Add a limit to the starttime of 24 hours to minimize the index sequence scans on the program table
Add channel callsign to OSD

After adding a HDHR Prime to my system it became apparent that the OSD did not display the channel callsign which made browsing channels very difficult. This seemed to work well for me. The SD theme could probably use this too but the widget placement would need to be tweaked.
Allow for /usr/X11R6 directory or symlink

If a system has a /usr/X11R6 directory or symlink, the .pro files do not move the /usr/X11R6 include to the end, causing build failures. This commit fixes libmyth.pro to relocate this directory, as well as /usr/local and /usr/local/include.

While here, add the missing assignment of POSTINC back to INCLUDEPATH.
Support /usr/X11R6 directory or symlink

When systems have a symlink or directory at /usr/X11R6, this gets included early in the -I chain. Move it to the end with /usr/include and /usr/local/include
Move $$POSTINC append to the end.

Testing showed that the existing appending of POSTINC was not late enough. Move it right to the end. In particular, DVD stuff and Blueray stuff includes were being hidden by /usr/X11R6/include.
Add code to move standard includes to end.

On certain systems, standard includes like /usr/include and /usr/local/include (and /usr/X11R6/include) end up before the includes for the bundled libraries. This moves all of them to the end.
Add code to move standard includes to end.

This place also needs this, pulling in the systems own dvd player libs' include files
Add draft HEVC descriptor support
move implementation of the unit tests into the cpp file

MythUIImage: extend the random image feature to reload if a delay is used

If the <filename> is set to a directory and the <delay> is set to a value > 0
then keep reloading a random image from the directory after <delay>
milliseconds has passed.

For example this will display a random image from the themes 'background'
directory changing the image every minute (60000ms) :-

<imagetype name="background">
    <area>0,0,1280,720</area>
    <filename>backgrounds/</filename>
    <delay>60000</delay>
</imagetype>
