We still do not have any users of the 'frontend' interface, let's right a wrong and rename it to 'transport' as it makes more sense. Renames android_log_set_frontend, android_log_get_frontend and include/log/log_frontend.h. SideEffects: None Test: gTest liblog-unit-tests Bug: 27405083 Change-Id: I7c1c0f3dfdc7cf047285403e306edbd16ad1324d
