The GIT_WORK_TREE variable prepared to invoke the push-to-checkout

This is now a description list (see previous commit) and parentheticals
like this do not go on the left-hand side. Moving it to the other side
makes it stand out just as much and is also more consistent with the
rest of the documentation.
Let’s also do the same for the `replay.refAction` description list.
That makes the two desc. lists identical in the first sentence. Let’s
add a comment about that for future editors.

This bullet list for `--ref-action` introduces a term with a colon.
This is exactly what a description list is, structurally. Let’s be
sylistically consistent and use the desc. list markup construct.[1]
We can reuse the `::` delimiter since we use an open block.
But for consistency use the typical nested description list
delimiter, namely `;;`.
Also drop the harmless but unneeded indentation.

Inside the function `fetch_and_setup_pack_index()`, when the pack
obtained using `parse_pack_index()` fails to be verified by
`verify_pack_index()`, the function returns without closing and freeing
said pack.
Fix this by calling `close_pack_index()` to munmap the index file for
the leaking pack (which might have been mmapped by `fetch_pack_index()`
or `verify_pack_index()`), and then free it, when the verification
fails.

Now that all callbacks of the loose source operate on `struct
odb_source_loose` directly we no longer have to reach into the "files"
source at all.
Drop this field and update `odb_source_loose_new()` to instead accept
all parameters required to initialize itself. This ensures that the

Stub out remaining callback functions for the "loose" backend.
Note that we also stub out transactions for loose objects. In fact, we
already have the infrastructure in place for those, and we could in
theory implement those, as well. But there are separate efforts ongoing
to polish up transactional interfaces, and doing so now would likely
result in some messiness. This omission will thus be worked on in a
subsequent patch series, once the dust has settled.

Wire up the `write_object_stream()` callback.
Note that we don't move the implementation into "odb/source-loose.c".
This is because most of the logic to write loose objects is still
contained in "object-file.c", and detangling that requires us to do some
refactorings as explained in the preceding commit. So for now, the
implementation of writing an object stream is still located in
"object-file.c".

The "object-file" subsystem still hosts the majority of logic used to
write loose objects. Eventually, we'll want to move this logic into
"odb/source-loose.c", but this isn't yet easily possible because a lot
of the writing logic is still being shared with `force_object_loose()`.
We will eventually detangle this logic so that we can indeed move all of
it into the "loose" source. Meanwhile though, refactor the code so that
it operates on a `struct odb_source_loose` directly to already make the
dependency explicit.

Move `odb_source_loose_write_object()` from "object-file.c" into
"odb/source-loose.c" and wire it up as the `write_object()` callback of
the loose source.
As in preceding commits, this requires us to expose a couple of generic
functions from "object-file.c" as they are used in both subsystems now.
Signed-off-by: Patrick Steinhardt <ps@pks.im>
Signed-off-by: Junio C Hamano <gitster@pobox.com>
While the loose object map functions in "loose.c" accept a generic
`struct odb_source *`, they always expect this to be the "files"
backend. Furthermore, the subsystem doesn't even care about the "files"
backend, but only uses it as a stepping stone to get to the "loose"
backend.
This assumption is implicit and thus not immediately obvious. Refactor
the interfaces to instead operate on a `struct odb_source_loose`
instead, which eliminates the implicit dependency and unnecessary detour
via the "files" source.
