Extend the subtitle delays to upto 20 seconds

As it seems to be required on some services.
I hope this will be enough
Change of timeshift stop button functionality

Switching to live tv with stop button disables timeshift. This
is undesired if automatic timeshift start is active. This patch
uses built-in c++ switchToLive function to switch to live point
without disabling timeshift.

InfoBarGenerics: Only show pvr state when infobar is shown
Enable InfoBarInstantRecord menu in MoviePlayer
Use class name to determine if we are in the standard Infobar
Show also the instant recordings when in movie infobar
When closing standby screen also remove record_event

When the RecordTimerEntry Quitmainloop is activated while the box is in
standby when coming out if standby the notification is removed, but there
is still a record_event left in Navigation that still may shut down the
box after a recording event ends which is set as an auto recording.

Now also only the notification and the record_event is removed as the
RecordTimerEntry Quitmainloop is really activated.
