The function for_each_file_in_obj_subdir() takes a object subdirectory
number and expects the name of the same subdirectory to be included in
the path strbuf. Avoid this redundancy by letting the function append
the hexadecimal subdirectory name itself. This makes it a bit easier
and safer to use the function -- it becomes impossible to specify
different subdirectories in subdir_nr and path.

The resulting submodule 'struct repository' can be in one of three states:
1. The submodule is initialized and has a worktree.
2. The submodule is initialized but does not have a worktree. This
would occur when the submodule's gitdir is present in the
superproject's 'gitdir/modules/' directory yet the submodule has not
been checked out in superproject's worktree.
3. The submodule remains uninitialized due to an error in the
initialization process or there is no matching submodule at the
provided path in the superproject.

Teach the config machinery to read config information from a repository
object. This involves storing a 'struct config_set' inside the
repository object and adding a number of functions (repo_config*) to be
able to query a repository's config.
The current config API enables lazy-loading of the config. This means
that when 'git_config_get_int()' is called, if the_config_set hasn't
been populated yet, then it will be populated and properly initialized by
reading the necessary config files (system wide .gitconfig, user's home
.gitconfig, and the repository's config). To maintain this paradigm,
the new API to read from a repository object's config will also perform
this lazy-initialization.
Since both APIs (git_config_get* and repo_config_get*) have the same
semantics we can migrate the default config to be stored within
'the_repository' and just have the 'git_config_get*' family of functions
redirect to the 'repo_config_get*' functions.

git_path is a convenience function that usually produces a string
$GIT_DIR/<path>. Since v2.5.0-rc0~143^2~35 (git_path(): be aware of
file relocation in $GIT_DIR, 2014-11-30), as a side benefit callers
get support for path relocation variables like $GIT_OBJECT_DIRECTORY:
- git_path("index") is $GIT_INDEX_FILE when set
- git_path("info/grafts") is $GIT_GRAFTS_FILE when set
- git_path("objects/<foo>") is $GIT_OBJECT_DIRECTORY/<foo> when set
- git_path("hooks/<foo>") is <foo> under core.hookspath when set
- git_path("refs/<foo>") etc (see path.c::common_list) is relative
to $GIT_COMMON_DIR instead of $GIT_DIR
worktree_git_path, by comparison, is designed to resolve files in a
specific worktree's git dir. Unfortunately, it shares code with
git_path and performs the same relocation. The result is that paths
that are meant to be relative to the specified worktree's git dir end
up replaced by paths from environment variables within the current git
dir.
Luckily, no current callers pass such arguments. The relocation was
noticed when testing the result of merging two patches under review,
one of which introduces a caller:
* The first patch made git prune check the index file in each
worktree's git dir (using worktree_git_path(wt, "index")) for
objects not to prune. This would trigger the unwanted relocation
when GIT_INDEX_FILE is set, causing objects reachable from the
index to be pruned.
* The second patch simplified the relocation logic for index,
info/grafts, objects, and hooks to happen unconditionally instead of
based on whether environment or configuration variables are set.
This caused the relocation to trigger even when GIT_INDEX_FILE is
not set.
[jn: rewrote commit message; skipping all relocation instead of just
GIT_INDEX_FILE]

Introduce the repository object 'struct repository' which can be used to
hold all state pertaining to a git repository.
Some of the benefits of object-ifying a repository are:
1. Make the code base more readable and easier to reason about.
2. Allow for working on multiple repositories, specifically
submodules, within the same process. Currently the process for
working on a submodule involves setting up an argv_array of options
for a particular command and then launching a child process to
execute the command in the context of the submodule. This is
clunky and can require lots of little hacks in order to ensure
correctness. Ideally it would be nice to simply pass a repository
and an options struct to a command.
3. Eliminating reliance on global state will make it easier to
enable the use of threading to improve performance.

