/**
* This class allows the creation of Handles, which are references to objects that can be tested
* for validity and looked up. Here they are used to pass references to kernel objects to/from the
* emulated process. it has been designed so that it follows the same handle format and has
* approximately the same restrictions as the handle manager in the CTR-OS.
*
* Handles contain two sub-fields: a slot index (bits 31:15) and a generation value (bits 14:0).
* The slot index is used to index into the arrays in this class to access the data corresponding
* to the Handle.
*
* To prevent accidental use of a freed Handle whose slot has already been reused, a global counter
* is kept and incremented every time a Handle is created. This is the Handle's "generation". The
* value of the counter is stored into the Handle as well as in the handle table (in the
* "generations" array). When looking up a handle, the Handle's generation must match with the
* value stored on the class, otherwise the Handle is considered invalid.
*
* To find free slots when allocating a Handle without needing to scan the entire object array, the
* generations field of unallocated slots is re-purposed as a linked list of indices to free slots.
* When a Handle is created, an index is popped off the list and used for the new Handle. When it
* is destroyed, it is again pushed onto the list to be re-used by the next allocation. It is
* likely that this allocation strategy differs from the one used in CTR-OS, but this hasn't been
* verified and isn't likely to cause any problems.

*
* To make a service call, the client must write the command header and parameters to the buffer
* located at offset 0x80 of the TLS (Thread-Local Storage) area, then execute a SendSyncRequest
* SVC call with its Session handle. The kernel will read the command header, using it to marshall
* the parameters to the process at the server endpoint of the session. After the server replies to
* the request, the response is marshalled back to the caller's TLS buffer and control is
* transferred back to it.
*
* In Citra, only the client endpoint is currently implemented and only HLE calls, where the IPC
* request is answered by C++ code in the emulator, are supported. When SendSyncRequest is called
* with the session handle, this class's SyncRequest method is called, which should read the TLS
* buffer and emulate the call accordingly. Since the code can directly read the emulated memory,
* no parameter marshalling is done.
*
* In the long term, this should be turned into the full-fledged IPC mechanism implemented by
* CTR-OS so that IPC calls can be optionally handled by the real implementations of processes, as
* opposed to HLE simulations.
