Class-ify ui_out
This patch finalizes the C++ conversion of the ui-out subsystem, by turning the ui_out and ui_out_impl structures into a single class hierarchy. ui_out functions are turned into virtual methods of that new class, so as a result there are a lot of call sites to update. In the previous version of the patchset, there were separate ui_out and ui_out_impl classes, but it wasn't really useful and added boilerplate. In this version there is simply an ui_out base class that is extended for CLI, TUI and MI. It's a bit hard to maintain a ChangeLog for such a big patch, I did my best but I'm sure there are some missing or outdated info in there... gdb/ChangeLog: * ui-out.h (ui_out_begin, ui_out_end, ui_out_table_header, ui_out_table_body, ui_out_field_int, ui_out_field_fmt_int, ui_out_field_core_addr, ui_out_field_string, ui_out_field_stream, ui_out_field_fmt, ui_out_field_skip, ui_out_spaces, ui_out_text, ui_out_message, ui_out_wrap_hint, ui_out_flush, ui_out_test_flags, ui_out_query_field, ui_out_is_mi_like_p, ui_out_redirect): Remove, replace with a method in class ui_out.
