Make symfile_add_flags and objfile->flags strongly typed

This makes these flag types be "enum flag" types.  The benefit is
making use of C++'s stronger typing -- mixing the flags types by
mistake errors at compile time.

This caught one old bug in symbol_file_add_main_1 already, fixed by
this patch as well:

  @@ -1318,7 +1326,7 @@ symbol_file_add_main_1 (const char *args, int from_tty, int flags)
	what is frameless.  */
     reinit_frame_cache ();

  -  if ((flags & SYMFILE_NO_READ) == 0)
  +  if ((add_flags & SYMFILE_NO_READ) == 0)
       set_initial_language ();
   }

Above, "flags" are objfile flags, not symfile_add_flags.  So that was
actually checking for "flag & OBJF_PSYMTABS_READ", which has the same
value as SYMFILE_NO_READ...

I moved the flags definitions to separate files to break circular
dependencies.

Built with --enable-targets=all and tested on x86-64 Fedora 23.
