FileSys: Updates backend code to use FileSys::Path and fixes binary path types.
core: Mark some hle functions as static

These functions are not referred to by their linkage name outside of the translation unit, so they can be marked as static.

Add a GUI logging channel.

Replace asserts with _dbg_assert_.
Viewport scaling and display density independence

The view is scaled to be as large as possible, without changing the aspect, within the bounds of the window.
On "retina" displays, or other displays where window units != pixels, the view should no longer draw incorrectly.
Fixup EmuWindow interface and implementations thereof.
EmuWindow: Add support for specifying minimal client area sizes.
EmuWindow: Add documentation.
EmuWindow: Remove window title getters/setters.

The window title is none of the emulation core's business. The GUI code is free to put whatever it wants there.
Providing properly thread-safe window title getters and setters is a mess anyway.
EmuWindow: Better document the purpose of OnMinimalClientAreaChangeRequest.
OpenGL Renderer: Cleanup viewport extent calculation.
MathUtil: Make Rectangle work with unsigned types.
EmuWindow: Add a TODO.

Implementing this function currently is not critical, as we don't perform any configuration changes, yet.

However, the interface is a good starting point for adding this functionality.
citra-qt: Small cleanup.
EmuWindow: Add some explicit documentation and set proper minimal client area size.
