Get rid of the global "base_target" and use "find_target_beneath"
to find the underlying target. * dec-thread.c (base_target): Delete. (enable_dec_thread): Remove assignement to base_target. (dec_thread_detach, dec_thread_wait, dec_thread_wait) (dec_thread_fetch_registers, dec_thread_store_registers) (dec_thread_mourn_inferior, dec_thread_pid_to_str): Update the function profile if necessary. Use find_target_beneath to call the same method but from the underlying target, removing the need for "base_target". * dec-thread.c (dec_thread_get_regsets, dec_thread_set_regsets): Fix a copy/paste error in a few debug traces... * solib-osf.c (init_so): Use a simpler method for computing the size of lm_info structure. This also gets rid of warning emitted by the compiler.
