We do not have a backend-agnostic way to write objects into an object
database. While there is `write_object_file()`, this function is rather
specific to the loose object format.
Introduce `odb_write_object()` to plug this gap. For now, this function
is a simple wrapper around `write_object_file()` and doesn't even use
the passed-in object database yet. This will change in subsequent
commits, where `write_object_file()` is converted so that it works on
top of an `odb_source`. `odb_write_object()` will then become
responsible for deciding which source an object shall be written to.

When a repository is configured to have a compatibility hash algorithm
we keep track of object ID mappings for loose objects via the loose
object map. This map simply maps an object ID of the actual hash to the
object ID of the compatibility hash. This loose object map is an
inherent property of the loose files backend and thus of one specific
object source.
Refactor the interfaces to reflect this by requiring a `struct
odb_source` as input instead of a repository. This prepares for
subsequent commits where we will refactor writing of loose objects to
work on a `struct odb_source`, as well.

We implicitly depend on `the_repository` when moving an object file into
place in `finalize_object_file()`. Get rid of this global dependency by
passing in a repository.
Note that one might be pressed to inject an object database instead of a
repository. But the function doesn't really care about the ODB at all.
All it does is to move a file into place while checking whether there is
any collision. As such, the functionality it provides is independent of
the object database and only needs the repository as parameter so that
it can adjust permissions of the file we are about to finalize.

We implicitly depend on `the_repository` in `has_loose_object()`.
Refactor the function to accept an `odb_source` as input that should be
checked for such a loose object.
This refactoring changes semantics of the function to not check the
whole object database for such a loose object anymore, but instead we
now only check that single source. Existing callers thus need to loop
through all sources manually now.
While this change may seem illogical at first, whether or not an object
exists in a specific format should be answered by the source using that
format. As such, we can eventually convert this into a generic function
`odb_source_has_object()` that simply checks whether a given object
exists in an object source. And as we will know about the format that
any given source uses it allows us to derive whether the object exists
in a given format.
This change also makes `has_loose_object_nonlocal()` obsolete. The only
caller of this function is adapted so that it skips the primary object
source.

There are a couple of users of the `the_hash_algo` macro, which
implicitly depends on `the_repository`. Adapt these callers to not do so
anymore, either by deriving it from already-available context or by
using `the_repository->hash_algo`. The latter variant doesn't yet help
to remove the global dependency, but such users will be adapted in the
following commits to not use `the_repository` anymore.

When preparing the latest round of security fixes, we wrote release
notes in v2.43.7, and then successively merged those up through to the
various 'maint' branches.
However, the 2.49 release series is the first to have commit 1f010d6bdf
(doc: use .adoc extension for AsciiDoc files, 2025-01-20). This means
that we should have renamed the new-but-historical release notes from
*.txt to *.adoc during the merge into the 'maint-2.49' branch, but
neglected to do so.
Rename them accordingly to match the convention introduced by
1f010d6bdf. Since the release materials in question here were prepared
before v2.50.0 was tagged, the 'maint' track for that release series is
OK as is.

describe very well what this function actually does, which is to walk

should be way more descriptive.

The "--recursive" flag for git-grep(1) allows users to grep for a string
across submodule boundaries. To make this work we add each submodule's
object sources to our own object database so that the objects can be
accessed directly.
The infrastructure for this depends on a global string list of submodule
paths. The caller is expected to call `add_submodule_odb_by_path()` for
each source and the object database will then eventually register all
submodule sources via `do_oid_object_info_extended()` in case it isn't
able to look up a specific object.
This reliance on global state is of course suboptimal with regards to
our libification efforts.
Refactor the logic so that the list of submodule sources is instead
tracked in the object database itself. This allows us to lose the
condition of `r == the_repository` before registering submodule sources
as we only ever add submodule sources to `the_repository` anyway. As
such, behaviour before and after this refactoring should always be the
same.

In subsequent commits we'll get rid of our use of `the_repository` in

a `struct odb_source`. In some cases though we'll need access to the
repository, for example to read a config value from it, but we don't
have a way to access the repository owning a specific object database.
Introduce parent pointers for `struct object_database` to its owning
repository as well as for `struct odb_source` to its owning object
database, which will allow us to adapt those use cases.
Note that this change requires us to pass through the object database to
`link_alt_odb_entry()` so that we can set up the parent pointers for any
source there. The callchain is adapted to pass through the object
database accordingly.
