arm: Remove unnecessary booleans

We don't care about any of these.

This allows for easily movable and independent configuration and data directories, using standardized paths.

Services: Implemented Y2R_U::GetTransferEndEvent

rasterizer: Add support for RGBA4 framebuffer format.

Aero Porter was throwing an "Invalid Handle" fatal error without this.

Frontends, HID: Add New 3DS specific pad buttons, and stub the touch one.

Added information reporting from ThrowFatalError

GPU: Fixed RGBA8 as output format in a display transfer.

Verified with hwtests

This was RE'd from the errdisp applet.

GPU: Add support for more framebuffer formats in display transfers.

Rasterize with the correct color component order.

- Fixes a regression with #594.

Clean up unaligned 32-bit memory reads

GPU: Fixed the RGBA8 input format and RGB8 output format

Pica/VertexShader: Fixed LOOP with more than one iteration.

in Display Transfers, tested with hwtests.

Previously it wouldn't jump back to the start of the loop code once it reached the end of the block.
Fixes the texture problems in a lot of games.

Common: Change names containing “Dolphin” or “PPSSPP” to something more generic

Sweeping cleanup of Common

Convert a few C stdlib asserts to Citra's own asserts

Rasterizer: Fixed a warning in GetWrappedTexCoord.

Redeclaring the variable inside the switch was causing weird behavior.

core/video_core: Use in-place construction where possible

More PICA200 Emulation Fixes
