Kernel/Sessions: Clean up the list of pending request threads of a session when the client endpoint is closed.

It behaves mostly as WaitSynchronizationN with wait_all = false, except for IPC buffer translation.

The target thread of an IPC response will now wake up when responding.
IPC buffer translation is currently not implemented.
Error passing back to svcSendSyncRequest is currently not implemented.

* Services/UDS: Set the proper bit in the ConnectionStatus structure when creating a network.

This lets the application know that the host was successfully added to the session.

* Services/UDS: Reset the connection status when destroying the network

* Services/UDS: Reset the connection status's bitmask of changed nodes after reporting it to the game.

OpenGL: Update comment on AreQuaternionsOpposite with new information

Add basic support for IPC translation for HLE services

Reduces the necessary allocation to max(in_handles, out_handles) rather
than (in_handles + out_handles).

These use the context functions to create and look-up handles for the
user.

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.

Fragment lighting: implement spot light 

While debugging the software renderer implementation, it was noticed
that this is actually exactly what the hardware does, upgrading the
status of this "hack" to being a proper implementation. And there was
much rejoicing.

New service framework

Kernel: Ensure objects are kept alive during ClientSession disconnection

Fixes #2760

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.

Services/UDS: Implement DecryptBeaconData.

Service: Remove unnecessary includes from service.h

Handle service registrations using sm/srv

This function decrypts the encrypted data tags contained in the 802.11 beacon frames.

Add SetHleHandler to ServerPort/ServerSession

HLE: Move SessionRequestHandler from Service:: to Kernel::

This has a huge fallout in terms of needing to fix other files because
all service implementations included that file.

Also enhances the GetServiceHandle implementation to be more accurate.

An Event was used way back then when we didn't have proper working
semaphores. Our Semaphore implementation is good enough now.

This will contain the implementation of the sm (Service Manager) system
module.

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.

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.
