The libretro core is the frontend, and the headless tools are the test and
debugging hosts. The Windows, UWP, Android, iOS, macOS and SDL apps, the UI
framework and imgui go, along with what only they used: the Win32 debugger
hooks (g_frameMutex, the shutdown lock), JNI thread attachment, the Android
text drawer, RAIntegration, Discord, recent files, game installs, tilt input,
the audio resamplers, the control mapper, memstick moving and the remote ISO
and upload server modes. The web server keeps the debugger. The MSVC, Gradle
and ndk-build projects go too.
VulkanGraphicsContext::InitSurface() threw away VulkanContext::InitSurface()'s
VkResult and carried on, so a failed surface init surfaced as
_dbg_assert_(GetAvailablePresentModes().size() > 0) in the VKContext
constructor rather than as a graphics error with the usual backend fallback.
The vkCreate*SurfaceKHR failure path in ReinitSurface() didn't log anything
either, so the assert was the only trace of it.
Now ReinitSurface() logs and sets init_error_ for all three ways it can bail
(surface creation, ChooseQueue, present mode enumeration), InitSurface()
checks the result, and MainThreadFunc() passes the message back out instead of
writing it to a local it then drops - Windows/main.cpp was reporting
"Failed to initialize main thread function." to the user.
Also deletes the Application on that failure path, which was leaked.
