In both cases, we weren't actually returning anything, which is
undefined behavior.

Just makes the definitions a little bit more tidy.

fsp_srv: Unstub SetCurrentProcess

input_common/sdl_impl: Minor cleanup in SDLState constructor

This just acts as a basic setter for a given PID value and performs no
further checking, so we can just store the passed in value.

kernel/thread: Amend conditional test and assignment within UpdatePriority()

CMakeLists: Raise minimum Boost requirement to 1.66.0

Required due to bugfix in boost for changed template resolving rules in GCC 7.3.0 in C++17 mode

core: Move PageTable struct into Common.

We don't need to universally capture by reference. We specifically just
need to capture the this pointer.

Specifying the time unit itself is sufficient here.

gl_rasterizer: Skip zero addr/sized regions on flush/invalidate.

ipc_helpers: Allow pushing and popping floating-point values

externals: Update opus to latest master

kernel/thread: Actually remove the definition of ExitCurrentThread()

video_core: Refactor to use MemoryManager interface for all memory access.

memory: Simplify rasterizer cache operations.

Correct CNTPCT from using CPU Cycles to using Clock Cycles

Certain values that are passed through the IPC buffer are actually
floating point values, not solely integral values.

Prevents yuzu from getting 2000+ warnings in MSVC in a future change.

This was intended to be removed in
51d7f6bf, but I guess I forgot to
actually save the file like a dingus.

CMakeLists: Remove now-unnecessary GCC special-casing

kernel/thread: Remove WaitCurrentThread_Sleep() and ExitCurrentThread()

gpu: Use host address for caching instead of guest address.

Puts the operation on global state in the same places as the rest of the
svc calls.

Rather than make a global accessor for this sort of thing. We can make
it a part of the thread interface itself. This allows getting rid of a
hidden global accessor in the kernel code.

Aims to disambiguate why each priority instance exists a little bit.
While we're at it, also add an explanatory comment to UpdatePriority().

This condition was checking against the nominal thread priority, whereas
the kernel itself checks against the current priority instead. We were
also assigning the nominal priority, when we should be assigning
current_priority, which takes priority inheritance into account.

This can lead to the incorrect priority being assigned to a thread.

Given we recursively update the relevant threads, we don't need to go
through the whole mutex waiter list. This matches what the kernel does
as well (only accessing the first entry within the waiting list).

The kernel keeps the internal waiting list ordered by priority. This is
trivial to do with std::find_if followed by an insertion.

Port citra-emu/citra#3924: "citra_qt: Settings (configuration) rework"

This issue has since been fixed in newer versions of Boost, so we don't
need to worry about this anymore.

video_core/morton: Miscellaneous changes

vk_sampler_cache: Implement a sampler cache
