gl_rasterizer_cache: Fix incorrect offset in ConvertS8Z24ToZ24S8.

gl_rasterizer_cache: Implement depth format Z16_UNORM.

OpenGL: Use MakeCurrent/DoneCurrent for multithreaded rendering.

Services/BSD: Corrected the return for StartMonitoring according to SwIPC

FileSys: Append the requested path to the filesystem base path in DeleteFile

No need to use ASSERT_MSG with an empty assert message

We were trying to delete things in the current directory instead of the actual filesystem directory. This may fix some savedata issues in some games.

GPU: Always enable the depth write when clearing the depth buffer.

The GPU ignores that register when clearing, but OpenGL obeys the glDepthMask parameter, so we set the depth mask to GL_TRUE when clearing the depth buffer. It will be restored to the correct value automatically on the next draw call.

gl_shader_gen: Implement dual vertex shader mode.

* More improvements to GDBStub
- Debugging of threads should work correctly with source and assembly level stepping and modifying registers and memory, meaning threads and callstacks are fully clickable in VS.
- List of modules is available to the client, with assumption that .nro and .nso are backed up by an .elf with symbols, while deconstructed ROMs keep N names.
- Initial support for floating point registers.

* Tidy up as requested in PR feedback

* Tidy up as requested in PR feedback

- When VertexA shader stage is enabled, we combine with VertexB program to make a single Vertex Shader stage.

Initialized memory for RequestUpdateAudioRenderer and fixed MemoryPoolSection to be more accurate

gl_shader_decompiler: Implement PredCondition::LessThanWithNan.

gl_shader_decompiler: Use FlowCondition field in EXIT instruction.

GPU: Implement the FADD32I shader instruction.

GPU: Corrected the decoding of FFMA for immediate operands.

Port #3335 and #3373 from Citra: "Small SDL fixes" and "Print the actual error preventing SDL from working" (#637)

* Port #3335 and #3373 from Citra

* Fixup: Use the new logging placeholders

Let games/application know that we're offline

Audout "Auto" functions

Minor logging fixes

Audout autos are identical to their counterpart except for the buffer type which yuzu already handles for us.

Since we have no socket implementation we should be returning 0 to indicate we're currently offline.

Services/FS: Return the correct error code when trying to mount a nonexistent savedata.

Improve directory creation in WindowsCopyFiles.cmake

hid: Fix timestamps and controller type.
