Ref #5555

Closes #4052

Previously if there were any “pin” updates then that would block all non-pin updates until the pin one was merged. However, this doesn’t make sense if the other PR is for an unrelated dependency.

Closes https://github.com/renovatebot/config-help/issues/64

Rewrite of dependency extraction, particularly for npm. Paves way for easier addition of new package managers.

Closes #1882

If a lockFileMaintenance branch returns no updated lockfiles then we should delete it.

Closes #1655

Adds a new feature to limit the number of concurrent branches/PRs to have open at any one time. Defaults to 0 (disabled), set it to a positive integer to enforce that limit.

Adds a feature to enforce an hourly limit on PR creations.

Closes #1363

This reverts commit eb579ff3.

Closes #1299

Repository logic code has been rearranged for better logic and file separation.
