bitbake: gitsm.py: Refactor the functions and simplify the class
The update_submodules and unpack_submodules functions were nearly indentical, so we made a common function where the different behavior could be passed in by the download and unpack users. The new function is process_submodules. Moved the parse_gitmodules function under the new process_submodules, since there are no external callers. Refactor the file relative path processing to the URL translation code. We also add a warning to the translation if a relative ssh URL has been detected. Since this can cause a problem. In the case of a relative URL that does not work after being translated, it should be possible to use the MIRROR functions to manual translate the generated relative URL into one that works properly. Remove 'git config' processing on download contents. It turns out this is not necessary since all of the later components work using the git fetcher. Limit the 'git submodule update' call to only when unpacking a non-bare repository. Submodules are always loaded as bare, so this prevents intermediate unpacks from being attempted. Finally, the test cases were updated and the new commit ids in the test repository were updates as well.
