Migrate all git_path_* functions that are defined in path.c to take a
repository argument. Unlike other patches in this series, do not use the
#define trick, as we rewrite the whole function, which is rather small.
This doesn't migrate all the functions, as other builtins have their own
local path functions defined using GIT_PATH_FUNC. So keep that macro
around to serve the other locations.

Add a repository argument to allow callers of is_repository_shallow
to be more specific about which repository to handle. This is a small
mechanical change; it doesn't change the implementation to handle
repositories other than the_repository yet.
As with the previous commits, use a macro to catch callers passing a
repository other than the_repository at compile time.

This should make these functions easier to find and cache.h less
overwhelming to read.
In particular, this moves:
- read_object_file
- oid_object_info
- write_object_file
As a result, most of the codebase needs to #include object-store.h.
In this patch the #include is only added to files that would fail to
compile otherwise. It would be better to #include wherever
identifiers from the header are used. That can happen later
when we have better tooling for it.

The reason callers have to call this is to make sure either packed_git
or packed_git_mru pointers are initialized since we don't do that by
default. Sometimes it's hard to see this connection between where the
function is called and where packed_git pointer is used (sometimes in
separate functions).
Keep this dependency internal because now all access to packed_git and
packed_git_mru must go through get_xxx() wrappers.

The raw object store field will contain any objects needed for access
to objects in a given repository.
This patch introduces the raw object store and populates it with the
`objectdir`, which used to be part of the repository struct.
As the struct gains members, we'll also populate the function to clear
the memory for these members.
In a later step, we'll introduce a struct object_parser, that will
complement the object parsing in a repository struct: The raw object
parser is the layer that will provide access to raw object content,
while the higher level object parser code will parse raw objects and
keeps track of parenthood and other object relationships using 'struct
object'. For now only add the lower level to the repository struct.

The 'self-initialised' variables construct (ie <type> var = var;) has
been used to silence gcc '-W[maybe-]uninitialized' warnings. This has,
unfortunately, caused MSVC to issue 'uninitialized variable' warnings.
Also, using clang static analysis causes complaints about an 'Assigned
value is garbage or undefined'.
There are six such constructs in the current codebase. Only one of the
six causes gcc to issue a '-Wmaybe-uninitialized' warning (which will
be addressed elsewhere). The remaining five 'init-self' gcc workarounds
are noted below, along with the commit which introduced them:
1. builtin/rev-list.c: 'reaches' and 'all', see commit 457f08a030
("git-rev-list: add --bisect-vars option.", 2007-03-21).
2. merge-recursive.c:2064 'mrtree', see commit f120ae2a8e ("merge-
recursive.c: mrtree in merge() is not used before set", 2007-10-29).
3. fast-import.c:3023 'oe', see commit 85c62395b1 ("fast-import: let
importers retrieve blobs", 2010-11-28).
4. fast-import.c:3006 'oe', see commit 28c7b1f7b7 ("fast-import: add a
get-mark command", 2015-07-01).

Automatic detection of worktree relocation by a user (via 'mv', for
instance) was removed by 618244e160 (worktree: stop supporting moving
worktrees manually - 2016-01-22). Prior to that,
.git/worktrees/<tag>/gitdir was updated whenever the worktree was
accessed in order to let the pruning logic know that the worktree was
"active" even if it disappeared for a while (due to being located on
removable media, for instance).
"git worktree move" has come so we don't really need this, but since
it's easy to do, perhaps we could keep supporting manual worktree move
a bit longer. Notice that when a worktree is active, the "index" file
should be updated pretty often in common case. The logic is updated to
check for index mtime to see if the worktree is alive.
The old logic of checking gitdir's mtime is dropped because nobody
updates it anyway. The new corner case is, if the index file does not
exist, we immediately remove the stale worktree. But if the "index"
file does not exist, you may have a bigger problem.

This "link" was a feature in early iterations of multiple worktree
functionality for some reason it was dropped [1]. Since nobody creates
this "link", there's no need to check it.
This is mostly used to let the user moves a worktree manually [2]. If
you move a worktree within the same file system, this hard link count
lets us know the worktree is still there even if we don't know where it
is.
We support 'worktree move' now and don't need this anymore.

If we are outside a repo and have any arguments left after

something like this will happen:

The usage is wrong, but we could obviously handle this better. Note that
commit abe549e179 (shortlog: do not require to run from inside a git
repository, 2008-03-14) explicitly enabled `git shortlog` to run from
outside a repo, since we do not need a repo for parsing data from stdin.
