Main code, examples, tests and docs updated. Method: 1. Mass find+replace "QtMultimedia::" -> "QMultimedia::" 2. Hand-modified declaration in qtmedianamespace.h/cpp For consistency (with minimal disruption), namespaces with a "Qt" prefix will be renamed. Part of the Header Consistency Project (http://lists.qt-project.org/pipermail/development/2012-October/007570.html) Change-Id: I1fbc43a1aa91d996aa61869fcd8d05186bf7cf6d Reviewed-by: Lars Knoll <lars.knoll@digia.com> Reviewed-by: Stephen Kelly <stephen.kelly@kdab.com>
