The tls_nodelete state should apply to load_group not isolated soinfo. This actually also means that multiple soinfos may have tls_counter on their dso_handles. This change replaces TLS_NODELETE flag with secondary counter. Note that access to the secondary counter (located inside soinfo) is pretty expensive because it requires soinfo lookup by dso_handle whereas dso_handle counter is much faster. This is why it is updated only when dso_handle counter starts or hits 0. Bug: http://b/80278285 Test: bionic-unit-tests --gtest_filter=dl* Change-Id: I535583f6714e45fa2a7eaf7bb3126da20ee7cba9
