[pvr] make all livetv views available to the user earlier (as soon as channels are fetched from the backend and before epg is loaded from the db) by changing the pvr/epg manager startup logic
Revert "[epg] fixed - epg load/update was interrupted when the pvr manager imports channels, leading to delays and channel ids gone missing in certain situations"

This reverts commit bdf8842d543fae54067c4dd453bded8474e1044f.

xbmc.sh: read Release info from os-release
If /etc/os-release exists, read the info from there

xbmc.sh: extract core dump from systemd's journal
On systemd systems, core dumps are - by default - written to systemd's
logging system, the journal. The print_crash_report function only
searches certain directories for the core dump, but would never find
it in the journal, resulting in an empty stack trace in the crash log.
As a workaround, simply extract the last core dump caused by xbmc.bin
to "core" where the single_stacktrace function will find it.
If the system is configured to not dump cores into the journal,
systemd-coredumpctl will simply fail silently.

[OverlayRenderGL] Fix corrupt pixels in graphical subs

On Pi you can see a corrupt line of pixels on bottom and right edges of subtitle bounding box.
This is due to using a subregion of a texture (due to the power of two rounding) and not ensuring
the texture coordinates are inside the valid pixels.

The easy solution is to use NPOT when available (always on GLES) and then the clamping works
(as well as saving memory).

updated addon helpers

in particular, we now handle buildsystems which output several add-ons
properly. real life case; screensavers.rsxs
[WIN32] added a xbmc-config.cmake.win32 for windows
[WIN32] added xbmc_find_path to find paths recursively
[WIN32] removed prepare_addon_environment(). this is done in the prepare-env step now.
move to addon helpers. fits better and avoids duplication for win32
[cmake] add lto support again
[cmake] fix tgz package and set zip as default cpack_generator
