Augustin Cavalier cbfbbf6d4d Change BObjectList to take "owning" as a template parameter and adjust all consumers.
Since BObjectList is a template class, this only breaks ABI where
BObjectList was exposed in public methods, and even then it's only
a name mangling break and we should be able to add compatibility
methods if necessary.

(The old "bool owning" member variable is left intact for ABI
compatibility, for the moment, though it's otherwise unused now.)

Tracker's PoseList is the only remaining type that has a "bool owning"
switch in the constructor rather than template parameters.

This should significantly improve the output of static code analysis
tools that previously detected list operations as causing use-after-frees
and double-frees, as well as make code maintenance easier by making it
easier to determine what list owns (or does not own) an object.
It should also be a minor performance optimization, since the branches
for calls to delete/free should now be optimized out altogether.

Still boots to desktop and Tracker, Deskbar, Debugger all tested
and verified as working.
