b3e13d653f Kernel/IPC: Support translation of null handles 
Missed this in my first implementation. Thanks to @wwylele for pointing
out that this was missing.

c27dad4cd1 ResultVal: Remove MoveFrom() 
Replace it with std::move(result_val).Unwrap(), or Foo().Unwrap() in
case you already have an rvalue.

1e8c1ed676 ServiceFramework: Use separate copy of command buffer 
Copy the IPC command buffer to/from the request context before/after the
handler is invoked. This is part of a move away from using global data
for handling IPC requests.

0a7f4f531f Service: Add new ServiceFramework framework for writing HLE services 
The old "Interface" class had a few problems such as using free
functions (Which didn't allow you to write the service handler as if it
were a regular class.) which weren't very extensible. (Only received one
parameter with a pointer to the Interface object.)

The new ServiceFramework aims to solve these problems by working with
member functions and passing a generic context struct as parameter. This
struct can be extended in the future without having to update all
existing service implementations.

8a35f3634e Kernel: Add a dedicated SetHleHandler method to ServerPort/ServerSession 
This allows attaching a HLE handle to a ServerPort at any point after it
is created, allowing port/session creation to be generic between HLE and
regular services.

41a3feea66 HLE: Move SessionRequestHandler from Service:: to Kernel:: 
Most of the code that works with this is or will be in the kernel, so
it's a more appropriate place for it to be.

2668c26a68 Kernel: Map special regions according to ExHeader 
This replaces the hardcoded VRAM/DSP mappings with ones made based on
the ExHeader ARM11 Kernel caps list. While this has no visible effect
for most applications (since they use a standard set of mappings) it
does improve support for system modules and n3DS exclusives.

d27ef4a5d3 Kernel: Removed the priority boost code for starved threads. 
After hwtesting and reverse engineering the kernel, it was found that the CTROS scheduler performs no priority boosting for threads like this, although some other forms of scheduling priority-starved threads might take place.

For example, it was found that hardware interrupts might cause low-priority threads to run if the CPU is preempted in the middle of an SVC handler that deschedules the current (high priority) thread before scheduling it again.

bcad1d6f12 Kernel: Use different thread statuses when a thread calls WaitSynchronization1 and WaitSynchronizationN with wait_all = true. 
This commit removes the overly general THREADSTATUS_WAIT_SYNCH and replaces it with two more granular statuses:

THREADSTATUS_WAIT_SYNCH_ANY when a thread waits on objects via WaitSynchronization1 or WaitSynchronizationN with wait_all = false.

THREADSTATUS_WAIT_SYNCH_ALL when a thread waits on objects via WaitSynchronizationN with wait_all = true.
