submodule-config: verify submodule names as paths
Submodule "names" come from the untrusted .gitmodules file,
but we blindly append them to $GIT_DIR/modules to create our
on-disk repo paths. This means you can do bad things by
putting "../" into the name (among other things).
Let's sanity-check these names to avoid building a path that
can be exploited. There are two main decisions:
1. What should the allowed syntax be?
It's tempting to reuse verify_path(), since submodule
names typically come from in-repo paths. But there are
two reasons not to:
a. It's technically more strict than what we need, as
we really care only about breaking out of the
$GIT_DIR/modules/ hierarchy. E.g., having a
submodule named "foo/.git" isn't actually
dangerous, and it's possible that somebody has
manually given such a funny name.
b. Since we'll eventually use this checking logic in
fsck to prevent downstream repositories, it should
be consistent across platforms. Because
verify_path() relies on is_dir_sep(), it wouldn't
block "foo\..\bar" on a non-Windows machine.
2. Where should we enforce it? These days most of the
.gitmodules reads go through submodule-config.c, so
I've put it there in the reading step. That should
cover all of the C code.
We also construct the name for "git submodule add"
inside the git-submodule.sh script. This is probably
not a big deal for security since the name is coming
from the user anyway, but it would be polite to remind
them if the name they pick is invalid (and we need to
expose the name-checker to the shell anyway for our
test scripts).
This patch issues a warning when reading .gitmodules
and just ignores the related config entry completely.
This will generally end up producing a sensible error,
as it works the same as a .gitmodules file which is
missing a submodule entry (so "submodule update" will
barf, but "git clone --recurse-submodules" will print
an error but not abort the clone.
There is one minor oddity, which is that we print the
warning once per malformed config key (since that's how
the config subsystem gives us the entries). So in the
new test, for example, the user would see three
warnings. That's OK, since the intent is that this case
should never come up outside of malicious repositories
(and then it might even benefit the user to see the
message multiple times).
Credit for finding this vulnerability and the proof of
concept from which the test script was adapted goes to
Etienne Stalmans.

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.

In order to use the submodule-config subsystem, callers first need to
initialize it by calling 'repo_read_gitmodules()' or
'gitmodules_config()' (which just redirects to
'repo_read_gitmodules()'). There are a couple of callers who need to
load an explicit revision of the repository's .gitmodules file (grep) or
need to modify the .gitmodules file so they would need to load it before
modify the file (checkout), but the majority of callers are simply
reading the .gitmodules file present in the working tree. For the
common case it would be nice to avoid the boilerplate of initializing
the submodule-config system before using it, so instead let's perform
lazy-loading of the submodule-config system.
Remove the calls to reading the gitmodules file from ls-files to show

hashmap: migrate documentation from Documentation/technical into header
patch-ids.c: use hashmap correctly
hashmap.h: compare function has access to a data field
When using the hashmap a common need is to have access to caller provided
data in the compare function. A couple of times we abuse the keydata field
to pass in the data needed. This happens for example in patch-ids.c.
This patch changes the function signature of the compare function
to have one more void pointer available. The pointer given for each
invocation of the compare function must be defined in the init function
of the hashmap and is just passed through.
Documentation of this new feature is deferred to a later patch.
This is a rather mechanical conversion, just adding the new pass-through
parameter. However while at it improve the naming of the fields of all
compare functions used by hashmaps by ensuring unused parameters are
prefixed with 'unused_' and naming the parameters what they are (instead
of 'unused' make it 'unused_keydata').

Introduced in 473166b ("config: add 'origin_type' to config_source
struct", 2016-02-19), Git can inform the user about the origin of a
config error, but the implementation does not allow translators to
translate the keywords 'file', 'blob, 'standard input', and
'submodule-blob'. Moreover, for the second message, a reason for the
error is appended to the message, not allowing translators to translate
that reason either.
Unfold the message into several templates for each known origin_type.
That would result in better translation at the expense of code
verbosity.
Add enum config_oringin_type to ease management of the various
configuration origin types (blob, file, etc). Previously origin type
was considered from command line if cf->origin_type == NULL, i.e.,
uninitialized. Now we set origin_type to CONFIG_ORIGIN_CMDLINE in
git_config_from_parameters() and configset_add_value().
For error message in git_parse_source(), use xstrfmt() function to
prepare the message string, instead of doing something like it's done
for die_bad_number(), because intelligibility and code conciseness are
improved for that instance.

