r3253: - added rudimentary support for ntioctl in pvfs
- catch the SIGXFSZ signal, which for some completely insane reason is generated in current Linux systems when you write before the maximum offset in a file (maximum is 2^41 on my box). Why wasn't errno good enough for this? - give the right ntstatus code for large offset write failures (This used to be commit 367f0c2af409e4292f727e8a865762a008fd7e67)
