* solist.h (struct so_list): Remove from_tty. * solib.c (solib_bfd_open): Return NULL if we failed to open a BFD. (solib_map_sections): Take so_list argument. Return 0 if we failed to open a BFD. Add target sections here. (symbol_add_stub): Delete. (solib_read_symbols): Inline symbol_add_stub. Use current flags, not from_tty copied from the so_list. Don't warn a second time for a missing library. (update_solib_list): Don't save from_tty. Use TRY_CATCH. Do not add to the section table here. Print out a single warning for all missing libraries. * bsd-uthread.c (bsd_uthread_solib_loaded): Always pass 0 for flags.
