post-review fixups - magnus suggested creating dynstr_trunc instead of doing
it manually.

post-review fixes.

Magnus suggested use of DYNAMIC_STRING instead of futzing with c strings.
also making usage of TABLEs clearer in store_schema_partitions_record.

Post review fix:
Magnus suggested making sure that new mysqldump still worked flawlessly
with old servers.

Update mysqldump to dump the needed tablespaces to create the tables
for either the dbs or tables we're dumping.

With --all-tablespaces, we still dump everything.

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.
