functions with ntdll equivalent
- replaced status setter/getter for wine async structures with direct
access to a (now included) IO_STATUS_BLOCK structure
- since we now have a IO_STATUS_BLOCK in async_private, we no longer
need in most of the user (derivated) structures a field for
LPOVERLAPPED (it's stored as the IO_STATUS_BLOCK)
- rewrote the async.h users accordingly
- implemented ntdll.Nt{Read|Write}File and let
kernel32.{Read|Write}File(Ex)? use those new ntdll functions
- rewrote smb read/write interfaces to be more ntdll stylish (no
overlapped yet)
dlls/kernel subdir (also splitting 16bit APIs in a separate file)
- implemented ntdll.Nt{Lock|Unlock}File, and made use of those for the
kernel32 equivalent
- implemented a few information classes in NtQueryInformationFile and
NtSetInformationFile (still lots of missing classes)
- enhanced the get_file_info server request in order to implement
correctly NtQueryInformationFile (change time & file alloc size)
- rewrote registry loading to comply with latest changes
