Using "--cover-letter" we can tell format-patch to generate a cover
letter, in this cover letter there's a list of commits included in the
patch series and the format is specified by the "--cover-letter-format"
option. Would be useful if this format could be configured from the
config file instead of always needing to pass it from the command line.
Teach format-patch how to read the format spec for the cover letter from
the config files. The variable it should look for is called
format.commitListFormat.
Possible values:
- commitListFormat is set but no string is passed: it will default to
"[%(count)/%(total)] %s"
- if a string is passed: will use it as a format spec. Note that this
is either "shortlog" or a format spec prefixed by "log:"
e.g."log:%s (%an)"
- if commitListFormat is not set: it will default to the shortlog
format.

Often when sending patch series there's a need to clarify to the
reviewer what's the purpose of said series, since it might be difficult
to understand it from reading the commits messages one by one.
"git format-patch" provides the useful "--cover-letter" flag to declare
if we want it to generate a template for us to use. By default it will
generate a "git shortlog" of the changes, which developers find less
useful than they'd like, mainly because the shortlog groups commits by
author, and gives no obvious chronological order.
Give format-patch the ability to specify an alternative format spec
through the "--cover-letter-format" option. This option either takes
"shortlog", which is the current format, or a format spec prefixed with
"log:".
Example:
git format-patch --cover-letter \
--cover-letter-format="log:[%(count)/%(total)] %s (%an)" HEAD~3
[1/3] this is a commit summary (Mirko Faina)
[2/3] this is another commit summary (Mirko Faina)

The "files" backend is implemented as a pointer in the `struct
odb_source`. This contradicts our typical pattern for pluggable backends
like we use it for example in the ref store or for object database
streams, where we typically embed the generic base structure in the
specialized implementation. This pattern has a couple of small benefits:
- We avoid an extra allocation.
- We hide implementation details in the generic structure.
- We can easily downcast from a generic backend to the specialized
structure and vice versa because the offsets are known at compile
time.
- It becomes trivial to identify locations where we depend on backend
specific logic because the cast needs to be explicit.
Refactor our "files" object database source to do the same and embed the
`struct odb_source` in the `struct odb_source_files`.
There are still a bunch of sites in our code base where we do have to
access internals of the "files" backend. The intent is that those will
go away over time, but this will certainly take a while. Meanwhile,
provide a `odb_source_files_downcast()` function that can convert a
generic source into a "files" source.
As we only have a single source the downcast succeeds unconditionally
for now. Eventually though the intent is to make the cast `BUG()` in
case the caller requests to downcast a non-"files" backend to a "files"
backend.

Introduce a new "files" object database source. This source encapsulates
access to both loose object files and the packfile store, similar to how
the "files" backend for refs encapsulates access to loose refs and the
packed-refs file.
Note that for now the "files" source is still a direct member of a
`struct odb_source`. This architecture will be reversed in the next
commit so that the files source contains a `struct odb_source`.

As part of the conversion away from oidmap_clear(), switch the
missing_objects map to use oidmap_clear_with_free().
missing_objects stores struct missing_objects_map_entry instances,
which own an xstrdup()'d path string in addition to the container
struct itself. Previously, rev-list manually freed entry->path
before calling oidmap_clear(&missing_objects, true).
Introduce a dedicated free callback and pass it to
oidmap_clear_with_free(), consolidating entry teardown into a
single place and making cleanup semantics explicit.

When run in a worktree, the GIT_DIR directory is set in a different way
than in a typical repository. Show this by updating t0068 to include a
worktree and add a test that runs from that worktree. This requires
moving the repo.key config into a global config instead of the base test
repository's local config (demonstrating that it worked with
non-worktree Git repositories).
We need to be careful to unset the local Git environment variables and
let the child process rediscover them, while also reinstating those
variables in the parent process afterwards. Update run_command_on_repo()
to use the new sanitize_repo_env() helper method to erase these
environment variables.
During review of this bug fix, there were several incorrect patches
demonstrating different bad behaviors. Most of these are covered by
tests, when it is not too expensive to set it up. One case that would be
expensive to set up is the GIT_NO_REPLACE_OBJECTS environment variable,
but we trust that using sanitize_repo_env() will be sufficient to
capture these uncovered cases by using the common code for resetting
environment variables.

Exit early if the hooks do not exist, to avoid spinning up/down
sideband async threads which no-op.
It is important to call the hook_exists() API provided by hook.[ch]
because it covers both config-defined hooks and the "traditional"
hooks from the hookdir. find_hook() only covers the hookdir hooks.
The regression happened because the no-op async threads add some
additional overhead which can be measured with the receive-refs test
of the benchmarks suite [1].

The "structure" output for git-repo(1) shows the total inflated and disk
sizes of reachable objects in the repository, but doesn't show the size
of the largest individual objects. Since an individual object may be a
large contributor to the overall repository size, it is useful for users
to know the maximum size of individual objects.
While interating across objects, record the size and OID of the largest
objects encountered for each object type to provide as output. Note that

the corresponding OID. In a subsequent commit, the table format is
