unix package already provides support for working with file extended attributes via Fsetxattr and Fgetxattr syscalls. Windows offers a similar feature implemented by means of NtSetEaFile and NtQueryEaFile syscalls. Those syscalls are provided by this patch. Additionally, NtQueryInformationFile syscall is added. It is required for correct implementation of extended attribute support in library code, as correct invocation of NtQueryEaFile relies on file information returned by said syscall. It also amends the previously accepted NtSetInformationFile syscall.
