Memory: Fixed a regression caused by #1695 and #1689.

Reserve enough space in the vector that holds the linear heap memory to prevent relocations of the backing memory when growing too much.

Closes #1790

Kernel: Implemented shared memory.

gitmodules: citra-emu/soundtouch → citra-emu/ext-soundtouch

Kernel/Threads: Dynamically allocate the TLS region for threads.

HLE/Applets: Give each applet its own block of heap memory, and use that when creating the framebuffer shared memory block.

Kernel: Account for automatically-allocated shared memories in the amount of used linear heap memory.

APT: Move the shared font loading and relocation functions to their own subdirectory services/apt/bcfnt.

Applications can request the kernel to allocate a piece of the linear heap for them when creating a shared memory object.
Shared memory areas are now properly mapped into the target processes when calling svcMapMemoryBlock.

Removed the APT Shared Font hack as it is no longer needed.

R0 is used as the last parameter instead of R4.

Cleanup ShaderSetup (Part 1)

Pica: Implement texture type 3 (Projection2D)

Turn ShaderSetup into a class

Implement W-buffer and fix depth-mapping

gdbstub: Silence missing prototype warnings

gl_rasterizer: Fix compilation for debug builds

Pica: PicaShaderConfig is TC and cleared before use

dyncom: Reset the context into user mode correctly

The other mode was system mode.

source: Fix missing logging arguments
