Bernd Kuhls 6dbb40955f package/bento4: new package
Needed for the upcoming Nexus version of kodi-inputstream-adaptive,
the bundled version of bento4 was removed upstream:
70625e7670

Backported upstream commit to fix cmake install as patch 0001.

Added feature- and bugfix-patches from kodi, they were sent upstream:
https://github.com/axiomatic-systems/Bento4/issues/648

Build-tested using this defconfig:
