### New Features
- git_pack::Find::try_find_cached(…, pack_cache)
With this method it's easier to bypass local caches and control
the cache oneself entirely.
- add linked::Store::rc_iter()
For completeness in case of single-threaded operations
- linked::Store sorts bundles by modification date, newest first
- A simplified version of the `Find` trait
It's meant for the next generation of object db handles which keep a
local cache of all the details of the actual object database.
### Bug Fixes
- support Rust 1.52
- linked::Store now assures unique IDs across compound stores
### Changed (BREAKING)
- cleanup and unify `verify_integrity()` method signature
Previously they used many different ways of handling their parameters
despite all boiling down to calling the same 'index::File::traverse()`
method.
This allows for more reuse of `Options` structs and generally makes
clearer how these optinos are used.
- Change accessors named `hash_kind()` to `object_hash()` for consistency
- consistently use `object_hash` instead of `hash_kind`
- remove `Write::*(…, hash_kind)`
The `hash_kind` is now intrinsic to the implementation of the write
trait and thus isn't passed along anymore in parameters.
The `sink()` function now takes the kind of hash as parameter.
- various changes to the `loose::Store`.
Change `path` field to read-only `path()` method
add `hash_kind` parameter to `loose::Store::at(…, hash_kind)`
- move `sink::Sink` to the top-level exclusively
- move `loose::iter::Iter` to `loose::Iter`
- remove `make_object_cache` parameter from `git_pack::data::output::count::objects()`
It now is an implementation detail of the Find trait.
- Rename `Handle` to `Cache`
Because this is exactly what it is effectively.
Also add some basic instantiation for the new object store.
- remove pack-cache from `Find::try_find(…)`
With the new architecture this can be an implementation detail without
forcing it to be Sync.
- move git_pack::data::Object to git_object::Data, massively alter git_odb::Find trait
This will break a lot, but has to happen to prepare these traits for the
next generation of object databases.
### New Features (BREAKING)
- `Cache::inner` removed in favor of `Deref/Mut` and `into_inner()`
Making the `inner` field available allows changing it, which would make
it potentially incompatible with existing caches. The new
implementation makes it essentially read-only while allowing more
convenient access to methods on `inner`.
