Kernel/HLE: Use a mutex  to synchronize access to the HLE kernel state between the cpu thread and any other possible threads that might touch the kernel (network thread, etc).

Kernel/Threads: Don't immediately switch to the new main thread when loading a new process.

Kernel/Memory: Acquire the global HLE lock when a memory read/write operation falls outside of the fast path, for it might perform an MMIO operation.

Kernel/HLE: Use a mutex  to synchronize access to the HLE kernel state between the cpu thread and any other possible threads that might touch the kernel (network thread, etc).

This mutex is acquired in SVC::CallSVC, ie, as soon as the guest application enters the HLE kernel, and should be acquired by the aforementioned threads before modifying kernel structures.

Fixed some warnings in the core project.

motion_emu: fix initialization order

This is necessary for loading multiple processes at the same time.
The main thread will be automatically scheduled when necessary once the scheduler runs.

gl_rasterizer: add clipping plane z<=0 defined in PICA

Updated master logo to new logo svg

Fixes a few warnings.

This function is called in clipping, before the pespective divide, and is not used in later rasterization. Thus it doesn't need perspective correction.

hwtested. Current implementation is the correct behavior

gl_shader_gen: simplify and clarify the depth transformation between vertex shader and fragment shader

SwRasterizer/Lighting: implement geometric factor

Refactor MotionEmu into a InputDevice

SwRasterizer/Lighting: implement spot light

* Network: Set and send the game information over enet

Added Callbacks for RoomMember and GetMemberList to Room in preparation for web_services.

dsp_dsp: Remove size assertion in LoadComponent

Fix Spelling/English mistakes

 Services/APT: Use an array to hold data about the 4 possible concurrent applet types (Application, Library, HomeMenu, System)

gl_shader_gen: don't call SampleTexture when bump map is not used

Travis: Use Docker to build for Linux

Implement correct folder structure for CI builds
