Ensures that -Wall is always active as a compilation flag.

Port citra-emu/citra#4215: "travis: Use Ninja for Travis builds"

Unintentionally introduced in 552d5071

Port citra-emu/citra#3839: "travis: use prebuilt image"

gl_shader_disk_cache: Improve precompiled shader cache generation speed and size

shader_ir: Miscellaneous fixes

kernel/vm_manager: Remove usages of global system accessors

video_core: Silent -Wswitch warnings

Corrections on Half Float operations: HADD2 HMUL2 and HFMA2

kernel/svc: Clean up wait synchronization related functionality

Allow picking a Compatibility Profile for OpenGL.

Port citra-emu/citra#4748: "Launch directly in Mac without terminal"

applets: Add AppletManager and implement PhotoViewer and Error applets

CMakeLists: Ensure we specify Unicode as the codepage on Windows

gl_state: Fix samplers memory corruption

Fix flipping on some games by applying Y direction register

gl_shader_decompiler: Disable variable AOFFI on unsupported devices

service/audctl: Implement GetTargetVolumeMin() and GetTargetVolumeMax()

Support compressed formats on linear textures.

GPU Manager: Implement ReadBlockUnsafe and WriteBlockUnsafe

Implement Kepler Memory on both Linear and BlockLinear.

Do some corrections in conversion shader instructions.

This option allows picking the compatibility profile since a lot of bugs
are fixed in it. We devs will use this option to easierly debug current
problems in our Core implementation.:wq

shader_ir/decode: Miscellaneous fixes to half-float decompilation

kernel/wait_object: Make GetHighestPriorityReadyThread() a const member function

yuzu/bootmanager: Resolve constructor initializer list warnings

kernel/svc: Name supervisor call 0x36

core: Reorganize boot order

It was possible for "samplers" to be read without being written. This
addresses that.
