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

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.

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.

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.

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.

Previously there was a split where some of the services were in the
Service namespace and others were not.

Moved the HLE command buffer translation task to ServerSession instead of the HLE handler superclass.

Further implementation will happen in a future commit.

Fixes a regression.

Adds the two New3DS-only modules.

3dbrew was used for command information.

3dbrew was used for the command information.

Split SessionRequestHandler::HandleSyncRequest into HandleSyncRequest, TranslateRequest and HandleSyncRequestImpl.

HandleSyncRequest now takes care of calling the command buffer translate function before actually invoking the command handler for HLE services.

KServerPorts now have an HLE handler "template", which is inherited by all ServerSessions created from it.

Sessions and Ports are now detached from each other.
HLE services are handled by means of a SessionRequestHandler class, Interface now inherits from this class.
The File and Directory classes are no longer kernel objects, but SessionRequestHandlers instead, bound to a ServerSession when requested.
File::OpenLinkFile now creates a new session pair and binds the File instance to it.

Pass the triggering ServerSession to the HLE command handler to differentiate which session caused the request.

Kernel/HLE: Service::Interface no longer inherits from any Kernel object, and is now its own standalone class.

Interface is now used by aggregation in ClientPort, to forward service commands to their HLE implementation if needed.

 Kernel/IPC: Use Ports and Sessions as the fundamental building block of Inter Process Communication.

All handles obtained via srv::GetServiceHandle or svcConnectToPort are references to ClientSessions.
Service modules will wait on the counterpart of those ClientSessions (Called ServerSessions) using svcReplyAndReceive or svcWaitSynchronization[1|N], and will be awoken when a SyncRequest is performed.

HLE Interfaces are now ClientPorts which override the HandleSyncRequest virtual member function to perform command handling immediately.

This makes clang-format useful on those.

Also add a bunch of forgotten transitive includes, which otherwise
prevented compilation.
