Improve kernel IPC related syscalls (#1379)

Browse source 
* Implement session count decrement when the handle is closed

* Remove unused field

* Implement SendSyncRequestWithUserBuffer, SendAsyncRequestWithUserBuffer and ReplyAndReceiveWithUserBuffer syscalls

* Nits

* Fix swapped copy dst/src

* Add missing pointer buffer descriptor write on reply

* Fix IPC unaligned buffer copy and restoring client attributes on reply

* Oops

* Fix SetIpcMappingPermission

* Fix unaligned copy bugs

* Free memory used for temporary IPC buffers
