Separate generation of a dirreq-stats string from writing it to disk.

This patch separates the generation of a dirreq-stats string from
actually writing it to disk.  The new geoip_format_dirreq_stats()
generates a dirreq-stats string that geoip_dirreq_stats_write() writes
to disk.  All the state changing (e.g., resetting the dirreq-stats
history and initializing the next measurement interval) takes place in
geoip_dirreq_stats_write().  That allows us to finally test the
dirreq-stats code better.
