polkit-qt-1: Qt 5 support

polkit-qt-1 is upgraded to the latest version, which supports Qt 5. The
attributes are also renamed to differentiate the Qt 4 and Qt 5
branches. The prior naming scheme differentiated between polkit-qt-1 and
polkit-qt, but we no longer package the latter.
phonon: upgrade to 4.8.1

This version adds Qt 5 support.
phonon-backend-gstreamer: add Qt 5 support
phonon-backend-vlc: add Qt 5 support

Merge branch 'qt5-support' into staging

Update Qt 5 to version 5.3.2. Drop the 5.2 branch. Update several
libraries to their latest versions to take advantage of Qt 5
support. The last point will cause a KDE 4 rebuild.
Merge branch 'qt5-tzdir' into staging

Fixes a long-standing bug with Qt 5 and timezones on NixOS.
Adds libltc

Linear (or Longitudinal) Timecode (LTC) is an encoding of timecode data
as a Manchester-Biphase encoded audio signal. The audio signal is
commonly recorded on a VTR track or other storage media.

libltc provides functionality to encode and decode LTC from/to timecode,
including SMPTE date support.

libltc is the successor of libltcsmpte.
