filemerge: move decorator definition for internal merge tools to registrar This patch also adds extra loading entry for internal merge tools to extensions.py, for similarity to other decorators defined in registrar.py. This patch uses "internalmerge" for decorator class name, instead of original "internaltool", because the latter is too generic. BTW, after this patch, 4-spaces indentation is added to the 1st line of internal merge tool description docstring, and this may make already translated entries in *.po fuzzy. Even though this indentation is required for "definition list" in reST syntax, absence of it has been overlooked, because help.makeitemsdoc() forcibly inserts it at generation of online help. But this forcible insertion causes formatting issue (I'll send another patch series for this). Therefore, this additional indentation should be reasonable.

releasenotes: add similarity check function to compare incoming notes It is possible that the incoming note fragments have some similar content as the existing release notes. In case of a bug fix, we match for issueNNNN in the existing notes. For other general cases, it makes use of fuzzywuzzy library to get a similarity score. If the score is above a certain threshold, we ignore the fragment, otherwise add it. But the score might be misleading for small commit messages. So, it uses similarity function only if the length of string (in words) is above a certain value. The patch adds tests related to its usage. But it needs improvement in the sense of combining incoming notes. We can use interactive mode for adding notes. Maybe we can do this if similarity is under a certain range.

releasenotes: add import check for fuzzywuzzy This patch adds the has_fuzzywuzzy for import check of external dependency fuzzywuzzy.
