Log Message:
Update libgit2 to 0.24.0.

v0.24
-------

### Changes or improvements

* Custom filters can now be registered with wildcard attributes, for
  example `filter=*`.  Consumers should examine the attributes parameter
  of the `check` function for details.

* Symlinks are now followed when locking a file, which can be
  necessary when multiple worktrees share a base repository.

* You can now set your own user-agent to be sent for HTTP requests by
  using the `GIT_OPT_SET_USER_AGENT` with `git_libgit2_opts()`.

* You can set custom HTTP header fields to be sent along with requests
  by passing them in the fetch and push options.

* Tree objects are now assumed to be sorted. If a tree is not
  correctly formed, it will give bad results. This is the git approach
  and cuts a significant amount of time when reading the trees.

* Filter registration is now protected against concurrent
  registration.

* Filenames which are not valid on Windows in an index no longer cause
  to fail to parse it on that OS.

* Rebases can now be performed purely in-memory, without touching the
  repository's workdir.

* When adding objects to the index, or when creating new tree or commit
  objects, the inputs are validated to ensure that the dependent objects
  exist and are of the correct type.  This object validation can be
  disabled with the GIT_OPT_ENABLE_STRICT_OBJECT_CREATION option.

* The WinHTTP transport's handling of bad credentials now behaves like
  the others, asking for credentials again.

### API additions

* `git_config_lock()` has been added, which allow for
  transactional/atomic complex updates to the configuration, removing
  the opportunity for concurrent operations and not committing any
  changes until the unlock.

* `git_diff_options` added a new callback `progress_cb` to report on the
  progress of the diff as files are being compared. The documentation of
  the existing callback `notify_cb` was updated to reflect that it only
  gets called when new deltas are added to the diff.

* `git_fetch_options` and `git_push_options` have gained a `custom_headers`
  field to set the extra HTTP header fields to send.

* `git_stream_register_tls()` lets you register a callback to be used
  as the constructor for a TLS stream instead of the libgit2 built-in
  one.

* `git_commit_header_field()` allows you to look up a specific header
  field in a commit.

* `git_commit_extract_signature()` extracts the signature from a
  commit and gives you both the signature and the signed data so you
  can verify it.

### API removals

* No APIs were removed in this version.

### Breaking API changes

* The `git_merge_tree_flag_t` is now `git_merge_flag_t`.  Subsequently,
  its members are no longer prefixed with `GIT_MERGE_TREE_FLAG` but are
  now prefixed with `GIT_MERGE_FLAG`, and the `tree_flags` field of the
  `git_merge_options` structure is now named `flags`.

* The `git_merge_file_flags_t` enum is now `git_merge_file_flag_t` for
  consistency with other enum type names.

* `git_cert` descendent types now have a proper `parent` member

* It is the responsibility of the refdb backend to decide what to do
  with the reflog on ref deletion. The file-based backend must delete
  it, a database-backed one may wish to archive it.

* `git_config_backend` has gained two entries. `lock` and `unlock`
  with which to implement the transactional/atomic semantics for the
  configuration backend.

* `git_index_add` and `git_index_conflict_add()` will now use the case
  as provided by the caller on case insensitive systems.  Previous
  versions would keep the case as it existed in the index.  This does
  not affect the higher-level `git_index_add_bypath` or
  `git_index_add_frombuffer` functions.

* The `notify_payload` field of `git_diff_options` was renamed to `payload`
  to reflect that it's also the payload for the new progress callback.

* The `git_config_level_t` enum has gained a higher-priority value
  `GIT_CONFIG_LEVEL_PROGRAMDATA` which represent a rough Windows equivalent
  to the system level configuration.

* `git_rebase_init()` not also takes a merge options.

* The index no longer performs locking itself. This is not something
  users of the library should have been relying on as it's not part of
  the concurrency guarantees.
