	HIST_LOG_BUCKETS.
	(_stp_pmap_new_hstat_log): Ditto.
	(_stp_map_new_hstat_linear): Call _stp_stat_calc_buckets().
	(_stp_pmap_new_hstat_linear): Ditto.

	* stat.h (STP_MAX_BUCKETS): Define..
	(HIST_LOG_BUCKETS): Define.

	* stat.c (_stp_stat_init): Call _stp_stat_calc_buckets().

	* stat-common.c (_stp_stat_calc_buckets): New function. Common
	bucket calculation and error reporting code.
	(_stp_bucket_to_val): New function.
	(_stp_val_to_bucket): Renamed and now handles negative numbers.
	(_stp_stat_print_histogram): Handle negative values in log histograms.
	(__stp_stat_add): Cleanup..