Under some circumstances (bogus GIT_DIR value or the discovered gitdir
is '.git') 'setup_git_directory()' won't initialize key repository
state. This leads to inconsistent state after running the setup code.
To account for this inconsistent state, lazy initialization is done once
a caller asks for the repository's gitdir or some other piece of
repository state. This is confusing and can be error prone.
Instead let's tighten the expected outcome of 'setup_git_directory()'
and ensure that it initializes repository state in all cases that would
have been handled by lazy initialization.
This also lets us drop the requirement to have 'have_git_dir()' check if
the environment variable GIT_DIR was set as that will be handled by the
end of the setup code.

Teach pull to optionally update submodules when '--recurse-submodules'
is provided. This will teach pull to run 'submodule update --rebase'
when the '--recurse-submodules' and '--rebase' flags are given under
specific circumstances.
On a rebase workflow:
=====================
1. Both sides change the submodule
------------------------------
Let's assume the following history in a submodule:
H---I---J---K---L local branch
\
M---N---O---P remote branch
and the following in the superproject (recorded submodule in parens):
A(H)---B(I)---F(K)---G(L) local branch
\
C(N)---D(N)---E(P) remote branch
In an ideal world this would rebase the submodule and rewrite
the submodule pointers that the superproject points at such that
the superproject looks like
A(H)---B(I) F(K')---G(L') rebased branch
\ /
C(N)---D(N)---E(P) remote branch
and the submodule as:
J---K---L (old dangeling tip)
/
H---I J'---K'---L' rebased branch
\ /
M---N---O---P remote branch
And if a conflict arises in the submodule the superproject rebase
would stop at that commit at which the submodule conflict occurs.
Currently a "pull --rebase" in the superproject produces
a merge conflict as the submodule pointer changes are
conflicting and cannot be resolved.
2. Local submodule changes only
-----------------------
Assuming histories as above, except that the remote branch
would not contain submodule changes, then a result as
A(H)---B(I) F(K)---G(L) rebased branch
\ /
C(I)---D(I)---E(I) remote branch
is desire-able. This is what currently happens in rebase.
If the recursive flag is given, the ideal git would
produce a superproject as:
A(H)---B(I) F(K')---G(L') rebased branch (incl. sub rebase!)
\ /
C(I)---D(I)---E(I) remote branch
and the submodule as:
J---K---L (old dangeling tip)
/
H---I J'---K'---L' locally rebased branch
\ /
M---N---O---P advanced branch
This patch doesn't address this issue, however
a test is added that this fails up front.
3. Remote submodule changes only
----------------------
Assuming histories as in (1) except that the local superproject branch
would not have touched the submodule the rebase already works out in the
superproject with no conflicts:
A(H)---B(I) F(P)---G(P) rebased branch (no sub changes)
\ /
C(N)---D(N)---E(P) remote branch
The recurse flag as presented in this patch would additionally
update the submodule as:
H---I J'---K'---L' rebased branch
\ /
M---N---O---P remote branch
As neither J, K, L nor J', K', L' are referred to from the superproject,
no rewriting of the superproject commits is required.
Conclusion for 'pull --rebase --recursive'
-----------------------------------------
If there are no local superproject changes it is sufficient to call
"submodule update --rebase" as this produces the desired results. In case
of conflicts, the behavior is the same as in 'submodule update --recursive'
which is assumed to be sane.
This patch implements (3) only.
On a merge workflow:
====================
We'll start off with the same underlying DAG as in (1) in the rebase
workflow. So in an ideal world a 'pull --merge --recursive' would
produce this:
H---I---J---K---L----X
\ /
M---N---O---P
with X as the new merge-commit in the submodule and the superproject
as:
A(H)---B(I)---F(K)---G(L)---Y(X)
\ /
C(N)---D(N)---E(P)
However modifying the submodules on the fly is not supported in git-merge
such that Y(X) is not easy to produce in a single patch. In fact git-merge
doesn't know about submodules at all.
However when at least one side does not contain commits touching the
submodule at all, then we do not need to perform the merge for the
submodule but a fast-forward can be done via checking out either L or P
in the submodule. This strategy is implemented in 68d03e4a6e (Implement
automatic fast-forward merge for submodules, 2010-07-07) already, so
to align with the rebase behavior we need to also update the worktree
of the submodule.
