Return back Percona's "innodb_stats_method=nulls_ignored" algorithm.

Related Launchpad bug #892405
Related MySQL bug http://bugs.mysql.com/bug.php?id=63320

I added new value "nulls_ignored_exact" for variable innodb_stats_method.

Current upsteam "nulls_ignored" algorithm calculate not_null values on every estimated (random) page, and after that try to approximates total value count.
Unfortunately, this algorithm works incorrectly on mostly null indexes (see MySQL Bug #63320).

Percona'a algorithm excludes from estimation pages with nulls, calculates the count of different values and approximates total value count.
This algorithm works correctly on mostly null indexes, but has limitation - it works correctly just on one-column-key indexes. On compound-keys algorithm can works incorrectly (I didn't test this).
Unfortunately, I can't imagine now how to discard this limitation.

Merge Alexey's commit:
    Bug #872754: Annotate rows events on slave doesnt' work without slave's binlog

    The problem was that Read_Master_Log_Pos was not calculated correctly
    when events were being skipped on the master (i.e. Annotate_Rows_Events
    when either replicate-annotate-rows-events or log-slave-updates were OFF).

    Fixed by changing the calculation so that master_log_pos is read from
    the event's header if it's available. Otherwise, proceed with the
    default logic.
