BUG#13987 Cluster: Loss of data nodes can cause high CPU usage from ndb_mgmd

fix the actual problem (getting incomplete line of data), introduced with previous
improvement.

also add list sessions, get session and get session id to mgmapi to allow
the implementation of a test case for this exact problem.

21913: DATE_FORMAT() Crashes mysql server if I use it through mysql-connector-j driver.

Variable character_set_results can legally be NULL (for "no conversion.")
This could result in a NULL deref that crashed the server.  Fixed.

(Although ran some additional precursory tests to see whether I could break
anything else, but no breakage so far.)

The problem was due to a prior fix for BUG 9676, which limited
the rows stored in a temporary table to the LIMIT clause. This
optimization is not applicable to non-group queries with aggregate
functions. The fix disables the optimization in this case.