Lots of internal functions in submodule-confic.c have a first parameter
`struct submodule_cache *cache`, which currently always refers to the
global variable `cache` in the file. To avoid confusion rename the
global `cache` variable.

A major part of "git submodule update" has been ported to C to take
advantage of the recently added framework to run download tasks in
parallel.
* sb/submodule-parallel-update:
clone: allow an explicit argument for parallel submodule clones
submodule update: expose parallelism to the user
submodule helper: remove double 'fatal: ' prefix
git submodule update: have a dedicated helper for cloning
run_processes_parallel: rename parameters for the callbacks
run_processes_parallel: treat output of children as byte array
submodule update: direct error message to stderr
fetching submodules: respect `submodule.fetchJobs` config option
submodule-config: drop check against NULL
submodule-config: keep update strategy around
The hashmap API provides hashmap_iter_first() helper for initialion
and getting the first entry of a hashmap. Let's use it instead of
doing initialization manually and then get the first entry.
There are no functional changes, just cleanup.

Adhere to the common coding style of Git and not check explicitly
for NULL throughout the file. There are still other occurrences in the
code base but that is usually inside of conditions with side effects.

Currently submodule.<name>.update is only handled by git-submodule.sh.
C code will start to need to make use of that value as more of the
functionality of git-submodule.sh moves into library code in C.
Add the update field to 'struct submodule' and populate it so it can
be read as sm->update or from sm->update_command.

Use the config origin_type to print more detailed error messages that
inform the user about the origin of a config error (file, stdin, blob).

The --recurse-submodules command line parameter has existed for some
time but it has no config file equivalent.
Following the style of the corresponding parameter for git fetch, let's
invent push.recurseSubmodules to provide a default for this
parameter. This also requires the addition of --recurse-submodules=no to
allow the configuration to be overridden on the command line when
required.
The most straightforward way to implement this appears to be to make
push use code in submodule-config in a similar way to fetch.

Many components in if/else if/... cascade jumped to a shared
clean-up with "goto release_return", but we can restructure the
function a bit and make them disappear, which reduces the line count
as well. Also reformat overlong lines and poorly indented ones
while at it.
The order of rules to verify the value for "ignore" used to be to
complain on multiple values first and then complain to boolean, but
swap the order to match how the values for "path" and "url" are
verified.

We should not die when reading the submodule config cache since the
user might not be able to get out of that situation when the
configuration is part of the history.
We should handle this condition later when the value is about to be
used.

We remove the extracted functions and directly parse into and read out
of the cache. This allows us to have one unified way of accessing
submodule configuration values specific to single submodules. Regardless
whether we need to access a configuration from history or from the
worktree.

In a superproject some commands need to interact with submodules. They
need to query values from the .gitmodules file either from the worktree
of from certain revisions. At the moment this is quite hard since a
caller would need to read the .gitmodules file from the history and then
parse the values. We want to provide an API for this so we have one
place to get values from .gitmodules from any revision (including the
worktree).
The API is realized as a cache which allows us to lazily read
.gitmodules configurations by commit into a runtime cache which can then
be used to easily lookup values from it. Currently only the values for
path or name are stored but it can be extended for any value needed.
It is expected that .gitmodules files do not change often between
commits. Thats why we lookup the .gitmodules sha1 from a commit and then
either lookup an already parsed configuration or parse and cache an
unknown one for each sha1. The cache is lazily build on demand for each
requested commit.
This cache can be used for all purposes which need knowledge about
submodule configurations. Example use cases are:
* Recursive submodule checkout needs to lookup a submodule name from
its path when a submodule first appears. This needs be done before
this configuration exists in the worktree.
* The implementation of submodule support for 'git archive' needs to
lookup the submodule name to generate the archive when given a
revision that is not checked out.
* 'git fetch' when given the --recurse-submodules=on-demand option (or
configuration) needs to lookup submodule names by path from the
database rather than reading from the worktree. For new submodule it
needs to lookup the name from its path to allow cloning new
submodules into the .git folder so they can be checked out without
any network interaction when the user does a checkout of that
revision.
