 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.

Names now make sense and match 3dbrew.

According to the observation from game and 3dbrew "Used for accessing general NCCH data"

All "subclasses" of DiskArchive are splitted out. This class is useless

Now DiskArchive only serves for SDMC, then it should be just a "SDMCArchive"

ExtSaveData is more similar to SaveData, so let it be a subclass of SaveData

The error checking of SaveDataArchive is completely different from DiskArchive, so it has to be a new class instead of a subclass of DiskArchive.

Same as directory, file shouldn't expose Open either.

Open should not be an interface exposed by Directory because it is the Archive thats implement the methed to open the directory. The service API of 3DS also implies this - Open is not a function of directory service, but is of FS main service
