Pvr offset management

[nico1080]

As described on the CE forum, having a specific progress bar calculation to manage pvr offset
https://discourse.coreelec.org/t/graphical-front-panel-display/12932/191

This would need a section in setup.toml file where you define something like

use_PVR_offset = true 
PVR_start_offset= 600 #time (in second) that PVR record before the recorded program
PVR_stop_offset=600 #time (in second) that PVR record after the recorded program

Also these offsets could be used to create a special treatment on VideoPlayer.Time and VideoPlayer.Duration info labels to display correct time.

As these values could be negative, maybe a method to display negative value could be imagined (change of color, adding a '-' character, etc)

In the latest kodi_panel_display.py (for not-yet-released v1.27), I've modified where calc_progress() gets called.

That function call now occurs within either audio_screens() or video_screens() after any mode selection has occurred. The calc_progress() function now gets passed the selected layout name (as a string). So, one could replace the calc_progress() function.

However, per Post 202 on that same CoreELEC thread, the variability in PVR offset times that sounds possible seems like it reduces the utility of proceeding much further along this path. If you have uniform offsets, then you could now write your own calc_progress() substitute function, identical to the original except if the layout_name string is "V_PVR". If that layout is being used, the calculations can then be modified as desired.

The change to kodi_panel_display.py is in commit 4dcda63.

This solution work Ok.

I added my offset with this function: nico1080@b876444
