Stefan Beller	f793b895fd	submodule-config: allow submodule_free to handle arbitrary repositories At some point we may want to rename the function so that it describes what it actually does as 'submodule_free' doesn't quite describe that this clears a repository's submodule cache. But that's beyond the scope of this series. While at it remove the extern key word from its declaration.

Robert P. J. Day	5aea9fe6cc	Correct mispellings of ".gitmodule" to ".gitmodules" There are a small number of misspellings, ".gitmodule", scattered throughout the code base, correct them ... no apparent functional changes.

Stefan Beller	73c293bb6c	submodule-config: rename commit_sha1 to treeish_name It is also possible to pass in any treeish name to lookup a submodule config. Make it clear by naming the variables accordingly. Looking up a submodule config by tree hash will come in handy in a later patch.

Heiko Voigt	851e18c385	submodule: use new config API for worktree configurations 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.

Heiko Voigt	959b5455d0	submodule: implement a config API for lookup of .gitmodules values 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.
