Subject: Add support for change-tracking containers

ODB now supports "smart" ordered containers. Such containers get extra
functions for updating and deleting individual elements. Based on this
functionality implement two change-tracking containers: odb::vector
(equivalent to std::vector) and QOdbList (equivalent to QList). New
tests: common/container/change-tracking and qt/common/container/change-
tracking.
