* symfile-mem.c (do_target_read_memory): New function. (symbol_file_add_from_memory): Pass do_target_read_memory to bfd_elf_bfd_from_remote_memory. * corefile.c (write_memory): Update, make a copy of the read-only buffer. * target.c (target_read_memory): Update. (target_write_memory): Update, make a copy of the read-only buffer. * gdbcore.h (write_memory): Change buffer type to bfd_byte, make const. * target.h (target_read_memory, target_write_memory): Change buffer type to bfd_byte; for write_memory, make it const.
