing a packed-buffer snapshot.
  This is useful for speeding up reference lookups as otherwise, it will have to validate the packed-buffer
  snapshot didn't change internally each time a ref is peeled.
• add remote::Names as shortcut to the value returned for all remote names.

Bug Fixes

• similarity detection
  Previously it would incorrectly count only the last batch of removed bytes, and now it will count all of them. This leads to realistic results with complex diffs, even though it's probably still not en-par with Git which uses more complex heuristics.

• prevent panic in Repository::rev_parse_single() when HEAD was invalid.
  When using a refspec like HEAD:file.

• do not automatically use a parallel directory walk.
  This reduces dependencies and can speed-up typical ref-walks as these
  don't benefit from this many threads - the overhead here usually outweighs
  the benefit.

  This can be turned back on based on the expected workload.

Other

• make tree-diff more easily discoverable when coming from git2

Bug Fixes (BREAKING)

• better peeling performance for reference traversal.
  This is done by keeping a packed-buffer around and reusing it, instead
  of re-checking it every time.

  For this to work, the peeled() function on the reference::Iter can now fail
  as it has to open a packed-refs snapshot.
