This had been forgotten in df81fa11.

Fixes #1711.

Replace std::map with std::array for graphics event breakpoints, and allow the compiler to inline. Saves 1%+ in vertex heavy situations.

This also means : we have only one config file, now

Add error popup when citra initialization failed

citra: Remove GLFW, Add SDL2

FindSDL2: Do not CACHE SDL2_* variables if library is not found

EmuWindow_SDL2: Set minimal client area at initialisation time

EmuWindow_SDL2: Corrections

EmuWindow_SDL2: Fix no decorations on startup on OS X

cmake: windows_copy_files

This commit:
* Adds a new subproject, audio_core.
* Defines structures that exist in DSP shared memory.
* Hooks up various other parts of the emulator into audio core.

This sets the foundation for a later HLE DSP implementation.

Implement confirmation in a specific function
Fix typos and coding style

Coding convention

Not much thought went into that one...

ScanDirectoryTreeAndCallback, before this change, coupled error/return
codes and actual return values (number of entries found). This caused
confusion and difficulty interpreting the precise way the function
worked.

Supersedes, and closes #1255.

to support non-latin characters

Before this changing these settings from the GUI would apply the
settings, but they were reseted to the default values when exiting
citra.

Previously the Mac app didn't have any icon.

The LOG_* function itself already appends one.

Properly hides the game list upon toggling from external
window mode to single window mode. Previously, both the game
list and the render window would have been shown at the same
time upon toggling.

The OS will render the widgets using the system screen DPI (instead of
being locked at @1x resolution).

This has no impact on the existing high-DPI rendering code in Citra,
which means that the resolution of the emulated content is increased
to the real number of pixels, as on other platforms.

Instead of letting CMake re-generate an automatic Info.plist file on
every build, use our own. This allows greater control on the application
bundle settings.
