If axes!=0 and buttons==0 and hats==0, then the build fails because some
button-related functionality is missing. Move the joystick axis->button
bridge into a conditional to exclude it in this case.

The minimum supported compiler versions now provide a depth-efficient
implementation of std::make_index_sequence, which removes the last
reason to carry a private implementation. In the case of clang, it
appears to have a special compiler intrinsic used to implement its
std::make_index_sequence.
Switch to the compiler-provided version for both gcc and clang.
Each axis can act as two buttons in both ways.
For example, a player might map slide left and slide right to J1 -A1 and J1 +A1 as button presses instead of the slide L/R axis.
This is mostly to fix XBox 360 Controller Left and Right triggers. But it can work on every axis if the player wishes to bind them.
The subcanvas is positioned based on the dimensions of the containing
window, so it must be repositioned if the outer window is resized.

gcc-7 needs an additional cf_assert to inform it that e.idx is
constrained. Without this, it assumes e.idx could have any positive
value, then issues a fatal warning when INT_MAX does not fit in the
provided buffer.

Add configuration file entries for number of chips, bank index, and
whether to use ADL MIDI. Currently, there is no GUI for this.
Interested users must enable it via direct configuration file editing.
A menu interface will come later.

Add macro cf_assert ("control flow" assert) to hint to gcc that certain
conditions are impossible. Use it to avoid generating range checks for
situations that never happen. If the event did happen, the only
consequence would be truncated UI text, rather than a correctness
problem.
gcc-7 allows `constexpr auto X = std::initializer_list<unsigned>{A1, A2,
...};`. gcc-8 rejects it:
```
common/arch/sdl/key.cpp:583:105: error: 'const std::initializer_list<const SDL_Scancode>{((const SDL_Scancode*)(&<anonymous>)), 3}' is not a constant expression
constexpr auto sticky_keys = {SDL_SCANCODE_CAPSLOCK, SDL_SCANCODE_SCROLLLOCK, SDL_SCANCODE_NUMLOCKCLEAR};
```
Switch to a macro and a fully anonymous list, which is accepted by both
versions.
Fixes: f491059ed7 ("Enable building with SDL2")
This commit enables Rebirth to build with SDL2, but the result is not
perfect.
- SDL2 removed some sticky key support. Rebirth may behave differently
now in this area.
- SDL2 removed some key-repeat related support. Rebirth may behave
differently now in this area.
- SDL2 gained the ability to make a window fullscreen by sizing it to
the desktop instead of by changing the desktop resolution. Rebirth
uses this, and it mostly works.
- Resizing while in the automap does not notify the automap code, so
the view is wrong until the player switches out of automap mode and
back in.
- SDL2 changed how to enumerate available resolutions. Since
fitting the window to the desktop is generally more useful than
fitting the desktop to the window, I chose to drop support for
enumerating resolutions instead of porting to the new API. Users can
now enter an arbitrary window dimension and Rebirth will make an
attempt to use it.
- It might be useful to cap the window dimension at the desktop
dimension, but that is not done yet.
- Entering fullscreen mode through the Controls->Graphics submenu
failed to notify the relevant subsystems, causing the rendered
content not to rescale. For now, compile out the option to toggle
full screen through that menu. Toggling through Alt+Enter works
properly.
Despite these quirks, this is a substantial improvement over the prior
commit, where SDL2 cannot be used at all. The remaining issues can be
resolved in future work.

Various points in the game code call `hide_menus()`, then later use
`show_menus()` to reverse the effect. If the forcibly hidden window is
deleted before `show_menus()` is called, the attempt to show it would
write to freed memory. Add a hook to forget those windows when they are
deleted, so that `show_menus()` does not try to make them visible later.
Add 'track' method to dcx::window, which takes a bool and will set it to 'false' when the window closes. Use for newmenu_do2 and simpler newmenu_do's, since there's the possibility of another window without its own polling loop opening on top - meaning window_event_result::deleted would be returned for that window, not the one we're polling on.
This will allow checking for window_event_result::deleted, instead of relying on window_exists, which could return a false positive if a new window was allocated with the same pointer value as the deleted one.
