databases/py-sqlalchemy10: Drop nop MYSQL option

It never did anything.  Prepare for D19553: Options helpers set
after bsd.port.options.mk are ineffective.

Use PY_FLAVOR for dependencies.

FLAVOR is the current port's flavor, it should not be used outside of
this scope.

Update CONFLICTS_INSTALL

Approved by:	portmgr (blanket)

Convert Python ports to FLAVORS.

  Ports using USE_PYTHON=distutils are now flavored.  They will
  automatically get flavors (py27, py34, py35, py36) depending on what
  versions they support.

  There is also a USE_PYTHON=flavors for ports that do not use distutils
  but need FLAVORS to be set.  A USE_PYTHON=noflavors can be set if
  using distutils but flavors are not wanted.

  A new USE_PYTHON=optsuffix that will add PYTHON_PKGNAMESUFFIX has been
  added to cope with Python ports that did not have the Python
  PKGNAMEPREFIX but are flavored.

  USES=python now also exports a PY_FLAVOR variable that contains the

Invoke pytest from within desired python version

When testing a port for a non-default python py.test may fail to find
dependencies for default version because they weren't built e.g.,

$ make test PYTHON_VERSION=python3.5 -C devel/py-apscheduler

Reorganise and modernise the py-sqlalchemy ports.

 - Introduce new ports for the sqlalchemy 0.9 and 1.0 release branches.
 - Deprecate the ports for the 0.6 and 0.7 release branches, as these
   have been declared EoL and are no longer supported by upstream.
 - Update to the latest available version in each branch.
