Kernel/Threads: Don't clear the CPU instruction cache when performing a context switch from an idle thread into a thread in the same process.
We were unnecessarily clearing the cache when going from Process A -> Idle -> Process A, this caused extreme performance regressions.

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.

Kernel/Threads: Don't immediately switch to the new main thread when loading a new process.
This is necessary for loading multiple processes at the same time.
The main thread will be automatically scheduled when necessary once the scheduler runs.

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.

Kernel: Map special regions according to ExHeader
This replaces the hardcoded VRAM/DSP mappings with ones made based on

for most applications (since they use a standard set of mappings) it
does improve support for system modules and n3DS exclusives.

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.
