Code to read submodule.<name>.ignore config did not state the

submodule-config: correct error reporting for invalid ignore value
|

Similar to b33a15b08 (push: add recurseSubmodules config option,
2015-11-17) and 027771fcb1 (submodule: allow erroneous values for the
fetchRecurseSubmodules option, 2015-08-17), we add submodule-config code
that is later used to parse whether we are interested in updating
submodules.
We need the `die_on_error` parameter to be able to call this parsing
function for the config file as well, which if incorrect lets Git die.
As we're just touching the header file, also mark all functions extern.

Commit 959b5455 (submodule: implement a config API for lookup of
.gitmodules values, 2015-08-18) implemented the initial version of the
submodule config cache. During development of that initial version we
extracted the function gitmodule_sha1_from_commit(). During that process
we missed that the strbuf rev was still used in config_from() and now is
left empty. Lets fix this by also returning this string.
This means that now when reading .gitmodules from revisions, the error
messages also contain a reference to the blob they are from.

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.

hashcpy with null_sha1 as the source is equivalent to hashclr. In
addition to being simpler, using hashclr may give the compiler a chance
to optimize better. Convert instances of hashcpy with the source
argument of null_sha1 to hashclr.
This transformation was implemented using the following semantic patch:
@@
expression E1;
@@
-hashcpy(E1, null_sha1);
+hashclr(E1);

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.

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.

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.
