xbmc.sh: read Release info from os-release
If /etc/os-release exists, read the info from there
instead of relying on lsb_release.

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.

[release] version bump to 13.0 alpha8 as we start new merge window.
Fixed missing error message in debug log, "Unable to load '.so file', reason: (null)"

Error message comes from dlerror() in xbmc/cores/DllLoader/SoLoader.cpp when CAndroidDyload::Open() fails. However, dlerror() is also called inside CAndroidDyload::Open(). This causes the second, outer dlerror() to return NULL, because (from the documentation) "dlerror() returns NULL if no errors have occurred since initialization or since it was last called".
Remove the Xp specific threading code.
Reapply @elupus 's fix to the Condition variable for windows. This also handles the case where the CritSec used for the ConditionVariable is entered more than once; something the native windows calls don't allow.

SoftAE: Fix A/V sync issues caused by wrong buffer time calculation

CSoftAE::GetDelay(), CSoftAE::GetCacheTime(), and
CSoftAE::GetCacheTotal() assume in their calculations that m_buffer
contains frames that have sink/encoder frame size. However, m_buffer
actually contains frames in the format received from CSoftAEStream.

This causes varying levels of A/V de-sync depending on other conditions.
On my Linux system I encounter this always when using using HDMI audio
and having the display refresh rate set at 24Hz.

Fix those functions to use the correct frame size.
