Log:
[KERNEL32]: Rewrite the File Change Notification APIs since they were pretty much wrong
(not surprising as we don't implement the functionality in the kernel/filesystems).
[KERNEL32]: Enable support for asynchronous I/O callbacks with SxS/Fusion activation
context support. Right now only added to the file Change notification APIs, but ReadFileEx
and WriteFileEx should use them too.
