Bugs Fixed

NDB Cluster APIs: Incorrect results, usually an empty result set, were returned when setBound() was used to specify a NULL bound. This issue appears to have been caused by a problem in gcc, limited to cases using the old version of this method (which does not employ NdbRecord), and is fixed by rewriting the problematic internal logic in the old implementation. (Bug #89468, Bug #27461752)
Queries using very large lists with IN were not handled correctly, which could lead to data node failures. (Bug #27397802)
References: See also: Bug #28728603.
ndb_restore --print-data --hex did not print trailing 0s of LONGVARBINARY values. (Bug #65560, Bug #14198580)
