[tor-commits] [tor/master] Replace add_temp_log() with add_default_log().

commit 3a73f6612aad051e0d9a9228a136e06720748c16

    Replace add_temp_log() with add_default_log().
    
    We used to have this function so that we could mark our initial
    log-to-stdout as specifically temporary so that we would delete it
    once regular logs were configured.  But it's no longer necessary to
    mark these logs as temporary, since we now use a mark-and-sweep
    process to ensure that _all_ not-configured logs are closed when we
    change our configuration.
    
    Instead, this function will be the basis of a refactoring in how we
    handle default logs.
