submodule: decouple url and submodule interest
Currently the submodule.<name>.url config option is used to determine if
a given submodule is of interest to the user. This ends up being
cumbersome in a world where we want to have different submodules checked
out in different worktrees or a more generalized mechanism to select
which submodules are of interest.
In a future with worktree support for submodules, there will be multiple
working trees, each of which may only need a subset of the submodules
checked out. The URL (which is where the submodule repository can be
obtained) should not differ between different working trees.
It may also be convenient for users to more easily specify groups of
submodules they are interested in as opposed to running "git submodule
init <path>" on each submodule they want checked out in their working
tree.
To this end two config options are introduced, submodule.active and
submodule.<name>.active. The submodule.active config holds a pathspec
that specifies which submodules should exist in the working tree. The
submodule.<name>.active config is a boolean flag used to indicate if
that particular submodule should exist in the working tree.
Its important to note that submodule.active functions differently than
the other configuration options since it takes a pathspec. This allows
users to adopt at least two new workflows:
1. Submodules can be grouped with a leading directory, such that a
pathspec e.g. 'lib/' would cover all library-ish modules to allow
those who are interested in library-ish modules to set
"submodule.active = lib/" just once to say any and all modules in
'lib/' are interesting.
2. Once the pathspec-attribute feature is invented, users can label
submodules with attributes to group them, so that a broad pathspec
with attribute requirements, e.g. ':(attr:lib)', can be used to say
any and all modules with the 'lib' attribute are interesting.
Since the .gitattributes file, just like the .gitmodules file, is
tracked by the superproject, when a submodule moves in the
superproject tree, the project can adjust which path gets the
attribute in .gitattributes, just like it can adjust which path has
the submodule in .gitmodules.
Neither of these two additional configuration options solve the problem
of wanting different submodules checked out in different worktrees
because multiple worktrees share .git/config. Only once per-worktree
configurations become a reality can this be solved, but this is a
necessary preparatory step for that future.
Given these multiple ways to check if a submodule is of interest, the
more fine-grained submodule.<name>.active option has the highest order
of precedence followed by the pathspec check against submodule.active.
To ensure backwards compatibility, if neither of these options are set,
git falls back to checking the submodule.<name>.url option to determine
if a submodule is interesting.

init <path>" on each submodule they want checked out in their working
tree.
To this end two config options are introduced, submodule.active and
submodule.<name>.active. The submodule.active config holds a pathspec
that specifies which submodules should exist in the working tree. The
submodule.<name>.active config is a boolean flag used to indicate if
that particular submodule should exist in the working tree.
Its important to note that submodule.active functions differently than
the other configuration options since it takes a pathspec. This allows
users to adopt at least two new workflows:
1. Submodules can be grouped with a leading directory, such that a
pathspec e.g. 'lib/' would cover all library-ish modules to allow
those who are interested in library-ish modules to set
"submodule.active = lib/" just once to say any and all modules in
'lib/' are interesting.
2. Once the pathspec-attribute feature is invented, users can label
submodules with attributes to group them, so that a broad pathspec
with attribute requirements, e.g. ':(attr:lib)', can be used to say
any and all modules with the 'lib' attribute are interesting.
Since the .gitattributes file, just like the .gitmodules file, is
tracked by the superproject, when a submodule moves in the
superproject tree, the project can adjust which path gets the
attribute in .gitattributes, just like it can adjust which path has
the submodule in .gitmodules.
Neither of these two additional configuration options solve the problem
of wanting different submodules checked out in different worktrees
because multiple worktrees share .git/config. Only once per-worktree
configurations become a reality can this be solved, but this is a
necessary preparatory step for that future.
Given these multiple ways to check if a submodule is of interest, the
more fine-grained submodule.<name>.active option has the highest order
of precedence followed by the pathspec check against submodule.active.
To ensure backwards compatibility, if neither of these options are set,
git falls back to checking the submodule.<name>.url option to determine
if a submodule is interesting.

submodule: decouple url and submodule interest
Currently the submodule.<name>.url config option is used to determine if
a given submodule is of interest to the user. This ends up being
cumbersome in a world where we want to have different submodules checked
out in different worktrees or a more generalized mechanism to select
which submodules are of interest.
In a future with worktree support for submodules, there will be multiple
working trees, each of which may only need a subset of the submodules
checked out. The URL (which is where the submodule repository can be
obtained) should not differ between different working trees.
It may also be convenient for users to more easily specify groups of
submodules they are interested in as opposed to running "git submodule

submodule: port init from shell to C
By having the `submodule init` functionality in C, we can reference it
easier from other parts in the code in later patches. The code is split
up to have one function to initialize one submodule and a calling function
that takes care of the rest, such as argument handling and translating the
arguments to the paths of the submodules.
This is the first submodule subcommand that is fully converted to C
except for the usage string, so this is actually removing a call to
the `submodule--helper list` function, which is supposed to be used in
this transition. Instead we'll make a direct call to `module_list_compute`.
An explanation why we need to edit the prefixes in cmd_update in
git-submodule.sh in this patch:
By having no processing in the shell part, we need to convey the notion
of wt_prefix and prefix to the C parts, which former patches punted on
and did the processing of displaying path in the shell.
`wt_prefix` used to hold the path from the repository root to the current
directory, e.g. wt_prefix would be t/ if the user invoked the
`git submodule` command in ~/repo/t and ~repo is the GIT_DIR.
`prefix` used to hold the relative path from the repository root to the
operation, e.g. if you have recursive submodules, the shell script would
modify the `prefix` in each recursive step by adding the submodule path.
We will pass `wt_prefix` into the C helper via `git -C <dir>` as that
will setup git in the directory the user actually called git-submodule.sh
from. The `prefix` will be passed in via the `--prefix` option.
Having `prefix` and `wt_prefix` relative to the GIT_DIR of the
calling superproject is unfortunate with this patch as the C code doesn't
know about a possible recursion from a superproject via `submodule update
--init --recursive`.
To fix this, we change the meaning of `wt_prefix` to point to the current
project instead of the superproject and `prefix` to include any relative
paths issues in the superproject. That way `prefix` will become the leading
part for displaying paths and `wt_prefix` will be empty in recursive
calls for now.
The new notion of `wt_prefix` and `prefix` still allows us to reconstruct
the calling directory in the superproject by just traveling reverse of
`prefix`.

convert "enum date_mode" into a struct
In preparation for adding date modes that may carry extra
information beyond the mode itself, this patch converts the
date_mode enum into a struct.
Most of the conversion is fairly straightforward; we pass
the struct as a pointer and dereference the type field where
necessary. Locations that declare a date_mode can use a "{}"
constructor. However, the tricky case is where we use the
enum labels as constants, like:
show_date(t, tz, DATE_NORMAL);
Ideally we could say:
show_date(t, tz, &{ DATE_NORMAL });
but of course C does not allow that. Likewise, we cannot
cast the constant to a struct, because we need to pass an
actual address. Our options are basically:
1. Manually add a "struct date_mode d = { DATE_NORMAL }"
definition to each caller, and pass "&d". This makes
the callers uglier, because they sometimes do not even
have their own scope (e.g., they are inside a switch
statement).
2. Provide a pre-made global "date_normal" struct that can
be passed by address. We'd also need "date_rfc2822",
"date_iso8601", and so forth. But at least the ugliness
is defined in one place.
3. Provide a wrapper that generates the correct struct on
the fly. The big downside is that we end up pointing to
a single global, which makes our wrapper non-reentrant.
But show_date is already not reentrant, so it does not
matter.
This patch implements 3, along with a minor macro to keep
the size of the callers sane.
