C++/JNI: helper_base.hpp/cxx: Rework raise_java_exception(..) and rethrow_and_raise_java_exception[->_impl](..) ..
Commit 5cfe7e13c4dbf07360d928e421050de5e00684a1 intention was noble, however, 'inline' is not guaranteed and doesn't work here. I.e. the desired inline reduction with automatic elision and using __FILE__ and __LINE__ macros is not supported. Instead, move the functions back to helper_base.cxx and add paramter for __FILE__ and __LINE__ to be passed by the only caller macro 'rethrow_and_raise_java_exception(E)'. The latter simply explodes to 'rethrow_and_raise_java_exception_impl((E), __FILE__, __LINE__)', which serves the purposed of having exposed the file and line position where the exceotion got caught. Also support api/tinyb/BluetoothException, rendering commit 3139f93409cac61ba5b80caf506375d94eff8778 valid, i.e. use rethrow_and_raise_java_exception(..) in the tinyb C++/JNI code instead of exploded exception case blocks.
