Similar to the preceding commit, introduce counting of objects on the
object database level, replacing the logic that we have in
`repo_approximate_object_count()`.
Note that the function knows to cache the object count. It's unclear
whether this cache is really required as we shouldn't have that many
cases where we count objects repeatedly. But to be on the safe side the
caching mechanism is retained, with the only excepting being that we
also have to use the passed flags as caching key.

In "builtin/gc.c" we have some logic that checks whether we need to
repack objects. This is done by counting the number of objects that we
have and checking whether it exceeds a certain threshold. We don't
really need an accurate object count though, which is why we only
open a single object diretcroy shard and then extrapolate from there.
Extract this logic into a new function that is owned by the loose object
database source. This is done to prepare for a subsequent change, where
we'll introduce object counting on the object database source level.

The "odb.h" header currently includes the "odb/source.h" file. This is
somewhat roundabout though: most callers shouldn't have to care about
the `struct odb_source`, but should rather use the ODB-level functions.
Furthermore, it means that a couple of definitions have to live on the
source level even though they should be part of the generic interface.
Reverse the relation between "odb/source.h" and "odb.h" and move the
enums and typedefs that relate to the generic interfaces back into
"odb.h". Add the necessary includes to all files that rely on the
transitive include.

When running `git pack-objects --stdout` we feed the data through
`hashfd_ext()` with a progress meter and a smaller-than-usual buffer
length of 8kB so that we can track throughput more granularly. But as
packfiles tend to be on the larger side, this small buffer size may
cause a ton of write(3p) syscalls.
Originally, the buffer we used in `hashfd()` was 8kB for all use cases.
This was changed though in 2ca245f8be (csum-file.h: increase hashfile
buffer size, 2021-05-18) because we noticed that the number of writes
can have an impact on performance. So the buffer size was increased to
128kB, which improved performance a bit for some use cases.
But the commit didn't touch the buffer size for `hashd_throughput()`.
The reasoning here was that callers expect the progress indicator to
update frequently, and a larger buffer size would of course reduce the
update frequency especially on slow networks.
While that is of course true, there was (and still is, even though it's
now a call to `hashfd_ext()`) only a single caller of this function in
git-pack-objects(1). This command is responsible for writing packfiles,
and those packfiles are often on the bigger side. So arguably:
- The user won't care about increments of 8kB when packfiles tend to
be megabytes or even gigabytes in size.
- Reducing the number of syscalls would be even more valuable here
than it would be for multi-pack indices, which was the benchmark
done in the mentioned commit, as MIDXs are typically significantly
smaller than packfiles.
- Nowadays, many internet connections should be able to transfer data
at a rate significantly higher than 8kB per second.
Update the buffer to instead have a size of `LARGE_PACKET_DATA_MAX - 1`,
which translates to ~64kB. This limit was chosen because `git
pack-objects --stdout` is most often used when sending packfiles via
git-upload-pack(1), where packfile data is chunked into pktlines when
using the sideband. Furthermore, most internet connections should have a
bandwidth signifcantly higher than 64kB/s, so we'd still be able to
observe progress updates at a rate of at least once per second.
This change significantly reduces the number of write(3p) syscalls from
355,000 to 44,000 when packing the Linux repository. While this results
in a small performance improvement on an otherwise-unused system, this
improvement is mostly negligible. More importantly though, it will
reduce lock contention in the kernel on an extremely busy system where
we have many processes writing data at once.

The `hashfd_throughput()` function is used by a single callsite in
git-pack-objects(1). In contrast to `hashfd()`, this function uses a
progress meter to measure throughput and a smaller buffer length so that
the progress meter can provide more granular metrics.
We're going to change that caller in the next commit to be a bit more
specific to packing objects. As such, `hashfd_throughput()` will be a
somewhat unfitting mechanism for any potential new callers.
Drop the function and replace it with a call to `hashfd_ext()`.

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

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.

When the fsmonitor daemon is spawned as a background process, it may
inherit file descriptors from its parent that it does not need. In
particular, when the test harness or a CI system captures output through
pipes, the daemon can inherit duplicated pipe endpoints. If the daemon
holds these open, the parent process never sees EOF and may appear to
hang.
Set close_fd_above_stderr on the child process at both daemon startup
paths: the explicit "fsmonitor--daemon start" command and the implicit
spawn triggered by fsmonitor-ipc when a client finds no running daemon.
Also suppress stdout and stderr on the implicit spawn path to prevent
the background daemon from writing to the client's terminal.
Additionally, call setsid() when the daemon starts with --detach to
create a new session and process group. This prevents the daemon
from being part of the spawning shell's process group, which could
cause the shell's "wait" to block until the daemon exits.

label, skipping the kh_release_str() call entirely and leaking the
hash table.
Fix this by initializing `shown` to NULL and moving the cleanup to the
