Added debug print to place where changing DCB state fails.
Bug #399, http://bugs.skysql.com/show_bug.cgi?id=399
Corrected the length variable including length of timestampt string which doesn't include terminating null.
Made a quick fix to server/core/test/testhash.c. In makefile there is one call for multiple tests and so it makes sense to check return value of the test program.
Initialized argument pointer values with zeroes in hashtable_get_stats.
