HADOOP-1534. [hbase] Memcache scanner fails if start key not present
* src/contrib/hbase/src/java/org/apache/hadoop/hbase/HMemcache.java
    (findFirstRow): Change compare from startsWith -- looking for
    an 'exact' match -- to instead use compareTo and if >= 0, then
    we are at first key.
* src/contrib/hbase/src/java/org/apache/hadoop/hbase/HRegionServer.java
    Add logging of problematic directory if server won't start because
    log file exists.
