  Fix git_submodule_sync and add new config helper
  
  This fixes `git_submodule_sync` to correctly update the remote URL
  of the default branch of the submodule along with the URL in the
  parent repository config (i.e. match core Git's behavior).
  
  Also move some useful helper logic from the submodule code into
  a shared config API `git_config__update_entry` that can either set
  or delete an entry with constraints like not overwriting or not
  creating a new entry.  I used that helper to update a couple other
  places in the code.
