Introduce new_bfd_ref
This introduces a helper function, new_bfd_ref, that calls gdb_bfd_ref and returns a gdb_bfd_ref_ptr. Then it updates several places to use this. ChangeLog 2017-10-20 Tom Tromey <tom@tromey.com> * exec.c (exec_file_attach): Use new_bfd_ref. * symfile-mem.c (symbol_file_add_from_memory): Use new_bfd_ref. * gdb_bfd.c (gdb_bfd_open, gdb_bfd_fopen, gdb_bfd_openr) (gdb_bfd_openw, gdb_bfd_openr_iovec, gdb_bfd_fdopenr): Use new_bfd_ref. * gdb_bfd.h (new_bfd_ref): New function.
