Commit 57b3ce246a932ce3798e40ea7e6e23c17346c9f0 in asterixdb's branch refs/heads/master from
Ali Alsuliman
[ https://gitbox.apache.org/repos/asf?p=asterixdb.git;h=57b3ce2 ]

[ASTERIXDB-2791][IDX] Set null flags when writing an index entry

- user model changes: no
- storage format changes: no
- interface changes: yes

Details:
When writing an index entry, set the corresponding null flags
for keys that are considered null. When reading an index entry,
examine the null flags to read the index entry properly.

 - add INullIntrospector interface that can be used by Hyracks
   to know if a key is null or not.

across all index types. For a composite secondary index, it should be possible to accept partial
nulls and missings keys.
