Currently, Python code can use event registries to detect when gdb loads a new objfile, and when gdb clears the objfile list. However, there's no way to detect the removal of an objfile, say when the inferior calls dlclose. This patch adds a gdb.free_objfile event registry and arranges for an event to be emitted in this case.
