Thomas Guillemard 9426ef3f06 Rewrite nvservices (#800)
* Start rewriting nvservices internals

TODO:

- nvgpu device interface
- nvhost generic device interface

* Some clean up and fixes

- Make sure to remove the fd of a closed channel.
- NvFileDevice now doesn't implement Disposable as it was never used.
- Rename NvHostCtrlGetConfigurationArgument to GetConfigurationArguments
to follow calling convention.
- Make sure to check every ioctls magic.

* Finalize migration for ioctl standard variant

TODO: ioctl2 migration

* Implement SubmitGpfifoEx and fix nvdec

* Implement Ioctl3

* Implement some ioctl3 required by recent games

* Remove unused code and outdated comments

* Return valid event handles with QueryEvent

Also add an exception for unimplemented event ids.

This commit doesn't implement accurately the events, this only define
different events for different event ids.

* Rename all occurance of FileDevice to DeviceFile

* Restub SetClientPid to not cause regressions

* Address comments

* Remove GlobalStateTable

* Address comments

* Align variables in ioctl3

* Some missing alignments

* GetVaRegionsArguments realign

* Make Owner public in NvDeviceFile

* Address LDj3SNuD's comments
