3c3558f095 submodule--helper: run update using child process struct
We switch to using the run-command API function that takes a
'struct child process', since we are using a lot of the options. This
will also make it simple to switch over to using 'capture_command()'
when we start handling the output of the command completely in C.

c9d2562493 submodule--helper update-clone: check for --filter and --init
"git submodule update --filter" also requires the "--init" option. Teach
update-clone to do this usage check in C and remove the check from
git-submodule.sh.

In addition, change update-clone's usage string so that it teaches users
about "git submodule update" instead of "git submodule--helper
update-clone" (the string is copied from git-submodule.sh). This should
be more helpful to users since they don't invoke update-clone directly.

97cb977c82 submodule--helper: remove ensure-core-worktree
Move the logic of "git submodule--helper ensure-core-worktree" into
run-update-procedure, and since this makes the ensure-core-worktree
command obsolete, remove it.

As a result, the order of two operations in git-submodule.sh is
reversed: 'set the value of core.worktree' now happens after the call to
"git submodule--helper relative-path". This is safe - "relative-path"
does not depend on the value of core.worktree.

29a5e9e1ff submodule--helper update-clone: learn --init
Teach "git submodule--helper update-clone" the --init flag and remove
the corresponding shell code.

When the `--init` flag is passed to the subcommand, we do not spawn a
new subprocess and call `submodule--helper init` on the submodule paths,
because the Git machinery is not able to pick up the configuration
changes introduced by that init call. So we instead run the
`init_submodule_cb()` callback over each submodule in the same process.

3ce52cba5b submodule--helper: allow setting superprefix for init_submodule()
We allow callers of the `init_submodule()` function to optionally
override the superprefix from the environment.

We need to enable this option because in our conversion of the update
command that will follow, the '--init' option will be handled through
this API. We will need to change the superprefix at that time to ensure
the display paths show correctly in the output messages.

a77c3fcb5e submodule--helper: get remote names from any repository
`get_default_remote()` retrieves the name of a remote by resolving the
refs from of the current repository's ref store.

Thus in order to use it for retrieving the remote name of a submodule,
we have to start a new subprocess which runs from the submodule
directory.

Let's instead introduce a function called `repo_get_default_remote()`
which takes any repository object and retrieves the remote accordingly.

`get_default_remote()` is then defined as a call to
`repo_get_default_remote()` with 'the_repository' passed to it.

Now that we have `repo_get_default_remote()`, we no longer have to start
a subprocess that called `submodule--helper get-default-remote` from
within the submodule directory.

So let's make a function called `get_default_remote_submodule()` which
takes a submodule path, and returns the default remote for that
submodule, all within the same process.

We can now use this function to save an unnecessary subprocess spawn in
`sync_submodule()`, and also in a subsequent patch, which will require
this functionality.

759f340738 repository.c: free the "path cache" in repo_clear()
The "struct path_cache" added in 102de880d2 (path.c: migrate global
git_path_* to take a repository argument, 2018-05-17) is only used
directly by code in repository.[ch] (but populated in path.[ch]).

Let's move this code to repository.[ch], and stop leaking this memory
when we run repo_clear(). To avoid the cast change it from a "const
char *" to a "char *".

This also removes the "PATH_CACHE_INIT" macro, which has never been
used for anything. For the "struct repository" we already make a hard
assumption that it (and "the_repository") can be identically
initialized by making it a "static" variable, so making use of a
"PATH_CACHE_INIT" somewhere would have been confusing.

2d102c2bca range-diff: plug memory leak in read_patches()
Amend code added in d9c66f0b5b (range-diff: first rudimentary
implementation, 2018-08-13) to use a "goto cleanup" pattern. This
makes for less code, and frees memory that we'd previously leak.

The reason for changing free(util) to FREE_AND_NULL(util) is because
at the end of the function we append the contents of "util" to a
"struct string_list" if it's non-NULL.

4998e93fa6 range-diff: plug memory leak in common invocation
Create a public release_patch() version of the private free_patch()
function added in 13b5af22f3 (apply: move libified code from
builtin/apply.c to apply.{c,h}, 2016-04-22). Unlike the existing
function this one doesn't free() the "struct patch" itself, so we can
use it for variables on the stack.

Use it in range-diff.c to fix a memory leak in common range-diff
invocations, e.g.:

    git -P range-diff origin/master origin/next origin/seen

Would emit several errors when compiled with SANITIZE=leak, but now
runs cleanly.

ef3fe21448 lockfile API users: simplify and don't leak "path"
Fix a memory leak in code added in 6c622f9f0b (commit-graph: write
commit-graph chains, 2019-06-18). We needed to free the "lock_name" if
we encounter errors, and the "graph_name" after we'd run unlink() on
it.

For the case of write_commit_graph_file() refactoring the code to free
the "lock_name" after we were done using the "struct lock_file lk"
would have made the control flow more complex. Luckily we can free the
"lock_file" right after the hold_lock_file_for_update() call, if it
makes use of "path" at all it'll have copied its contents to a "struct
strbuf" of its own.

While I'm at it let's fix code added in fb10ca5b54 (sparse-checkout:
write using lockfile, 2019-11-21) in write_patterns_and_update() to
avoid the same complexity that I thought I needed when I wrote the
initial fix for write_commit_graph_file(). We can free the
"sparse_filename" right after calling hold_lock_file_for_update(), we
don't need to wait until we're exiting the function to do so.
