[tor-commits] [tor/master] Turn on directory request statistics by default.

commit 9dfb8845229ed66efb2222b8dec6c624f8adb7c9
Author: Karsten Loesing <karsten.loesing@xxxxxxx>

    Turn on directory request statistics by default.
    
    Change the default values for collecting directory request statistics and
    inlcuding them in extra-info descriptors to 1.
    
    Don't break if we are configured to collect directory request or entry
    statistics and don't have a GeoIP database. Instead, print out a notice
    and skip initializing the affected statistics code.
    
    This is the cherry-picked 499661524b0a572303087af721325608dd91f7ce.
