path: convert strbuf_git_common_path to take a 'struct repository'
path: always pass in commondir to update_common_dir

environment: place key repository state in the_repository
repository: introduce the repository object
environment: remove namespace_len variable

The .gitmodules file is not supposed to have all the options available,
that are available in the configuration so separate it out.
A configuration option such as the hypothetical submodule.color.diff
that determines in which color a submodule change is printed,
is a very user specific thing, that the .gitmodules file should
not tamper with.
The .gitmodules file should only be used for settings that required
to setup the project in which the .gitmodules file is tracked. As the
minimum this would only include the name<->path mapping of the
submodule and its URL and branch.
Any further setting (such as 'fetch.recursesubmodules' or
'submodule.<name>.{update, ignore, shallow}') is not specific
to the project setup requirements, but rather is a distribution
of suggested developer configurations. In other areas of Git
a suggested developer configuration is not transported in-tree
but via other means. In an organisation this could be done
by deploying an opinionated system wide config (/etc/gitconfig)
or by putting the settings in the users home directory when
they start at the organisation. In open source projects this
is often accomplished via extensive READMEs (cf. our
SubmittingPatches/CodingGuidlines).
As a later patch in this series wants to introduce
a generic submodule recursion option, we want to make
sure that switch is not exposed via the gitmodules file.

The callback function is essentially duplicated 3 times. Remove all
of them and offer a new callback function, that lives in submodule.c
By putting the callback function there, we no longer need the function
'set_config_update_recurse_submodules', nor duplicate the global variable
in each builtin as well as submodule.c
In the three builtins we have different 2 ways how to load the .gitmodules
and config file, which are slightly different. git-checkout has to load
the submodule config all the time due to 23b4c7bcc5 (checkout: Use
submodule.*.ignore settings from .git/config and .gitmodules, 2010-08-28)
git-reset and git-read-tree do not respect these diff settings, so loading
the submodule configuration is optional. Also put that into submodule.c
for code deduplication.

Since (ae8d08242 pathspec: pass directory indicator to
match_pathspec_item()) the path matching logic has been able to cope
with submodules without needing to strip off a trailing slash if a path
refers to a submodule.
Since the stripping the trailing slash is no longer necessary, remove
the PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE flag. In addition, factor
out the logic which dies if a path decends into a submodule so that it
can still be used as a check after a pathspec struct has been
initialized.

Currently 'git add' is the only command which dies when launched from an
unpopulated submodule (the place-holder directory for a submodule which
hasn't been checked out). This is triggered implicitly by passing the
PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE flag to 'parse_pathspec()'.
Instead make this desire more explicit by creating a function
'die_in_unpopulated_submodule()' which dies if the provided 'prefix' has
a leading path component which matches a submodule in the the index.

Convert lookup_commit, lookup_commit_or_die,
lookup_commit_reference, and lookup_commit_reference_gently to take
struct object_id arguments.
Introduce a temporary in parse_object buffer in order to convert this
function. This is required since in order to convert parse_object and
parse_object_buffer, lookup_commit_reference_gently and
lookup_commit_or_die would need to be converted. Not introducing a
temporary would therefore require that lookup_commit_or_die take a
struct object_id *, but lookup_commit would take unsigned char *,
leaving a confusing and hard-to-use interface.
parse_object_buffer will lose this temporary in a later patch.

We forgot to prepare the submodule env, which is only a problem for
nested submodules. See 2e5d6503bd (ls-files: fix recurse-submodules
with nested submodules, 2017-04-13) for further explanation.
To come up with a proper test for this, we'd need to look at nested
submodules just as in that given commit. It turns out we're lucky
and these tests already exist, but are marked as failing. We need
to pass `--recurse-submodules` to read-tree additionally to make
these tests pass. Passing that flag alone would not make the tests
pass, such that this covers testing for the bug fix of the submodule
env as well.

There are currently two instances (fetch and push) where we want to
determine if submodules have changed given some revision specification.
These two instances don't use the same logic to generate a list of
changed submodules and as a result there is a fair amount of code
duplication.
This patch refactors these two code paths such that they both use the
same logic to generate a list of changed submodules. This also makes it
easier for future callers to be able to reuse this logic as they only
need to create an argv_array with the revision specification to be using
during the revision walk.

Early on in submodule_move_head just after the check if the submodule is
initialized, we need to check if the submodule is populated correctly.
If the submodule is initialized but doesn't look like it is populated,
this is a red flag and can indicate multiple sorts of failures:
(1) The submodule may be recorded at an object name, that is missing.
(2) The submodule '.git' file link may be broken and it is not pointing
at a repository.
In both cases we want to complain to the user in the non-forced mode,
and in the forced mode ignoring the old state and just moving the
submodule into its new state with a fixed '.git' file link.

This was an oversight when working on the working tree modifying commands
recursing into submodules.
To test for uninitialized submodules, introduce another submodule
"uninitialized_sub". Adding it via `submodule add` will activate the
submodule in the preparation area (in create_lib_submodule_repo we
setup all the things in submodule_update_repo), but the later tests
will use a new testing repo that clones the preparation repo
in which the new submodule is not initialized.
By adding it to the branch "add_sub1", which is the starting point of
all other branches, we have wide coverage.

Teach "push --recurse-submodules" to propagate, if given a name as remote, the
provided remote and refspec recursively to the pushes performed in the

remote with such a name configured.
Note that "push --recurse-submodules" with a path or URL as remote will not
propagate the remote or refspec and instead use the default remote and refspec
configured in the submodule, preserving the current behavior.

David reported:
> When I try to run `git diff --submodule=diff` in a submodule which has

This happens, because we do not properly initialize the environment
in which the diff is run in the submodule. That means we inherit the
environment from the main process, which sets environment variables.
(Apparently we do set environment variables which we do not set
when not in a submodules, i.e. the .git directory is linked)
This commit, just like fd47ae6a5b (diff: teach diff to display
submodule difference with an inline diff, 2016-08-31) introduces bad
test code (i.e. hard coded hash values), which will be cleanup up in

These calls to snprintf should always succeed, because their
input is small and fixed. Let's use xsnprintf to make sure
this is the case (and to make auditing for actual truncation
easier).
These could be candidates for turning into heap buffers, but
they fall into a few broad categories that make it not worth
doing:
- formatting single numbers is simple enough that we can
see the result should fit
- the size of a sha1 is likewise well-known, and I didn't
want to cause unnecessary conflicts with the ongoing
process to convert these constants to GIT_MAX_HEXSZ
- the interface for curl_errorstr is dictated by curl
