Bence Ferdinandy Oct. 19, 2024, 10:53 p.m. UTC 
If the user has remote/HEAD set already and it looks like it has changed
on the server, then print a message, otherwise set it if we can.
Silently pass if the user already has the same remote/HEAD set as
reported by the server or if we encounter any errors along the way.

Notes:
    v3: - does not rely on remote set-head anymore so it only authenticates
        once
        - uses the new REF_CREATE_ONLY to atomically check if the ref exists
          and only write it if it doesn't
        - in all other cases the maximum it does is print a warning
    
    v4: - instead of the discarded REF_CREATE_ONLY, it uses the existing,
          but updated transaction api to request a silent create only
        - it now uses the atomic before_target to determine reporting
        - refactored for legibility
    
    v5: - instead of printing a not too useful message, it now fails
          silently, this in line with the objective to only set up
          remote/HEAD automatically if the right thing is trivial, for
          everything else there is remote set-head
        - fixed all failing tests
        - added two new tests, one for checking if remote/HEAD is set to the
          correct one, and one to test that we do not override remote/HEAD
          if it has changed on the server from what we have locally
    
    v6: - fixed style issues and unintended extra empty line
        - updated function call with bool to int from previous patch's
          change
        - removed calls to error(...) inherited from builtin/remote.c so we
          actually fail silently
        - set the test for remote set-head --auto to the correct value here,
          which was previously erronously set in the remote set-head patch
    
    v7: - no change
    
    v8: - changed logmsg in call to refs_update_symref from "remote
          set-head" to "fetch"
    
    v9: - follow through with refs_update_symref_extended
        - fix test errors uncovered by the new patch
