Verified to be what GSP does via REing. Fixes invalid virt->phys
translation error spam in some games.

* IncomingDisplayTransfer: Triggered just before a display transfer is performed.

* BufferSwapped: Triggered when the frames flip

Namely OpenFileDirectly, OpenDirectory and OpenArchive

Previously it would just re-read the already decoded instruction and extract the immediate value.

Named the service functions in am:app as per 3dbrew.

This fixes an illegal read loop in Steel Diver

They'll be reset if needed during the next svcWaitSynchronization call (if there's any pending)

It tells the GPU to not swizzle/de-swizzle the input during the transfer.

Changes the log to use hex in the parameter list instead of decimal.

"signed/unsigned mismatch"

This commit fixes several kernel object leaks. The most severe of them
was threads not being removed from the private handle table used for
CoreTiming events. This resulted in Threads never being released, which
in turn held references to Process, causing CodeSets to never be freed
when loading other applications.

Also a side-benefit of not having implementation-defined behavior.

Buffer lengths should be size_t, and file offsets should be u64.

This is exposed in the GUI as a new "CiTrace Recording" widget.

Playback is implemented by a standalone 3DS homebrew application (which only runs reliably within Citra currently; on an actual 3DS it will often crash still).

Applets are now cleaned up in AppletUpdateEvent after calling their respective Update method.

binary segments (code, rodata, data) instead of just blindly allocating
a large chunk of dummy memory.
