[PATCH 0/13] add SMB2 server-side copy support - V2

[David Disseldorp]

This change-set adds support for the FSCTL_SRV_COPYCHUNK and
FSCTL_SRV_REQUEST_RESUME_KEY server-side copy SMB2 ioctls, allowing
for network round-trip avoidance during a file copy, i.e.:
http://www.samba.org/~ddiss/slides/snappery_samba/img17.html

Changes since V1:
- Replace failure returns with torture_fail()/_skip()
- Free tevent subreq after receive, rather than waiting for parent recv
- Remove unneeded subreq from vfs_time_audit.c copychunk state
- Alloc tevent reqs for copychunk tracking in skel VFS example code
- Minor white space and debug output cleanups

Feedback appreciated.

Cheers, David
