In SQLA 0.9 there is now a native .quote attribute on many objects.
Conditionally use this instead of the old method if the attribute
exists, to remove deprecation messages (and prepare for when the
other way will be fully removed).

Since ibm_db_sa is not part of sqlalchemy, we need to handle the
conditional import of the module in visitor.py so we don't get an
ImportError if ibm_db_sa is not available.

Remove all trailing spaces and tabs in every file in the project.
People have editors configured to do this, which causes them to
accidentally make little whitespace changes in unrelated commits,
which makes those commits harder to review. Better to fix them all
at once.

2. The dialect registration with the visitor.
3. Code to parse the engine name in version.py.
4. A new dependency on ibm_db_sa in test-requirements.txt.
5. A connection string in test_db.cfg for ibm_db_sa.
