mythtv-core @0.28: Build error on Mojave

[y-lee (Yeechang Lee)]

After upgrading to MacOS 10.14 Mojave from 10.13 High Sierra and migrating Macports, I could not build mythtv-core.26 which I'd been maintaining locally after being marked obsolete in the Macports tree. When building mythtv-core.28, I see

:info:build tv_play.cpp:216:34: error: reference member 'm_menu' binds to a temporary object whose lifetime would be shorter than the lifetime of the constructed object                                                                        
:info:build     MenuNodeTuple(void) : m_menu(MenuBase()) {}

I also ran into this when compiling v30. I changed the code at line 219 of tv_play.cpp to:

const MenuBase m_menu;

and it then compiled.
