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.

Fix FAQ Link in Readme

Remove unused imports in game_list_p.h

Display QMessageBox Dialogs For Errors

 - Deleted GetStatus() because it wasn't used anywhere outside of Core::System.
 - Fixed design flaw where the message bar status could be set despite the game being stopped.

Optimized messages that were repetitive and added ability for core errors to specify more details optionally.

- Made LoadKernelSystemMode return a pair consisting of a system mode and a result code (Could use review).
- Deleted ErrorOpenGL error code in favor of just having ErrorVideoCore.
- Made dialog messages more clear.
- Compared archive ID in fs_user.cpp to ArchiveIdCode::NCCH as opposed to hex magic.
- Cleaned up some other stuff.

CAM: use IPCHelper

Split-up kernel.h

swrasterizer: implemented TextureCube

Now that HandleTable doesn't directly depend on WaitObject anymore, this
can be separated from the main kernel.h header.

CMake: Use CMake target properties for all libraries

This isn't necessary anymore since plain Get works correctly for
WaitObjects.
