stack updated HBASE-975:
------------------------

    Attachment: 975-v4.patch

This patch is basically working.  Uses cached start and end keys to avoid seeking.  Also moves
all of the MapFile subclasses -- bloom, half and hbase -- out into io package.

> Keeping a MapFile's start and end key in cache would save us some seeks, see if it can
be done.
