escape backslashes in ESCINFO[]. fixes #13855
[lang] update of core language files
[lang] update of skin.confluence language files
[lang] update of internal addon language files
fixed: the auto-addition of '..' when the list is empty did not show up on filtered lists
remove unnecessary toast + parent folder of empty lists after filtering - the '..' item is shown, so this won't be hit anyway
[lang] added langinfo.xml for new language: Amharic

[pvr] sync add-ons
[rbp/omxplayer] reverted e08fee30d1c9ca755ddb5c9833a19b8d1cbabff5 the PI firmware handles this now.
[fix] It appears that we were running out of Tls on windows. This changes the addon system so that a single one is created for the Interceptor functionality rather than one per window.
Add better error checking to the Windows ThreadLocal implementation.
