Attached is my attempt to update Bluetooth into a source-built HPKG. Being the first time doing this, I'm uncertain if it's properly done.
This turns the OptionalPackage "Bluetooth" into a HPKG. Currently it is installed to /_packages_. The idea is for the bluetooth package to be installed on the boot medium, without being activated by default.
build/jam/packages/Bluetooth contains a TODO for implementing the development symlink for libbluetooth.so.
Untested beyond being able to build bluetooth.hpkg.
