Update semantic table as part of identifier namespacing
Fix flaky test in TransactionIT closing socket to terminate transaction.

The test will now allow some time for the socket closing to propagate
network stacks and actually have an effect. It is a speculative fix.
Ignores empty property values from CSV input

by adding an additional CharSeeker#tryExtract returning whether or not a
value was extracted. Extractor#extract was changed to return whether or
not a values extracted for this occasion as well. The existing
CharSeeker#extract method throws exception if no value was extracted.
  Therefore skipping of empty values is consistent, whereas previously
non-primitive extractors could return null which was the only tell whether
or not a value was extracted.
Ability to control maximum number of processors used during import

also made terminology and doc around processor vs. thread in the context
of the importer more clear and consistent.

Add test and fix issue with concurrent drop and usage of legacy index.

Legacy index creation and deletion is not transactional, but its availability
was treated as such during the commit to store phase. If a particular index cannot
be found then it has been deliberately removed and thus any changes to it should
be directed to the bitbucket.
