SMB2 Write truncate

[David Mulder]

I see that this is very messy. I'll move on for now. Looks to me like these tests will need to be completely re-written, since the behavior has changed.

Hi David,

it's good that you work on the smb2 tests, thanks!

But watch out for source4/torture/basic/delaywrite.c, the write time
update handling is one of the most complex topic.
Windows behaves differently depending on the OS version and
protocol and also the cross protocol behavior brings a lot of strange
things.

See https://bugzilla.samba.org/show_bug.cgi?id=13541 and
https://bugzilla.samba.org/show_bug.cgi?id=13594 for a lot of work
in progress patches and open questions.

Maybe you want to skip source4/torture/basic/delaywrite.c for now
and do the easy stuff first...

To truncate in SMB2 you can call setinfo on a handle
with SMB_FILE_END_OF_FILE_INFORMATION.

Ah, I missed that SET_INFO call. Thanks Jeremy and Ronnie.
